Error Code C3h on Linmot control unit and BF LED on PLC red

Possible cause:
– bus connector limit switch not set correctly – address and dip switches not set according

to the electrical scheme (bus subscriber). – wire defect
– bus connector defect
– bus modul or subscriber defect.

 

To narrow the error you have to check the status with all the subscribers.
To test, 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.

If you are able to narrow in the error, exchange the corresponding components.

 

NOTE:
Do not forget to set the parameter and the dip switches accordingly. The parameters are mentioned in the electrical scheme!

 

BF LED (red) not aktiv

Lenze inverter:
LED upper left must light up (green)
LED upper right must be flashing (yellow)

LinMot:
Error LED not aktiv or no error code profibus
