Function:
Function:
controller by the amount specified. This
feature increases the dynamic performance of
the speed control loop.
Function:
torque controller. Selection of a high value
makes the controller react faster. Too high a
setting leads to controller instability.
Function:
Enter the integration time for the torque
controller. Selection of a low value
makes the controller react faster. Too
low a setting leads to control instability.
Function:
The effective feedback signal is made
up of the sum of up to two different
input signals.

3.9.4 7-3* Process PID Ctrl.
7-30 Process PID Normal/ Inverse Control
Option: Function:
Normal and inverse control are implemented by
introducing a difference between the reference
signal and the feedback signal.
[0] Normal Sets process control to increase the output frequen-

[1] Inverse Sets process control to reduce the output frequency.
7-31 Process PID Anti Windup
Option: Function:
[0] Off Ceases regulation of an error when the output frequency
can no longer be adjusted.
[1] On Continues regulation of an error even when the output
*
frequency cannot be increased or decreased.

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
