Extended Current Controller; Torque Controller - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

17.5.2 Extended Current Controller

For some machines it might be necessary, that for different current ranges different
Amplification factors must be set up.
The following classification applies:
•
Current <
•
Current above P. 700 is in effect
>
•
Current >
rent
By default, the parameters are pre-assigned so that the parameters are not active
and only the basic parameters are active.
No.
757 Current below P. 700 is in effect
758 Current above P. 759 is in effect
759 Amplification high Current
775 Current above P. 700 is in effect
776 Current below P. 777 is in effect
777 Amplification low Current
I = Nominal Output current of Frequency inverter
FIN
o: Overload capability of Frequency inverter
The motor autotuning changes the parameters.

17.5.3 Torque Controller

The torque-controlled configurations 230, 430, 530 and 630 can be used for sensor-
less torque control alternative to the speed control. The torque control is usable
above the
sion is active with the current reference frequency as reference value. In this case
the torque is not controlled, but results depending on the load and the
623. To achieve a starting in torque control, the reference frequency should be
