Analog quantity inputs AI1 to AI3 have the function of setting value jump. The skip function refers to setting the
analog quantity corresponding to changes in the upper and lower sections of the skip point.
The value is fixed to the value of the jumping point.
Example:
The voltage of analog quantity input AI1 fluctuates up and down 5.00V, ranging from 4.90V to 5.10V. the
minimum input 0.00 V of AI1 corresponds to 0.0 % and the maximum input 10.00V corresponds to 100. %. And then
the detected AI1 corresponds to a fluctuation of 49.0 % ~ 51.0 %.
Setting AI1 set jumping point F5 - 65 to 50.0 % and setting AI1 set jumping amplitude F5 - 66 to 1.0 %, the
corresponding setting of the obtained AI1 input after the jump function processing is fixed to 50.0 %, AI1 is converted
into a stable input and the fluctuation is eliminated.
F6 Group start-stop control
F6 - 00 starting operation mode
0～2 [0]
0: direct starting
If the starting DC braking time is set to 0, the frequency inverter will start operating from the starting frequency.
If the starting DC braking time is not 0, DC braking will be performed first, and then operation will start from the
starting frequency. Suitable for small inertia load, where the motor may rotate during start - up
1: speed tracking and restarting
The frequency inverter first judges the speed and direction of the motor, then starts at the tracked frequency of
the motor, and during rotation the motor starts smoothly and without impact. It is suitable for the restart of large
inertia load with instantaneous power failure. In order to ensure the performance of speed tracking and restart, it is
necessary to accurately set the f1 parameters of the motor.
2: The pre-excitation starting of the asynchronous machine
Is only valid for the asynchronous motor, which is used to establish the magnetic field before the motor runs.
Refer to the description of function codes F6 - 05 and F6 - 06 for pre-excitation current and pre-excitation time.
If the pre-excitation time is set to 0, the frequency inverter cancels the pre-excitation process and starts from the
starting frequency. If the pre-excitation time is not 0, the motor can be pre-excited before starting, which can improve
the dynamic response performance of the motor.
F6 - 01 speed tracking method
0～2 [0]
In order to complete the speed tracking process in the shortest time, select the way that the frequency inverter
tracks the motor speed:
0: starting from shutdown frequency
This method is usually used to track down from the frequency of power failure.
1: starting from zero speed
Track up from zero frequency, and use it in case of power failure for a long time before starting.
2: starting from the maximum frequency
Track down from the maximum frequency and use the general power generating load.

When speed tracking is restarted, select the speed of speed tracking.
The larger the parameter, the faster the tracking speed However, setting too large may lead to unreliable
tracking results.
F6 - 03 startup frequency
0.00Hz～10.00Hz [0.00Hz]
F6 - 04 startup frequency hold time
0.0s～100s [0.0s]
In order to ensure the motor torque during starting, please set the appropriate starting frequency. In order to fully
establish magnetic flux when starting the motor, it is necessary to keep the starting frequency for a certain period of
time.
The relationship between starting frequency and starting time is shown in figure 5 - 18.

Notes:
The starting frequency F6 - 03 is not limited by the lower limit frequency.
When the set target frequency is less than the starting frequency, and the frequency inverter will not start and
will be in standby mode.
During forward and reverse switching, the start frequency holding time does not work.
The startup frequency holding time is not included in the acceleration time, but is included in the operation time
of the simple PLC.
F6-05 start DC brake current / pre-excitation current
0%～100% [0%]
F6-06 start DC brake time / pre - excitation time
0.0s～100.0s [0.0s]
Start the direct current brake, which is usually used to stop the running motor before starting. The pre-excitation
is used to set up a magnetic field before starting the asynchronous motor to improve the response speed.
If it is valid when the startup mode is direct startup at this time, the frequency inverter performs direct current
braking according to the set starting direct current braking current, and starts to run after the starting direct current
braking time. If the DC braking time is set to 0, it will be started directly without direct current braking.
If the starting mode is asynchronous machine pre-excitation starting, the frequency inverter first establishes a
magnetic field in advance according to the set pre-excitation current, and then starts to run after the set
pre-excitation time. If the pre-excitation time is set to
0, it will be started directly without going through the
pre-excitation process.

