Error: The LED “SF” and “BF” of the PLC are “red”
- No supply of a slave on the bus system.
- Check supply of all slaves.
Emergency stop must be released.
- Address of slave on Profibus is wrongly adjusted.
- Check setting of all DIP switches on the Lenze bus module and on the Linmot controller.
You can find the correct setting on the wiring diagram.
- Wrong position of the switch for end resistant on the bus plug.
- Check all switches on the complete bus system. Seriously follow the cable from PLC to the last slave. First plug and plug of last slave must be set to ON, all other plugs to OFF.
