2.2 List of parameters
Re index 0:
Only values less than r50071 can be set.
Re index 1:
Only values less than r50074 can be set.
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: Short pulses
1: Long pulses
Description: Sets the braking mode for brake control.
Value: 0: No brake
1: Holding brake
2: Operational brake
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If the "Enable operation" command is withdrawn or the "Disconnect voltage" or "E-stop" command is set, the "Close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If the "Enable operation" command is withdrawn or the "Disconnect voltage" or "E-stop" command is set, the "Close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).
Description: Sets the activation/de-activation of EMF-dependent field weakening.
Value: 0: Deactivated
1: Activated
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.
