Chapter V Description of parameters
8. PID
The output of process PID control is selected as the operating frequency. It is generally used in field closed-loop
control of process, such as constant pressure closed-loop control and constant tension closed-loop control.
When applying PID as the frequency source, the relevant parameters of FA group “PID function" need to be set.
9. Communication given
Refers to the frequency given by the communication method
The upper computer gives the data through the communication address
0×1000. The data format is
-100.00 %~100.00 %, and 100.00 % refers to the percentage of the maximum frequency F0 - 16.
F0 - 04 reverse control prohibited
0～1 [0]
0: motor allows reverse rotation
1: the motor is not allowed to reverse.
In fact, negative frequency is prohibited. When reverse operation is prohibited and reverse operation is
prohibited, the frequency inverter keeps running at 0 Hz.
F0 - 04 = 1 should be set when the motor is not allowed to rotate reversely.
F0 - 05 phase sequence direction
0～1 [0]
0: standard phase sequence.
1: carry out phase sequence exchange. (The direction of rotation of the motor changes)
F0 - 06 start protection selection
0～1 [0]
0: start unprotects. As long as there is a start command and there is no fault, the frequency inverter will output
and run.
1: start protection.
If the operation command of the frequency inverter is valid at power-up time (for example, the terminal operation
command is closed before power - up), then the frequency inverter will not respond to the operation command,
You must remove the operation command once before the frequency inverter responds.
If the operation command is valid at the time of frequency inverter fault reset and the frequency inverter does not
respond to the operation command, the operation command must be removed before the operation protection state
can be eliminated.
It can prevent the danger caused by the motor responding to the operation command when the motor is powered on
or when the fault is reset without knowing.
F0 - 07 jog. K key function selection
0～4 [0]
The JOG.K key is a multi-function key. The function of the JOG.K key can be set through this function code. This key
can be used to switch between shutdown and operation.
0: this key has no function.
1: keyboard command and remote operation switch. It refers to the switch of command source, that is, the
switch between current command source and keyboard control (local operation). If the current command source is
keyboard - controlled, this key function is invalid.
2: forward and reverse switching
Switches the direction of the frequency command through the jog. K key This function is only valid when the
command source is the command channel of the operation panel.

Frequency
Time
Figure 5 - 1 schematic diagram of acceleration and deceleration time
HV480 defines a total of 4 groups of acceleration and deceleration times. The user can use the digital input
terminal X to switch between selections. The four groups of acceleration and deceleration times are set by the
following function codes:
Group 1: F0 - 10, F0 - 11; Group 2: F6 - 17, F6 - 18;
Group iii: F6 - 19, F6 - 20; Group 4: F6 - 21, F6 - 22.
F0 - 12 acceleration / deceleration time unit
0～2 [1]
0: the time unit is 1s.
1: the unit of time is 0.1 s.
2: the unit of time is 0.01 s.
Notes:
When modifying this function parameter, the number of decimal points displayed in the four groups of
acceleration and deceleration times will change, and the corresponding acceleration and deceleration times
will also change. Special attention should be paid to this during application.
- 60 -
Chapter V Description of parameters
F0 - 13 acceleration and deceleration time reference
0～2 [0]
frequency
0: the reference frequency is the maximum frequency (F0 - 16)
1: set the frequency at the reference frequency.
When F0 - 13 is selected as 1, the acceleration and deceleration time is related to the set frequency. If the set
frequency changes frequently, the acceleration of the motor will change. Attention should be paid when applying.
2: 100 Hz at reference frequency.
F0 - 14 shutdown mode
0～1 [0]
0: after the deceleration
Stop command is valid, the frequency inverter will reduce the output frequency according to the deceleration
time, and stop after the frequency is reduced to 0.
1: after the free
Stop command is valid, the frequency inverter will terminate the output immediately. At this time, the motor will
stop freely according to the mechanical inertia.
F0 - 15 droop control rate
0～10.00hz [0.00hz]
The droop rate allows for a slight speed difference between the master station and the slave station, thus
avoiding the rush between them. The default value for this parameter is 0.
Only when the main engine and the slave engine adopt the speed control mode will the droop rate need to be
adjusted. For each transmission process, the appropriate droop rate needs to be gradually found in practice. It is
recommended not to set F0 - 15 too large, otherwise the steady-state speed will drop significantly when the load is
large. Both the master and slave must set the droop rate.
Droop speed = synchronous frequency * output torque * (droop rate / 10)
For example: F0 - 15 = 1.00
50 Hz synchronous frequency rate, 50 % output torque, real frequency rate of frequency changer = 50 Hz - 50 *
(50 %)
(1.00/10) = 47.5hz
F0 - 16 maximum frequencies
50.00～500.00hz [50.00hz]
The analog input, pulse input (X5), multi-segment instruction, etc. are all 100.0 % of the respective calibration of
F0 - 16 when they are used as frequency sources.
F0 - 17 upper frequency sources
0～5 [0]
0: set by F0 - 18.

