PE6000 User Manual Description of Function Codes
93
To achieve a faster system response, 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.
Note
Improper PI parameter setting may cause too large speed overshoot, and overvoltage fault
may even occur when the overshoot drops.

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.

In the vector control mode, the output of the speed loop regulator is torque current reference.
This parameter is used to filter the torque references. It need not be adjusted generally and can be
increased in the case of large speed fluctuation. In the case of motor oscillation, decrease the value
of this parameter properly.
If the value of this parameter is small, the output torque of the AC drive may fluctuate greatly,
but the response is quick.
