F07935 (N) Drive: Incorrect motor holding brake configuration

Message value: %1

Drive object: All objects

Reaction: NONE (OFF1, OFF2, OFF3)

Acknowledge: IMMEDIATELY

Cause: An incorrect motor holding brake configuration was detected.

Fault value (r0949, interpret decimal):

A motor holding brake was detected where the brake control has not been configured (p1215 = 0).

The brake control configuration was set to "motor holding brake the same as sequence control" (p1215 = 1) (only when

commissioning for the first time).

For a chassis unit with Safe Brake Adapter (SBA), the interconnection p9621 = r9872.3 was established (only when

commissioning for the first time).

For a parallel connection, the power unit was set in p7015, to which the motor holding brake is connected (only when

commissioning for the first time).

A motor holding brake was detected where the brake control has not been configured (p1215 = 0).

The brake control configuration was left at "No motor holding brake available" (p1215 = 0).

11:

The identification had detected more than one motor holding brake for a parallel connection.

12:

For the parallel connection, in p0121 there is no valid component number for the power unit data set that is set in p7015.

13:

With the "Safe brake control" (SBC) function activated, an attempt was made to change the value in p7015.

14:

For a parallel connection, the power units set in p7015 cannot be addressed.

Remedy: For fault value = 0:

- no remedy required.

For fault value = 1:

- if required change the motor holding brake configuration (p1215 = 1, 2).

- if this fault value unexpectedly occurs, then the motor connections should be checked in order to rule out that they have

been interchanged.

For fault value = 11:

For a parallel connection, only connect one motor holding brake.

For fault value = 12:

Check the setting of the power unit data set for a parallel connection (p7015).

For fault value = 13:

Before changing p7015, deactivate the "Safe brake control" function (SBC) (p9602).

For fault value = 14:

Check whether the power unit supports the brake control for a parallel connection (r9771.14).

Check whether there is a DRIVE-CLiQ communication error between the Control Unit and the power unit involved and, if

required, carry out a diagnostics routine for the faults identified.
