Freeze field current setpoint operating mode / If freeze op_mode

DC_CTRL Can be changed: U, T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets the operating mode for the "Freeze field current setpoint" function.
Value: 0:
1:
2:
Notice: For settings 0 and 1, when a fault message occurs, the EMF control remains active.
Even if the speed sensing is faulted or if the contactor on the DC side is open.
In these cases, the EMF controller cannot prevent overvoltages occurring at the motor.
As a consequence, measures must be ensured on the system side that ensure that the motor is not damaged by
overvoltages.
p50272

Field current reduction activation / I_field_red act

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets activation/de-activation of automatic field current reduction if the EMF is too high for braking operation.
Value: 0:
1:
Dependency: Refer to: F60043, A60143
Note: If value = 0:
If the EMF is too high for braking operation, a message is output accordingly.
p50273[0...n]

EMF controller pre-control activation / EMF ctr prec act

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets activation/de-activation for EMF controller pre-control.
Value: 0:
1:
Note: If value = 0:
The EMF controller's pre-control output is set to 100% (corresponding to the rated excitation current of the motor
(p50102)).
p50274[0...n]

EMF controller integral component activation / EMF ctr I comp act

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets activation/de-activation of the integral component on the EMF controller.
