Motor
Par 7-07=1.00
Function:
[0 - 500 %] The reference signal bypasses the speed
controller by the amount specified. This
feature increases the dynamic performance
of the speed control loop.
Function:
[10 - 100000 The speed error between ramp and
*
RPM] 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.
