Description:
Sets the signal source to activate the armature short-circuit or DC brake.
Dependency:
Refer to: p1231, p1232, p1233, p1234, p1235, p1236, p1237, r1238, r1239
Note:
1 signal: Armature short-circuit/DC brake is deactivated.
0 signal: Armature short-circuit/DC brake is deactivated.
Description:
Setting to activate various types of armature short-circuit configurations / DC brake.
Values:
0:
No function
1:
External armature short-circuit with contactor feedback signal
2:
Ext. armature short-circuit without contactor feedback signal
3:
Internal voltage protection
4:
Internal armature short-circuit / DC brake
Dependency:
Refer to: p0300, p1230, p1232, p1233, p1234, p1235, p1236, p1237, r1238, r1239
Danger:
Re p1231 = 1, 2:
- only short-circuit proof motors may be used and suitable resistors must be used to short-circuit the motor.
Re p1231 = 3:
- when the internal voltage protection is active, after pulse cancelation, all of the motor terminals are at half of the
DC link voltage (without an internal voltage protection, the motor terminals are at zero potential)!
- it is only permissible to use motors that are short-circuit proof (p0320 < p0323).
- the Motor Module must be able to continually conduct 180% short-circuit current (r0331) of the motor (r0289).
- the internal voltage protection cannot be interrupted due to a fault response. If an overcurrent condition occurs
during the active, internal voltage protection, then this can destroy the Motor Module and/or the motor.
- if the Motor Module does not support the autonomous, internal voltage protection (r0192.10 = 0), in order to
ensure safe, reliable functioning when the line supply fails, an external 24 V power supply (UPS) must be used for
the components.
- if the Motor Module does support the autonomous, internal voltage protection (r0192.10 = 1), in order to ensure
safe, reliable functioning when the line supply fails, the 24 V power supply for the components must be provided
through a Control Supply Module.
- if the internal voltage protection is active, it is not permissible that the motor is driven by the load for a longer
period of time (e.g. as a result of loads that move the motor or another coupled motor).
Re p1231 = 4:
- Synchronous motors (p0300 = 2xx, 4xx) must be short-circuit proof (p0320 < p0323).
Note:
Re p1231 = 1, 2:
The external armature short-circuit can only be selected for synchronous motors (p0300). In this case, control bit
BO: r1239.0 must be interconnected to control the external contactor (e.g. to a digital input).
