Phase loss protection (orP)
Phase loss of power input - 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
Phase loss of input power - Correctly install the wiring of the main circuit power.
Check input supply if input supply is ok then check rectifier using multimeter.
