The maximum output frequency is the highest frequency allowed by the inverter, which is the benchmark for setting
acceleration and deceleration time, as shown in the figure fmax below. The basic operating frequency is the minimum
frequency corresponding to the highest voltage output by the inverter, which is generally the rated frequency of the motor,
as shown in the figure below. The maximum output voltage Vmax is the corresponding output voltage when the inverter
outputs the basic operating frequency, which is generally the rated voltage of the motor; Vmaxas shown in the following
figure; FH and FL are defined as upper limit frequency and lower limit frequency respectively, as shown in Figure 00-1:
Output voltage
Output frequency
Figure 00-1 Schematic diagram of voltage and frequency
Notes:
1. The maximum output frequency, upper limit frequency and lower limit frequency should be carefully set according to the
nameplate parameters and operating conditions of the actual controlled motor, otherwise the equipment may be damaged.
2. The limit range of upper frequency is valid for JOG operation, while the limit range of lower frequency is invalid for JOG
operation.
3. In addition to the upper limit frequency and the lower limit frequency, the output frequency of the inverter during
operation is also limited by the set values of parameters such as starting frequency, starting frequency of DC braking during
shutdown and jumping frequency.
4. The relationship among maximum output frequency, upper limit frequency and lower limit frequency is shown in the
above figure 00-1. Please pay attention to the order of magnitude when setting.
5. The upper and lower limit frequencies are used to limit the actual output frequency of the motor. If the set frequency is
higher than the upper limit frequency, it will run at the upper limit frequency; Run at the lower limit frequency if the set
frequency is lower than the lower limit frequency (the running state when the set frequency is lower than the lower limit
frequency is also related to the setting of function code 01.31); If the set frequency is less than the starting frequency, it will
run at zero frequency when starting.

The acceleration time refers to the time required for the inverter to accelerate from zero frequency to the maximum
output frequency, as shown in the figure below at t1. Deceleration time refers to the time required for the inverter to
decelerate from the maximum output frequency to zero frequency, t2 as shown in the figure below.
There are four groups of acceleration and deceleration time parameters of this series of inverters, and the acceleration and
deceleration time of the other three groups is defined in the function codes 01.13 ~ 01.18. The factory default acceleration
and deceleration time is determined by the model. If you want to select other acceleration and deceleration time groups,
please select them through the multi-function terminal (please refer to the function codes 07.00 ~ 07.06). The acceleration
and deceleration time of JOG operation are defined separately in 01.22 and 01.23.

When this mode is selected, the actual output phase sequence of the inverter is consistent with the default phase
sequence of the system. At this time, the keys RUN
on the panel and FWD terminal functions become forward
control.
1: Reverse direction
When this mode is selected, the actual output phase sequence of the inverter will be opposite to the default phase
sequence of the system. At this time, the functions of keys RUN
and FWD terminals on the panel are changed to
reverse control.
2. Forbidden reverse operation
In any case, the motor can only run forward. This function is suitable for situations where reverse operation may bring
danger or property loss. Given the reverse command, the inverter runs at zero speed.
Tips
This function code setting is valid for running direction control of all running command channels.

This function code is used to set the carrier frequency of PWM wave output by inverter. The carrier frequency will affect
the noise when the motor is running, and the carrier frequency can be appropriately increased to meet the requirements
when silent operation is required. However, increasing the carrier frequency will increase the calorific value of the inverter
and the electromagnetic interference to the outside world.
When the carrier frequency exceeds the factory set value, the inverter needs to be derated. Generally, the inverter
current needs to be derated by about 5% for every 1KHz increase of download wave.

Starting frequency refers to the initial frequency when the inverter starts. As shown in the figure fs below, for some
systems with large starting torque, setting reasonable starting frequency can validly overcome the problem of starting
difficulty. The starting frequency holding time refers to the time that the inverter keeps running at the starting frequency
during the starting process, as shown in the figure below at t1. Schematic diagram of startup frequency is as follows:

Tips
1、The start frequency is not limited by the lower limit frequency. The JOG frequency is not limited by the lower limit
frequency but is limited by the starting frequency.

The relationship between output frequency and time increases or decreases according to a constant slope, as shown

The relationship between output frequency and time increases or decreases according to the S-shaped curve. When
acceleration starts and speed arrives, and when deceleration starts and speed arrives, the speed set value is in the
S-shaped curve state. This can make acceleration and deceleration smooth and reduce the impact on the load. S-curve
acceleration and deceleration mode is suitable for the start and stop of transporting and transferring loads, such as
elevators and conveyor belts. As shown in the figure below: t1 is acceleration time, t2 is deceleration time, ts is start time of

After receiving the shutdown command, the inverter gradually reduces the output frequency according to the
deceleration time, and stops after the frequency drops to zero. If the shutdown DC braking function is valid, the DC braking
process will be executed after reaching the shutdown DC braking start frequency (according to 01.09 setting, a shutdown
DC braking waiting time may be required), and then the shutdown will be performed.
1 Free stop
After receiving the shutdown command, the inverter immediately terminates the output, and the load stops freely

The above function codes are functions set to make the output frequency of inverter avoid the resonance frequency
point of mechanical load. The set frequency of the inverter can be given by jumping near some frequency points according
to the following figure. Its specific meaning is that the frequency of the inverter will never run stably within the jumping
frequency range, but will pass through this range during acceleration and deceleration.

automatically updated to the default parameters of asynchronous motor with corresponding power (02.02 is the rated

2. No-load Complete tuning
The complete parameter measurement mode of the motor is adopted as far as possible when the motor can be
separated from the load.
Tips
1When 02.16 is set to 2, if there is over current and tuning fault during tuning, It is necessary to check whether the output
is out of phase and whether the models match
2When 02.16 is set to 2, When complete tuning is carried out, the motor shaft should be separated from the load, and the
complete tuning of the motor with load is prohibited;
3Before starting the motor parameter tuning, make sure that the motor is in a stopped state, otherwise the tuning cannot
be performed normally.
4In some occasions (such as the motor can not be separated from the load, etc.), when complete tuning is inconvenient or
the user has low requirements for motor control performance, static tuning can be performed.
5If tuning is impossible and the user already knows the accurate motor parameters, the user can directly input the motor
nameplate parameters (02.01 ~ 02.14), and the superior performance of the inverter can still be exerted. The tuning is
unsuccessful, protect the action and display E-21.

Tips
The corresponding relationship between analog feedback channel voltage and actual voltage from 06.06 to 06.11 is
uniquely determined by the voltage transmitter (PT), and its calculation method is as follows:
Assume that U * = 120% * Ue = 456 V (AI1 setting )
PT transformation ratio =50 (input AC 0-500V, output DC 0-10V)
Then when the output reaches to the target voltage of 456V, the feedback voltage of PT output is
456/50V=9.12V
When the upper limit input of AI1 is 10V, the determined input voltage is 500V, and the ratio relative to the rated voltage is
500/380=132%
Therefore, 06.09(AI2 input upper limit voltage) is set to 10.00V, and 06.10(AI2 upper limit corresponding setting) is set to
132%.

mainly applied to the design of some variable frequency’s power supplies.
