7-08 Speed PID Feed Forward Factor
Range: Function:
0 %* [0 - 500 %] 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
Range: Function:
300 RPM* [10 - 100000
RPM]
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 will be corrected via
ramping in a controlled way.
