None System fault : Fault Trouble Quick stop by trouble Warning locked ; Warning Information
Cause
Remedy
The signals of the connected encoder of the motor
temperature detection (resolver at X7 or encoder at X8)
are outside the defined operating range of detection.
• Check bonding of the encoder cable at the motor and
controller.
• Check selection of the motor temperature sensor in
and make sure that it complies with the
assembly in the motor.
• Possibly switch off temperature sensor monitoring
(
="0").
• If a PTC is in the motor, activate the monitoring of the
