7-08 Speed PID Feed Forward Factor
Default value:
0%
Setup:
All setups
Data type:
Uint16
The reference signal bypasses the speed controller by the amount specified. This feature increases the dynamic performance of the
speed control loop.
7-09 Speed PID Error Correction w/ Ramp
Default value:
300 RPM
Setup:
All setups
Data type:
Uint32
Specify the speed error, between ramp and actual speed, which must be corrected by the ramp.
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.
