9.1 Diagnostic procedures
The diagnostics procedures described in the following section demonstrate the fault
analysis methods for the following problems:
• Inverter does not operate on EtherCAT
®
• Inverter cannot be controlled using the EtherCAT
®
master.
For more information dealing specifically with the inverter parameter settings for various
fieldbus applications, refer to the "MOVIDRIVE
®
MDX60B/61B Communication and
Fieldbus Unit Profile" manual and the MOVIDRIVE
®
MDX60B/61B system manual.
Step 1: Check the connection between the inverter and EtherCAT
®
Step 2: Response of the RUN LED?

is connected correctly at X30 IN (incoming
EtherCAT
®
connection) / X31 OUT (outgoing EtherCAT
®
connection).
