Parameter 7-08 Speed PID Feed Forward Factor
Table 455: Parameter 7-08 Speed PID Feed Forward Factor
7-08 Speed PID Feed Forward Factor
Default value: 0%
Parameter type: Range, 0 - 500%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: False
The reference signal bypasses the speed controller by the amount specified. This feature increases the dynamic performance of the
speed control loop.
Parameter 7-09 Speed PID Error Correction w/Ramp
Table 456: Parameter 7-09 Speed PID Error Correction w/Ramp
7-09 Speed PID Error Correction w/Ramp
Default value: Size related
Parameter type: Range, 10 - 100000 RPM
Setup: All setups
Conversion index: 67
Data type: Uint32
Change during operation: True
The speed error between ramp and actual speed is held up against the setting in this parameter. If the speed error exceeds this
parameter entry, the speed error is corrected via ramping in a controlled way.
