14.1 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.
Additional information on parameterization can be found in the MOVIMOT
®
inverter
operating instructions.
Please also refer to the information on voltage supply in chapter " Installation instruc-
tions for fieldbus interfaces, field distributors" (→
2
35).
Step 1: Check the connection between the inverter and EtherCAT
®
Are the bus plugs properly plugged in the master and EtherCAT
®
interface?
NO → [A]
YES
↓
What are the "L/A" LEDs on the EtherCAT
®
interface doing? OFF → [A]
ON
↓
Is the EtherCAT
®
interface physically connected to the EtherCAT
®
properly? Check the EtherCAT
®
connection at X11 IN (EtherCAT
®
incoming) and X12 OUT (EtherCAT
®
outgoing).
NO →
[A]
YES
↓
Continue with 2: What is the "RUN" LED doing?
[A] Check the bus cabling.
Step 2: What is the "RUN" LED doing?