5: through communication settings.
F0 - 18 upper limit frequency
Upper limit frequency ~ maximum frequency [ 50.00 Hz ]
F0 - 19 upper frequency offset
Upper limit frequency ~ maximum frequency [ 50.00 Hz ]
When the upper limit frequency source is set to analog quantity or pulse setting, F0 - 19 is used as the offset
amount of the set value, and the offset frequency is superposed with the upper limit frequency value set by F0 - 17 as
the set value of the final upper limit frequency.

Chapter V Description of parameters
F0 - 20 lower limit frequency
0.00 Hz ~ upper limit frequency [ 0.00 Hz ]
F0 - 21 operating formula for setting frequency lower 0～2 [0]
than lower limit frequency
When the frequency command is lower than the lower limit frequency set by F0 - 20, the frequency inverter can
be stopped, run at the lower limit frequency, or run at zero speed. Which operating mode can be set by F0 - 21
(operating mode with the set frequency lower than the lower limit frequency).
F0 - 22 carrier frequency
0.5 kHz ~ 16 kHz [model determination]
This function adjusts the carrier frequency of the frequency inverter. By adjusting the carrier frequency, the noise
of the motor can be reduced, the resonance point of the mechanical system can be avoided, the line current to the
floor drain can be reduced, and the interference generated by the frequency inverter can be reduced.
When the carrier frequency is low, the higher harmonic component of the output current increases and the motor
loss increases, and the temperature rise of the motor increases.
When the carrier frequency is high, the motor loss decreases and the temperature rise of the motor decreases,
but the frequency inverter loss increases and the frequency inverter temperature increases.
The rise increases and the interference increases. Adjusting the carrier frequency will affect the following
performance:
Carrier frequency
Low → high
Motor noise
Big → small
Output current waveform
Poor → good
Motor temperature rise
High → low
Temperature rise of frequency
Low → high
inverter
Leakage current
Small → big
External radiation interference
Small → big
The factory setting of carrier frequency is different for frequency inverters with different power. Although users
can modify it according to their needs, and they need to pay attention: if the carrier frequency setting is higher than
the factory value, and the temperature rise of the frequency inverter radiator will increase. At this time, users need to
use the frequency inverter by derating; otherwise the frequency inverter is in danger of overheating alarm.
F0 - 23 carrier frequencies adjusts with load size
0～1 [1]
The carrier frequency is adjusted with the load, which means that when the frequency inverter detects that the
load exceeds the rated level, and it will automatically reduce the carrier frequency so as to reduce the temperature
rise of the frequency inverter.
When the load decreases to a certain extent, the carrier frequency gradually returns to the set value. This
function can reduce the chance of over-heating alarm of frequency inverter.
F0 - 24 LED shutdown operation display selection
0～1 [0]
0: shutdown operation display is separated.
During operation, the LED display content is set by F0 - 37 / F0 - 38.
When shutting down, the LED display content is set by F0 - 39.
1: stop operation display does not separate
- 62 -
Chapter V Description of parameters
During operation, the LED display content is set by F0 - 37 / F0 - 38.
When shutting down, the LED display content is set by F0 - 37 / F0 - 38.
F0 - 26 digital setting frequency shutdown memory
0～1 [1]
selections
This function is only valid when the frequency source is set digitally.
0: “no memory" means that after the frequency inverter is shut down, the digital set frequency value is restored
to F0 - 09 (preset frequency) values, keyboard ▲ and ▼ keys or frequency correction by terminals up and down are
cleared.
1: “memory" means that after the frequency inverter is shut down, the digital set frequency will remain the set
frequency at the time of the last shutdown. Frequency correction by keys ▲, ▼ or terminals up and down remains
valid.
F0 - 27 runtime frequency command up / down reference
0～1 [1]
This parameter is valid only if the frequency source is set digitally.
0: the operating frequency is the benchmark.
When the ▲, ▼ keys or terminals up / down of the keyboard are operated, what method is used to correct the
set frequency, that is, the target frequency rate is increased or decreased based on the operating frequency.
1: set frequency as reference.
When the ▲, ▼ keys or terminals up / down of the keyboard are operated, what method is used to correct the
set frequency, that is, the target frequency the rate is increased or decreased based on the set frequency.
The difference between the two settings is obvious when the frequency inverter is in the process of acceleration
and deceleration, that is, if the frequency of operation of the frequency inverter, When the rate is different from the set
frequency, the different choices of this parameter are very different.
F0 - 28 motor selection
0～1 [0]
HV480 supports the application of time-sharing drive of two motors by frequency inverters. The two motors can
respectively set motor nameplate parameters, independent parameter tuning, select different control modes, and
independently set parameters related to operation performance, etc. The user selects the current motor parameter
group through the F0 - 28 function code, and who can also switch the motor parameters through the digital quantity
input terminal X. When the function code selection conflicts with the terminal selection, the terminal selection shall
prevail
0: motor 1.
The corresponding functional parameter groups of motor parameter group 1 are f1 group and F2 group.
1: motor 2
Motor parameter group 2 corresponds to functional parameter group FB.
F0 - 29 auxiliary frequency source y
0～9 [0]
When the auxiliary frequency source is given a channel as an independent frequency (i.e. the frequency source
is selected as X to Y switch), its usage is the same as that of the main frequency source X. the usage method can
refer to the relevant description of F0 - 03.
When the auxiliary frequency source is used for superposition and given (i.e. the composite implementation
frequency of the main frequency source X and the auxiliary frequency source Y is given), attention should be paid to:
1. When the auxiliary frequency source is given by numbers, the preset frequency (F0 - 09) does not work, and
the user can select the preset frequency (F0 - 09) through the keyboard ▲, ▼ key (or up and down of multi-function
input terminal) adjusts the frequency directly on the basis of the main given frequency.
2. When the auxiliary frequency source is given by analog input (AI1, AI2, and AI3) or pulse input, the input
setting of 100 % corresponds to the auxiliary frequency source range, which can be set through F0 - 30 and F0 - 31.
3. Frequency source for pulse input timing, similar to analog given. Tips: the selection of the auxiliary frequency
source Y and the selection of the main frequency source X cannot be set to the same channel, i.e. F0 - 03 and F0 -
29 should not be set to the same value, otherwise it will easily cause confusion.

