6 Troubleshooting
6.1 Product not turning
Corrective action
Check the supply lines for defects.
Check electrical connection.
} 5.2.3 [/ 81]
Check the settings of the drive controller.
DANGER Risk of fatal injuries due to electric shock!
Check whether there is voltage at the drive controller's
output.
If there is no voltage:
Check connection assignment, see drive controller
operating manual.
} 5.2.3 [/ 81]
Check communication.
Check mechanics.
Check that the mounting surface is flat.
} 5.2.1 [/ 76]
Check encoder and encoder connection.
If defective:
Replace component or send it to SCHUNK for repair.
For encoders with safety functionality, see "Safety
Manual MSAC200ERT-DQ V01.00".
Check terminal resistances with a multimeter.

If the difference between the individual motor phases
is larger than 0.1 Ohm:
Replace component or send it to SCHUNK for repair.
Check protective conductor.
If the product has a ground leak while the power cable
is disconnected:
Check the electrical connections and connectors for
ground leakage.
Replace component or send it to SCHUNK for repair.
Check electrical connection.
