Event 42: TempBrakeRes
The drive controller is interrupted if:
§
A29 = 0: Inactive for STOBER device controller
or
§
A540 = 0: disable drive, motor is free to rotate for CiA device controller
Response:
§
The power unit is disabled and axis movement is no longer controlled by the drive controller
§
The brakes are no longer controlled by the drive controller and engage in the event of an inactive release override
(F06)
The drive controller is interrupted with a quick stop if:
§
A29 = 1: Active for STOBER device controller
or
§
A540 = 2: slow down on quick stop ramp for CiA device controller
Response:
§
The axis is stopped by a quick stop; meanwhile, the brakes are controlled by the drive controller and remain released
§
At the end of the quick stop, the power unit is disabled and axis movement is no longer controlled by the drive
controller; the brakes are no longer controlled by the drive controller and engage in the event of an inactive release
override (F06)
Cause
Check and action
Short deceleration/acceleration
times
Check the DC link voltage during the braking process using the scope image (E03);
reduce the deceleration and acceleration values if necessary
Braking resistor too low
Check that the maximum permitted braking resistor power loss is suitable for the
application and replace the braking resistor if necessary
Brake chopper is defective
Check DC link voltage during the braking process using the scope image (E03); the
brake chopper is defective if E03 exceeds the on limit of the brake chopper R31
without E03 dropping; replace the drive controller if necessary
