increase the proportional gain and reduce the integral time. Be aware that this may lead to system
oscillation.
The recommended adjustment method is as follows:
If the factory setting cannot meet the requirements, make proper adjustment. Increase the
proportional gain first to ensure that the system does not oscillate, and then reduce the integral time to
ensure that the system has quick response and small overshoot.
ATTENTION:
Improper PI parameter setting may cause too large speed overshoot, and overvoltage fault may
even occur when the overshoot drops.
F10.07
ASR input filtering time
Range:0.0
～
500.0ms
Default:3.0ms
F10.08
ASR output filtering time
Range:0.0
～
500.0ms
Default:0.0ms
Sets the input/output filtering time of ASR.No need to modify its default setting if not have special
requirement.
F10.09
Vector control slip gain
Range:50
～
200%
Default:100%
For SFVC, it is used to adjust speed stability accuracy of the motor. When the motor with load
runs at a very low speed, increase the value of this parameter; when the motor with load runs at a very
large speed, decrease the value of this parameter.
For CLVC, it is used to adjust the output current of the AC drive with same load.
F10.10
Digital setting of torque upper
limit in speed control mode
Range:50.0
～
200.0%
Default:165%
In the speed control mode, the maximum output torque of the AC drive is restricted by F10.10.
F10.11
Excitation adjustment
proportional gain Kp1
Range:0.00
～
10.00
Default:0.50
F10.12

～
3000.0ms
Default:10.0ms
F10.13
Torque adjustment
proportional gain Kp2
Range:0.00
～
10.00
Default:0.50
F10.14
Torque adjustment integral
gain Ti2
Range:0.0
～
3000.0ms
Default:10.0ms
These are current loop PI parameters for vector control. These parameters are automatically
obtained through "Asynchronous motor complete auto-tuning" or "Synchronous motor no-load
auto-tuning", and need not be modified.
F10.15
Excitation gain coefficient
Range: 50.0
～
200.0%
Default: 100.0%
For sensor-less vector control, the parameter is used to adjust the exciting current of the motor. When
the motor torque is low, the parameter is increased, otherwise the parameter is decreased. For speed
sensor vector control, this parameter can adjust the no-load excitation current of the motor.
F10.16
Torque setting source under
torque control
Range:0
～
6
Default:0
F10.17
Digital setting of torque
Range:-200
～
200%
Default:50.0%
F10.16 is used to set the torque setting source. There are a total of 6 torque setting sources.
The torque setting is a relative value. 100.0% corresponds to the AC drives rated torque. The
setting range is -200.0% to 200.0%, indicating the AC drive's maximum torque is twice of the AC
drive's rated torque.
If the torque setting is positive, the AC drive rotates in forward direction. If the torque setting is
negative, the AC drive rotates in reverse direction.
0: Digital setting (F10.17)
The target torque directly uses the value set in F10.17.
1: Keypad potentiometer
2: AI1
3: AI2
4: AI3
The target torque is decided by analog input.
5: Pulse setting (DI7/HI)
The target torque is set by DI7/HI (high-speed pulse). The pulse setting signal specification is
9–30 V (voltage range) and 0–100 kHz (frequency range). The pulse can only be input via DI7.
6: Communication setting
