Function:
Enter the low reference value [RPM] for the motor shaft speed. This is also the low feedback value,
Term. 29 Low Ref./Feedb. Value
see also par. 5-52
Function:
Enter the high reference value [RPM] for the motor shaft speed. See also par. 5-53
Ref./Feedb. Value .
Function:
Enter the pulse filter time constant. The low-pass filter reduces the influence on and dampens os-
cillations on the feedback signal from the control.
This is an advantage, e.g. if there is a great amount on noise in the system. This parameter cannot
be adjusted while the motor is running.
