Faults and AlarmsIssue 01/06
F0452 Load torque fault detected | STOP II |
Quit
Refer to F0001
Cause
-load conditions at the motor signify a load torque fault (e.g. belt failure) or a mechanical fault
Diagnosis & Remedy
Please check the following:
-no braking, failure or destruction of the mechanical drive transmission line
-if required, lubricate the mechanical drive transmission line.
If you are using an external encoder, please check the following parameter settings:
-P2192 (delay time, load torque monitoring)
If you are operating within a specific speed range, please check the following:
-P2182 (load torque monitoring F1)
-P2183 (load torque monitoring F1f2)
-P2184 (load torque monitoring F1f3)
-P2185 (upper torque threshold 1)
-P2186 (lower torque threshold 1)
-P2187 (upper torque threshold 2)
-P2188 (lower torque threshold 2)
-P2189 (upper torque threshold 3)
-P2190 (lower torque threshold 3)
-P2192 (delay time, load torque monitoring)
F0453 Motor stalled | STOP II |
Quit
Refer to F0001
Cause
-up/ or down ramp too steep (excessive gradient)
-inverter connected to an already spinning motor without using the flying restart function
-motor incorrectly connected
-motor too small
-voltage boost P1611 for sensorless vector control too low
Diagnosis & Remedy
Please check the following:
-the motor connections
-increase the
-activate the flying restart function P1200
-use a larger motor
-increase the voltage boost P1611 for sensorless
-use
-activate the V/f