F7 - 01 is used to select the torque setting source. There are 8 torque setting methods.
Torque setting uses relative value, 100.0 % corresponding to the rated torque of the motor. Setting range -
200.0 % ~ 200.0 %, table the maximum torque of the Ming frequency inverter is twice the rated torque of the
frequency inverter.
When the torque is given to be positive, the frequency inverter is running in forward rotation
When the torque is given to be negative, the frequency inverter is running in reverse rotation
0: digital setting ( F7 - 03 )
Means that the target torque directly uses the F7 - 03 setting value.
1: AI1
2: AI2
3: AI3
Refers to the target torque is determined by the analog input terminal.
AI is given as torque, the voltage / current input corresponds to 100.0 % set, which refers to the percentage of
F7 - 03 set with respect to the torque number.
4. PULSE pulse (X5)

F7 - 02 small torque stop compensation
-50.0%～50.0% [0.0%]
During torque control, the setting torque is too small to stop the traction load. At this time, F7 - 02 is added, and
the setting goes bigger, and the greater the torque during shutdown (note: not deceleration).
F7 - 04 torque control speed limit source
0～1[0]
0: set speed limit by F7 - 05 and F7 - 06.
When the torque setting is greater than 0, the upper frequency limit is given by F7 - 05; When the torque
setting is less than 0, the upper frequency limit is set by F7 - 06.
1: set by frequency source F0 - 03 frequency source.
When the torque is set to be 0, the upper frequency limit is determined by the frequency selected by F0 - 03.
When the torque is set to be 0, the upper frequency limit is F0 - 03 negative number of selected frequency.
F7-05Torque control forward maximum frequency
0.00Hz ~ maximum frequency [50.00hz]
F7-06Torque control reverse maximum frequency
0.00Hz ~ maximum frequency [50.00hz]
During torque control, the acceleration / deceleration time of the upper frequency limit is set at F7 - 09
(acceleration) / F7 - 10 (deceleration).
Used to set the maximum forward or reverse operating frequency of the frequency inverter in torque control
mode.
When the frequency inverter torque is controlled, if the load torque is less than the motor output torque, the
motor speed will continuously increase. In order to prevent accidents such as speeding in mechanical systems, it is
necessary to limit the maximum rotational speed of the motor during torque control.
If it is necessary to dynamically and continuously change the maximum frequency of torque control, the upper
limit frequency can be controlled.
F7-07 Torque given rise time
0.00s～650.00s [0.00s]
F7-08 Given torque drop time
0.00s～650.00s [0.00s]
Under the torque control mode, the difference between the motor output torque and the load torque determines
the speed change rate of the motor and the load. Therefore, the speed of the motor may change rapidly, which will
cause problems such as noise or excessive mechanical stress. By setting the torque control acceleration and
deceleration time, the rotation speed of the motor can be changed smoothly.
However, when torque is required to respond quickly, torque control acceleration and deceleration time should
be set to 0.00s.
F7-09 Torque control frequency rise time

F8 - 02 = 4, the frequency inverter starts timing when it starts. After reaching the set timing running time, the
frequency inverter stops automatically and the multi-function DO outputs an on signal at the same time.
Each time the frequency inverter starts, it starts counting from 0. The remaining running time of timing can be
checked through u0 - 20.
The timing run time is set by F8 - 05 / F8 - 06 and the time unit is min.

the mechanical load.
When the set frequency is within the jump frequency range, the actual operating frequency will run in the jump
closer to the set frequency. By setting the jumping frequency, the frequency inverter can avoid the mechanical
resonance point of the load.
HV480 can set 4 hopping frequency points. If all 4 hopping frequencies are set to 0, the hopping frequency
function will be cancelled.

