Event 38: Temperature drive controller sensor
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
Surrounding temperatures too
high or too low
Check the surrounding temperature of the drive controller and adjust it to
the operating conditions of the drive controller if necessary
Too little air circulation in the
control cabinet
Check minimum clearance and adjust it if necessary
Defective or blocked fan
Switch on control unit supply; check that the fan starts and replace the
drive controller if necessary
Assembly protection film
Remove the assembly protection film
Wrong drive controller design
Check the design and change the drive controller type if necessary
Increased or reduced
mechanical friction
Check the service status of the mechanical system and service them if
necessary
Mechanical block
Check the output and remove the block if necessary
Short deceleration/
acceleration times
Check the actual current during the braking process using the scope
image (E00); reduce the deceleration and acceleration values if
necessary
Clock frequency too high
Check the utilization of the drive, taking into account derating and the
configured clock frequency (E20, B24); reduce the configured clock
frequency or replace the drive controller if necessary
