VLT AutomationDrive FC 301/302
Programming Guide
Parameter 2-32 Speed PID Start Integral Time
Table 180: Parameter 2-32 Speed PID Start Integral Time
2-32 Speed PID Start Integral Time
Default value: 20.0 ms
Conversion index: -4
Enter the speed controller integral time. Obtain quick control through a short integral time, though if the integral time is too short,
the process becomes unstable. An excessively long integral time disables the integral action.
Parameter 2-33 Speed PID Start Lowpass Filter Time
Table 181: Parameter 2-33 Speed PID Start Lowpass Filter Time
2-33 Speed PID Start Lowpass Filter Time
Default value: 2.0 ms
Conversion index: -4
Set a time constant for the speed control low-pass filter. The low-pass filter improves steady-state performance and dampens oscil-
lations on the feedback signal. However, severe filtering can be detrimental to dynamic performance.
Parameter 2-34 Zero Speed Position P Proportional Gain
Table 182: Parameter 2-34 Zero Speed Position P Proportional Gain
2-34 Zero Speed Position P Proportional Gain
Default value: 0.0000
Conversion index: -4
This parameter is only available with software version 48.XX.
Enter the proportional gain for position control at standstill in speed mode.
5.4 Parameter Group 3-** Reference/Ramps
Parameters for handling of reference, definition of limitations, and configuration of the reaction of the drive to changes.
5.4.1 3-0* Reference Limits
Parameter 3-00 Reference Range
Table 183: Parameter 3-00 Reference Range
3-00 Reference Range
Default value: Size related
Conversion index: –
Select the range of the reference signal and the feedback signal. Signal values can be positive only, or positive and negative. The
minimum limit may have a negative value, unless [1] Speed closed loop control or [3] Process is selected in parameter 1-00 Configura-
tion Mode.
