Description
Troubleshooting and Maintenance
Possible Causes
Verify the network master status, making sure it is in execution
mode (Run).
Refer to the Profibus DP communication manual for more
information.
Verify whether the network master is correctly configured and
operating normally.
Verify the network installation in a general manner – cable
routing, grounding.
Refer to the Profibus DP communication manual for more
information.
Verify whether the Profibus DP module is correctly fit into the
slot 3.
Refer to the Profibus DP communication manual for more
information.
Wrong settings of P0161 and/or P0162.
Problem with the hoist-type load.
Defective FLASH memory module.
Check the connection of the FLASH memory module.
