MG.33.M2.02 - VLT
Function:
The effective feedback signal is made up of the sum of up to
two different input signals. Select which frequency converter
input should be treated as the source of the second of these
signals. The first input signal is defined in par. 7-21.
Function:
Normal and inverse control are implemented by introducing a
difference between the reference signal and the feedback sig-
nal.
Sets process control to increase the output frequency.
Sets process control to reduce the output frequency.
Function:
Ceases regulation of an error when the output frequency can no
longer be adjusted.
Continues regulation of an error even when the output frequen-
cy cannot be increased or decreased.