0～2 [0]
In the event of an instantaneous power failure or a sudden drop in voltage, the frequency inverter compensates
for the drop in DC bus voltage of the frequency inverter by reducing the output speed, so as to maintain the
frequency inverter's continuous operation.
0: this function is invalid.
1: slow down.
When the power is cut off or the voltage drops suddenly, the frequency inverter slows down. When the bus
voltage returns to normal, the frequency inverter is normal. Speed up recovery to set frequency operation. The basis
for judging the bus voltage to return to normal is that the bus voltage is normal and the duration exceeds the set time
of F8 - 21.
2: slow down and shut down.
In the event of an instantaneous power failure or a sudden drop in voltage, the frequency inverter slows down

F8 - 23 ~ F8 - 32 are specially designed for the textile industry. They are used in textile, chemical fiber and other
industries, as well as in occasions where horizontal movement and winding functions are required. They are simply
referred to as swing frequency functions.
The pendulum frequency function is applicable to the pendulum frequency function. It refers to the frequency
output by the frequency inverter, which swings up and down around the set frequency. The track of the operating
frequency on the time axis is shown in figure 5 - 24. The swing amplitude is set by F8 - 23 and F8 - 24. When F8 - 24
is set to 0, the pendulum frequency will not work at this time.

This parameter is used to determine the reference amount of the swing.
0: relative center frequency (current frequency source), variable swing system. The swing amplitude changes
with the change of the center frequency (set frequency).

F8 - 24 swing amplitude

F8 - 25 sudden jump frequency amplitude
0.0%～50.0% [0.0%]
This parameter is used to determine the values of swing amplitude and sudden jump frequency.
When setting the swing relative to the center frequency (F8 - 23 = 0), swing aw = setting frequency × swing
amplitude F8 - 24.
When setting the swing relative to the maximum frequency (F8 - 23 = 1), the swing aw = maximum frequency F0
- 16 × swing amplitude F8-24.
The sudden jump frequency amplitude is the percentage of the sudden jump frequency relative to the swing
amplitude when the swing frequency is running, i.e. sudden adjustment frequency = swing amplitude aw × sudden
jump frequency amplitude F8 - 25.
If the swing amplitude is selected relative to the center frequency (F8 - 23 = 0), the sudden adjustment
frequency is a change value.
If the swing amplitude is selected relative to the maximum frequency (F8 - 23 = 1), the sudden adjustment
frequency is a fixed value.

dividing F8 - 30.
During the fixed length control process, the length reset operation can be performed through the multi-function X

terminal function needs to be set to “counter input" (function 25) in the application. When the pulse frequency is high,
X5 port must be used.
When the count value reaches the set count value F8 - 31, the multifunction digital DO outputs the “set count

When the count value reaches the specified count value F8 - 32, the multifunction digital DO outputs the
“specified count value reaches" ON signal. At this time, the counter continues counting until “set count value" when
the counter stops.
The specified count value F8 - 32 should not be greater than the set count value F8 - 31. The count value can be

