Troubleshooting
No Communication with the Drive
If there is no communication with the drive, proceed with the following checks:
Check 1: Is the cabling correct?
Check that the red and green cables are connected
to the correct terminals as shown in the diagram
below. If the cables are crossed, no communication
is possible.

63 = RxD/TxD-N green cable
Check 2: Is the correct GSD file installed?
Download the correct GSD file from http://danfoss.com/drives. The GSD file name is da01040A.GSD.
Check 3: Is the bus connection terminated at both ends?
If not, terminate the bus connection with termination resistors at the initial and final nodes, as shown in
