Larger gain values result in faster response, but may result in less stability. If the drive
overshoots the speed reference when changes to the reference are made, or if the
drive is unstable, reduce the value.
With the default value, the drive should perform satisfactorily. However, with increased
inertia loads, this parameter may need to be adjusted.
The higher the gain is set in this parameter, the higher the performance of the torque
loop. If the gain is set too high, the drive will become more susceptible to overcurrent
trips and/or instability. Decreasing the gain will help to increase stability.
This parameter is not used when the drive is programmed for SVC operation.
U.013 Speed Regulator Integral Gain
This parameter
selects the lead
frequency of the PI
amplifier in the speed
loop. This value
affects the dynamic
performance of the
speed regulation of
the motor.
For most
applications, it is
recommended that
this parameter not be
adjusted.
Parameter Range: 0.02 to 327.67 radians/second
Default Setting: Power Module-dependent, see Appendix C
Parameter Type: Tunable
Refer also to parameters: N/A
U.014 Torque Regulator Proportional Gain
This parameter
determines the
performance of the
torque regulator.
For most
applications, it is
recommended that
this value not be
changed.
Parameter Range: 0.10 to 31.99
Default Setting: Power Module-dependent, see Appendix C
Parameter Type: Tunable
