Error Code C3h on Linmot control unit and BF LED on PLC red
Summary
Profibus connection or component failed.
Cause
- bus connector limit switch not set correctly
- address and dip switches not set accordingly to the electrical diagram (bus subscriber)
- wire defect
- bus connector defect
- bus module or subscriber defect
Remedy
- To narrow the error, you must check the status with all the subscribers.
- Switch the limit switch into the bus connector → the bus runs now to the corresponding subscriber, e.g. “Lenze inverter” which the LED flashes yellow.
Example: - Exchange the corresponding components.
NOTE: Do not forget to set the parameter and the dip switches accordingly. The parameters are mentioned in the electrical diagram!
