F0071 fault in WEG CFW701 Drive indicates an Output Overcurrent. This means the inverter supplied excessive current, often due to high load inertia or aggressive acceleration.
Cause:
- Excessive load inertia or too short acceleration ramp.
- Parameters P0135, or P0169 and P0170 settings are too high.
Remedy:
Adjust acceleration ramp to be longer, or reduce load inertia. Adjust parameters P0135, P0169, and P0170.
