Error behaviour
r When the stop position of the motor axis has changed during the brake test by more
than the permissible angle of rotation set in C02595
despite the applied brake:
The brake test is aborted immediately and the controller is inhibited.
The status "position drift when brake is applied" is displayed at the status output
BRK_dnState via bit 21 and the status "brake error" is displayed via bit 15.
The output BRK_bError is set to TRUE.
r By resetting the input BRK_bBrakeTest to FALSE an error can be reset automatically.