F1-06～F1-10 is parameters of asynchronous motors. These parameters are generally not found on the motor
nameplate and need to be automatically tuned by the frequency inverter. Among them, “asynchronous motor static
tuning" can only obtain F1-06～F1-08 three parameters, while " asynchronous motor complete tuning" can obtain not
only all five parameters here, but also encoder phase sequence, current loop PI parameters, etc.
When changing the rated power of the motor (F1 - 01) or the rated voltage of the motor (F1 - 02), the frequency
inverter will automatically modify the F1 - 06 ~ F1 - 10 parameter values to restore these 5 parameters to the
common standard Y series motor parameters. If it is impossible to tune the asynchronous motor on site, you can
enter the above-mentioned corresponding function code according to the parameters provided by the motor
manufacturer.
F0 - 29 motor parameters self - tuning
0～3 [0]
0: no operation.
1: simple static self - tuning.
It is suitable for asynchronous motors where large inertia loads are not easy to disengage and cannot be
rotated.
2: rotational self - tuning
During the complete setting process, the frequency inverter will first perform static setting, and then accelerate
to 80 % of the rated frequency of the motor according to the acceleration time F0 - 10. After maintaining for a period
of time, the frequency inverter will slow down and shut down according to the deceleration time F0 - 11 and end the
setting.
3. Advanced static self-tuning
Is applicable to the case where there is no encoder, and the motor parameters are self-learned when the motor
is at rest (at this time, the motor may still have slight shaking)
Description:
1. Tuning supports motor tuning in keyboard operation mode, terminal mode and communication mode.
2. In order to ensure the optimal control performance of the frequency inverter during vector control, please
disconnect the load from the motor and use rotational tuning to self-learn the motor parameters; otherwise it will
affect the vector control effect. Please use static tuning 2 when the motor has a large inertia load which is not easy to
disengage and vector control is required.

