Phase loss protection (orP)
When DC bus ripple is higher than the protection level, and the output current exceeds 50% of the rated current, the drive starts counting. When the counting value reaches the upper limit, an orP error occurs.
Check input supply & input phase.
Check drive rectifier using multimeter.
