Select which frequency converter input should be treated as the source of the first of these signals. The second
input signal is defined in par. 7-22.
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 signal.
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 frequency cannot be increased or decreased.
Function:
Enter the motor speed to be attained as a start signal for commencement of PID control. When the power is
switched on, the frequency converter will commence ramping and then operate under speed open loop control.
Thereafter, when the Process PID start speed is reached, the frequency converter will change over to Process
PID control.