0～1 [1]
F9 - 01 motor overload protection gain
0.20～10.00 [1.00]
F9 - 00 = 0: motor overload protection is invalid.
F9 - 00 = 1: at this time, the frequency inverter judges whether the motor is overloaded according to the inverse
time limit curve of the motor overload protection.
The shortest time to report motor overload is 2 minutes. If you need to adjust motor overload current and time,
please Set F9 - 01 (motor overload protection gain). The curve of motor overload current and overload time is shown
in the following figure:
Overload time
/min
Load /%
Figure 5 - 25 overload current vs. overload time curve
For example: if the motor is required to run at 120 % of the motor current for 30 minutes to report overload, the
default setting will be calculated first motor current IX overloaded for 30 minutes.
- 104 -
Chapter V Description of parameters
According to the motor overload graph, if the 30 - minute overload is within the current range of 125 % and
135 %, then it can be concluded that the 30 - minute overload motor current IX under the default setting is as follows:
(40-30)÷ (125%-Ix) = (40-15) ÷ (125%-135%)
The result shows that the motor current Ix = 129 %, so it can be concluded that the motor needs to overload for
30 minutes at 120 % of the motor current, and the motor overload protection gain:
F9-01=120%÷Ix=120%÷129%=0.93
Note: the user needs to set the value of F9 - 01 correctly according to the actual overload capacity of the
motor. If the parameter setting is too large, it is likely to cause overheating damage to the motor and the
frequency inverter does not give an alarm in time to protect it!
F9 - 02 motor overload warning coefficient
50%～100%[80%]
This function is used to give an early warning signal to the control system through do before motor overload fault
protection. This early warning coefficient is used to determine how much early warning is to be given before motor
overload protection. The higher the value, the smaller the advance warning amount
When the frequency inverter output current accumulation is greater than the product of the overload inverse time
limit curve and F9 - 02, the multi-function digital word DO of the frequency inverter outputs the “motor overload
pre-alarm" on signal
F9 - 03 Over voltage stall gain
0～100 [0]
F9 - 04 stall over voltage point
120%～150% [130%]
F9 - 03 = 0: Over voltage stall protection function is invalid.
F9 - 03 non - 0: Over voltage stall protection function is valid.
During the speed reduction of the frequency inverter, due to the influence of the load inertia, the actual decrease
of the motor speed may be lower than the decrease rate of the output frequency. At this time, the motor will feed back
electric energy to the frequency inverter, causing the voltage of the DC bus of the frequency inverter to rise. If no
measures are taken, an Over voltage fault will occur.
The over-voltage stall protection function detects the bus voltage during the deceleration operation of the
frequency inverter, and compares it with the F9 - 04 * 534 v stall Over voltage point. If the stall voltage is exceeded,
the frequency output of the frequency inverter stops falling. When the bus voltage is lower than the stall Over voltage
point, the deceleration operation will be implemented again.
F9 - 03 the greater the Over voltage stall gain setting, the stronger the ability to suppress Over voltage. However,
on the premise that no over voltage occurs, the smaller the benefit increase setting is, the better.
For loads with small inertia, the over-pressure stall gain should be small; otherwise the system's dynamic
response will slow down.
For large inertia loads, this value should be large; otherwise, the suppression effect is not good and Over voltage
faults may occur.

Chapter V Description of parameters
F9 - 05 over loss rate gain

F9 - 06 stall flow point
100%～200% [150%]
Over current speed: when the frequency inverter output current reaches the set over current stall protection
current (F9 - 06), the frequency inverter will reduce the output frequency when accelerating operation; Reduce the
output frequency during constant speed operation; During deceleration operation, the speed of descent is slowed
down until the current is less than the over current stall protection current (F9 - 06) before the operating frequency
returns to normal.
Over current stall protection current: select the current protection point with over current speed function. The
frequency inverter starts to perform over-current stall protection function beyond this parameter value. This value is
the percentage of the rated current of the motor.
Over - loss speed gain: used to adjust the frequency inverter's ability to suppress over-current during
acceleration and deceleration. The greater the value, the stronger the ability to suppress over current on the premise
of no over current, and the smaller the gain setting, the better.
For loads with small inertia, the over-loss rate gain should be small; otherwise the system's dynamic response
will slow down.
For loads with large inertia, this value should be large; otherwise, the suppression effect is not good and over
current faults may occur.
When the inertia is very small, it is recommended to set the over current suppression gain to less than 20. The
over-run speed gain is set to 0, the over-run speed function will be cancelled.

FC Group multi-segment instruction and simple PLC function
HV480 multi-segment instruction has more abundant functions than usual multi-segment speed. Besides
realizing multi-segment speed function, it can also be used as a voltage source for VF separation and a given source
for process PID. For this reason, the dimension of the multi-segment instruction is a relative value.
The simple PLC function is a multi-section speed generator. The frequency inverter automatically numbers the
running frequency and direction according to the running time to meet the technological requirements. The function
was previously completed by the PLC (programmable controller) and now depends on the frequency inverter.As
shown in figure 5 - 31.

Multi-segment instruction can be used in three situations: multi-segment speed as frequency source, simple
PLC, voltage source as VF separation, and setting source of process PID.
In the three applications, the dimension of the multi-segment instruction is the relative value,
ranging from -
100.0 % to 100.0 %.
Which is the percentage of the relative maximum frequency when used as the frequency source.
When VF is used as a separate voltage source, it is a percentage of the rated voltage of the motor.
Given the relative value of PID, multi-segment instructions as the PID setting source do not require dimensional
conversion.
The multi-segment instructions need to be switched and selected according to different States of the
multi-function digital X terminal,please refer to F5 group for details relevant instructions.
