Re p1231 = 3:
The internal voltage protection (using an internal armature short-circuit) can only be selected for synchronous
motors (p0300) and Motor Modules in booksize format. Further, it is not permissible that Safety is active (i.e. p9501
= 0 and p9601 = 0). The internal voltage protection prevents the DC link capacitance from being charged if there is
no possibility of regenerating the EMF of a motor operated in the field-weakening mode. The Motor Module must
support this function (r0192.9 = 1).
a) If the Motor Module does not support the autonomous, internal armature short-circuit (r0192.10 = 0), the arma-
ture short-circuit is activated as soon as the activation criterion is fulfilled (refer below):
b) If the Motor Module supports the autonomous internal voltage protection (r0192.10 = 1), then the Motor Module
automatically decides - using the DC link voltage - as to whether the short-circuit should be activated. In this case,
protection is also provided even if the DRIVE-CLiQ connection between the Control Unit and Motor Module was
interrupted. The short circuit is activated if the DC link voltage exceeds 800 V. If the DC link voltage falls below 450
V, then the short-circuit is withdrawn. This therefore ensures that the required input voltage for the Control Supply
Module is maintained.
Re p1231 = 4:
The function is activated as soon as the activation criteria is fulfilled.
- the function can be initiated by an OFF2 response.
a) for synchronous motors (p0300 = 2xx, 4xx), the internal armature short-circuit is initiated.
- the Motor Module must support this function (r0192.9 = 1).
b) for induction motors (p0300 = 1xx), the DC brake is initiated.
Activation criteria (one of the following criteria is fulfilled):
- the signal at BI: p1230 (DC brake activation) is 1.
- the drive is not in the state "S4: Operation" or in S5x (refer to function chart 2610).
- the internal pulse enable is missing (r0046.19 = 0).

DC Brake
Description: Sets the braking current for DC braking.
Dependency: Refer to: p1230, p1231, p1233, p1234, r1239
Note: A change to the braking current becomes effective the next time that the DC brake is powered-up.
Description: Sets the braking current for DC braking.
Dependency: Refer to: p1230, p1231, p1233, p1234, r1239, p1345, p1346
Note: A change to the braking current becomes effective the next time that the DC brake is powered-up.
For the current controller, the settings of parameters p1345 and p1346 (Imax limiting controller) are used.