The frequency inverter operates at different frequencies, and different PI parameters of the speed loop can be
selected.
When the operating frequency is less than the switching frequency 1 (F2 - 02), the speed loop pi adjustment
parameters are F2 - 00 and F2 - 01.
When the operating frequency is greater than the switching frequency 2, the speed loop pi adjustment parameters
are F2 - 03 and F2 - 04.
The speed loop pi parameters between switching frequency 1 and switching frequency 2 are linearly switched by two
sets of pi parameters, as shown in figure 5 - 03:
Parameter
Frequency
Figure 5 - 03 pi parameter diagram
By setting the proportional coefficient and the integration time of the speed regulator, the speed dynamic
response characteristics of the vector control can be adjusted.
Increasing the proportional gain and decreasing the integration time can accelerate the dynamic response of the
speed loop. However, too much proportional gain or too little integration time may cause the system to oscillate.
The suggested adjustment method is:
If the factory parameters cannot meet the requirements, fine-tune them based on the factory value parameters
to increase the proportion and benefit first, so as to ensure that the system does not oscillate. Then reduce the
integration time so that the system has faster response characteristics and less overshoot.
For vector control without speed sensor, this parameter is used to adjust the speed stability accuracy of the
motor: when the motor is loaded with low speed, this parameter is increased, and vice versa.
Note: improper setting of pi parameters may lead to excessive speed overshoot. Even when overshoot falls
back, over-voltage faults occur.

Description:
F2 - 09 is used to select the setting source of the upper torque limit. When setting through analog quantity,
PULSE pulse and communication, 100 % of the corresponding setting corresponds to F2 - 10, while 100 % of F2 - 10
is the rated torque of the frequency inverter. For AI1, AI2, AI3, X5 settings, please refer to the introduction of F4 AI
curve.
When the selection is communication setting
The host computer writes -100.00% ～ 100.00% of the data through the communication address 0×1000, of
which 100.00 % corresponds to F2 - 10.
F3 Group V/F control parameters
This group of function codes is only valid for V/F control and invalid for vector control.
F3 - 00 V/F curve setting
0～11 [0]
0: straight line V/F.
Suitable for common constant torque load.
1: multipoint V/F.
Suitable for special loads such as dehydrators and centrifuges at this time, by setting F3 - 03 to F3 - 08
parameters, any desired VF relation curve can be obtained.
2: square V/F. Suitable for centrifugal loads such as fans and water pumps.
3 ~ 8: VF relation curve between straight line VF and square VF.
10: VF complete separation mode.
At this time, the output frequency of the frequency inverter and the output voltage are independent of each other.
The output frequency is determined by the frequency source, while the output voltage is determined by F3 - 13 (VF
separated voltage source).
VF complete separation mode is generally used in induction heating, frequency inverter power supply, torque
motor control and other occasions.
11: VF semi-detached mode.
V and F are proportional in this case, but the proportional relationship can be set by the voltage source F3 - 13,
and V and F are the relationship is also related to the rated voltage and frequency of F1 group motors.
Assuming that the voltage source input is X (X is a value of 0 - 100 %), the relationship between the frequency
inverter output voltage v and frequency f is: V/F = 2 * X * (rated voltage of motor) / (rated frequency of motor)

F3 - 01 torque boost
0.0 % ~ 30 % [ model determination ]
F3 - 02 torque boost cutoff frequency
0.00 Hz ~ maximum output frequency [ 50.00 Hz ]
In order to compensate for the V/F control low frequency torque characteristics, the frequency inverter output
voltage is compensated for some lift at low frequency. However, the setting of torque increase is too large, the motor
is easy to overheat, and the frequency inverter is easy to over current.
This parameter is recommended to be increased when the load is heavy and the starting torque of the motor is
insufficient. The torque lift can be reduced when the load is light.
When the torque increase is set to 0.0, the frequency inverter will automatically increase the torque. At this time,
the frequency inverter will automatically calculate the required torque increase value based on the motor stator
electrical resistance and other parameters.
Torque boost torque cutoff frequency: under this frequency, the torque boost torque is valid. If it exceeds this set
frequency, the torque boost will fail. See figure 5 - 04 for details.

