PowerFlex 525 F064: Drive Overload
What F064 means
The drive's own overload rating was exceeded: the drive, not just the motor, carried too much current for too long.
Symptoms
Trips under heavy load or long, hard accelerations.
Is it repairable?
Usually an application issue; if the drive trips at light load, its current sensing may be faulty and can be repaired.
Common causes
- Drive undersized for the application
- Mechanical load too heavy
- Acceleration time too short
Safe checks
- 1Compare output current with the drive rating
- 2Lengthen the accel time
- 3Check the machine for binding
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
