9.4.57 WARNING 59, Current Limit
Cause
The current is higher than the value in parameter 4-18 Current Limit.
Troubleshooting
•
Ensure that the motor data in parameters 1-20 to 1-25 is set correctly.
• Increase the current limit if necessary. Ensure that the system can operate safely at a higher limit.
9.4.58 ALARM 60, External Interlock
Cause
A digital input signal indicates a fault condition external to the drive. Within the control compartment, the following 3 relay con-
tacts are connected in series to 1 digital input that is used as a thermal overload relay:
• KFJ.1 monitors the heat within the input power options cabinet.
• KFJ.2 monitors the heat within the output filter cabinet.
• KFJ.3 monitors the heat within the input filter cabinet.
When the thermal switches in any of these cabinets open due to overtemperature, the drive trips on External Interlock [A60].
Troubleshooting
• Open the control compartment and check for any lights in relays KFJ.1, KFJ.2, and KFJ.3. If no lights are present, check for other
external interlocks.
• Clear the external fault condition.
• To resume normal operation, apply 24 V DC to the terminal programmed for external interlock.
• Reset the drive.
