FR-A800 E.MP — MagnetPole Pos Fault
Trip — immediate stop
CAUSE
Why does it occur?
When the offset value between the PM motor home magnetic pole position and the home position of the encoder (position detector) is unknown, the protective circuit is activated to stop the inverter output. • Check that the encoder position tuning was performed. • Check that the encoder position tunin
REMEDY · Step by step
How to fix it?
- • Perform encoder position tuning with Pr.373 (Pr.8
- Encoder position tuning setting/status. (Refer to page 560.) • Remove the cause of the tuning error, and perform tuning again. (Refer to page 560.)
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
