Periodically use a megger to check for ground faults between phases (U, V, W). A reading of 300 M Ωcap omega or more is typically considered healthy.

Wiring Precautions: High-voltage power cables must be separated from feedback signal cables (encoders) to prevent electromagnetic interference (EMI). Troubleshooting and Fault Diagnosis

The Safety Precautions section of B‑65412EN distinguishes between (risk of injury) and Cautions (risk of equipment damage) and stresses that operations not specifically described in the manual should be considered impossible unless you have explicit FANUC approval. b 65412 fanuc