Too high voltage setting at low frequencies may cause the motor to overheat or even burn down, and the

F3 - 09 VF slip compensation gain
0%～200.0% [0.0%]
VF slip compensation can compensate the motor speed deviation of asynchronous motor when the load
increases, so that the motor speed can basically remain stable when the load changes.
VF slip compensation gain is set to 100.0 %, which indicates that the compensated slip is the rated slip of the motor
when the motor is under rated load.
When adjusting VF slip compensation gain, it is generally based on the principle that the motor speed is
basically the same as the target speed under the rated load. When the motor speed is different from the target value,
it is necessary to adjust the gain appropriately.
F3 - 10 VF over-excitation gain
0～200 [64]
In the process of frequency inverter deceleration, over-excitation control can suppress the rise of bus voltage
and avoid over-voltage fault. The greater the over-excitation gain, the stronger the suppression effect.
When the frequency inverter is prone to over-voltage alarm during deceleration, it is necessary to increase the
over-excitation gain. However, the over-excitation gain is too large, which easily leads to an increase in the output
current and needs to be weighed in the application.
When the inertia is very small, no voltage rise will occur during motor deceleration, it is recommended to set the
over-excitation gain to 0. It is also recommended to set the over-excitation gain to 0 when there is a braking
resistance.
F3 - 11 VF oscillation suppression gain
0 ~ 100 [model determination]
The gain is chosen to be as small as possible on the premise of validly suppressing oscillation so as not to
adversely affect VF operation. Please select the gain of 0 when the motor does not oscillate. Only when the motor is
obviously oscillating can the gain be appropriately increased. The greater the gain, the more obvious the suppression
of oscillation is.
When using the function of suppressing oscillation, it is required that the rated current and no-load current
parameters of the motor are accurate, otherwise VF oscillation suppression effect is not good.

F3 - 14 VF separated voltage digital setting

VF separation is generally used in induction heating, frequency inverter power supply, torque motor control and
other occasions.
When VF separation control is selected, the output voltage can be set through function code F3 - 14, or it can
come from analog quantity, multi - Segments instruction, PLC, PID or communication given. When non-digital setting
is used, each set 100 % corresponds to the rated voltage of the motor, and when the percentage set by the analog
output is negative, the set absolute value is taken as the valid setting value.

5. Multiple instructions
When the voltage source is a multi-segment instruction, F5 group and FC group parameters should be set to
determine the correspondence between a given signal and a given voltage. The FC group parameter multi-segment
command gives 100.0 %, which is the percentage relative to the rated voltage of the motor.

Chapter V Description of parameters
The above function codes are generally used to correct the zero offset of the analog output and the deviation of
the output amplitude. It can also be used to customize the required AO output curve.
If the zero offset is represented by “b", the gain is represented by k, the actual output is represented by y, and
the standard output is represented by x, the actual output is: Y = kX + b * 10V.
Among them, the zero offset coefficient of AO1 and AO2 is 100 % corresponding to 10v (or 20mA), and the
standard output refers to the output of 0V - 10V (or 0mA - 20mA) corresponding to the amount indicated by the
analog output without zero offset and gain correction.
For example, if the analog output content is operating frequency, it is expected to output 8v at frequency 0 and
3v at maximum frequency, then the gain should be set to " - 0.50" and the zero offset should be set to " 80 %".

The above function code is used to set the relationship between the analog input voltage and the set value it
represents.
When the voltage of analog input is greater than the set “maximum input" (F5 - 26), the analog voltage is calculated
according to “maximum input". Similarly, when the analog input voltage is less than the set " minimum input" ( F5 -
24 ), it is calculated as the minimum input or 0.0 % based on the setting of " AI is lower than the minimum input
setting selection" ( F5 - 40 ).
When the analog input is a current input, 1ma current is equivalent to 0.5v voltage.
AI1 input filtering time is used to set the software filtering time of AI1. When the analog quantity in the field is
easily interfered, please increase the filtering time to stabilize the detected analog quantity. However, the larger the
filtering time is, the slower the response speed to the analog quantity detection will be. How to set it needs to be
weighed according to the actual application situation
In different applications, the meaning of the nominal value corresponding to 100.0 % set by simulation is
different. Please refer to the description of each application section for details.
