PowerFlex VFD Fault F007 — Motor Overload

PowerFlex drive electronic motor overload protection tripped. The drive calculated that motor current exceeded the thermal model limits based on motor nameplate data programmed in the drive.

Probable Causes (ranked)

• Mechanical overload on driven equipment — jammed product, seized bearing, or excessive friction
• Motor nameplate data entered incorrectly in drive — FLA, service factor, or motor type wrong
• Motor overload protection parameters set too aggressively for the application
• Motor cooling compromised — fan failure on motor or running at low speed without external cooling
• Motor is undersized for the application — continuous current draw near or above nameplate FLA

Fix Steps

1. 1 Check motor current draw with clamp meter — compare to motor nameplate FLA
2. 2 Inspect driven equipment for mechanical binding — try to rotate by hand with motor disconnected
3. 3 Verify motor nameplate data in drive parameters — FLA (A091), Motor NP Volts (A089), Motor NP Hz (A090)
4. 4 Check motor cooling — verify fan spins when motor runs, clear any debris from air intake
5. 5 If motor runs at reduced speed via VFD, confirm external cooling fan is installed and operational
6. 6 Reset drive fault — monitor current during normal operation to establish baseline
7. 7 If motor is consistently at or above FLA, the motor may be undersized — evaluate upsizing motor or reducing load
