Armature gating unit short pulses/long pulses / Arm sh/lg pulse

DC_CTRL
Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description:
Sets the short pulses/long pulses on the armature gating unit.
Value = 0:
The gating unit emits short pulses (0.89 ms = approx. 16 degrees at 50 Hz).
Value = 1:
The gating unit emits long pulses (pulse duration up to approx. 0.1 ms before the next pulse) (e.g. required in the
case of field infeed from the armature terminals).
Value:
0:

Brake control braking mode / Brake ctr mode

DC_CTRL
Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description:
Sets the braking mode for brake control.
Value:
0:
1:
2:
Dependency:
Refer to: p50370, p50371
Note:
If p50080 = 1 (holding brake):
If the "Enable operation" command is withdrawn or the "Disconnect voltage" or "E-stop" command is set, the "Close
brake" command will not be set until "n < n_min" is reached.
If p50080 = 2 (operational brake):
If the "Enable operation" command is withdrawn or the "Disconnect voltage" or "E-stop" command is set, the "Close
brake" command will be set immediately (in other words, even if the motor is still running).
p50081

Field weakening activation / Field weak act

DC_CTRL
Can be changed: C2(1), T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description:
Sets the activation/de-activation of EMF-dependent field weakening.
Value:
0:
1:
Notice:
When field weakening is active (p50081 = 1), a valid field characteristic must be available (p50117 = 1); if not, the
optimization run for field weakening (p50051 = 27) must be performed.
