4 PROFIBUS-DP Option Components
Solution
Check all wiring to the drive, then turn the power
on
• Shut the drive off and check that the PROFIBUS
DP Option is properly connected
• Turn the power back on again
–
Cycle power to the drive. If the LED status does
not change, replace the PROFIBUS-DP Option
• 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
• Check that the data lines are properly connected
to the drive
• Check the communication procedure settings in
the master
