4 PROFIBUS-DP Option Components
Possible Cause
• Check all wiring to the drive, then turn the power on.
• Shut the drive off and see if the PROFIBUS-DP Option is
connected properly. Turn the power back on again.
• Cycle power to the drive. If the LED status does not change,
replace the PROFIBUS-DP Option.

• Check the node address setting in the drive (parameter F6-10).
• Check the network settings in the master
• Make sure the master device is operating normally
• Check the terminal resistance settings on the data line
• Look for any problems with the data line, or if the connector
