What can cause a Load Slipping (ANF) fault on an ATV340 series drive?
Issue:
ATV340 drive shuts down with ANF Load Slipping Fault.
Product Line:
ATV340 series
Environment:
In applications using an encoder
Cause:
The difference between the output frequency and the speed feedback is not correct.
Resolution:
If the torque control function is used and if the encoder is assigned to speed feedback:
ATV340 drive shuts down with ANF Load Slipping Fault.
Product Line:
ATV340 series
Environment:
In applications using an encoder
Cause:
The difference between the output frequency and the speed feedback is not correct.
Resolution:
- Confirm the drive rating according to the application (motor, load, and so on.)
- Verify the motor, gain, and stability parameters.
- Add a braking resistor.
- Verify the mechanical coupling and wiring of the encoder.
If the torque control function is used and if the encoder is assigned to speed feedback:
- Set [Load slip detection] Sdd = [No] no.
- Set both [Positive deadband] dbp and [Negative deadband] dbn to a value less than 10% of the nominal motor frequency.
