FR-E800 E.OA — Acceleration Error
Trip — immediate stop
CAUSE
Why does it occur?
- The acceleration error (E.OA) occurs and the inverter output is shut off when the acceleration rate of the motor rotation speed has exceeded the faulty acceleration rate detection level (Pr.375)
- This protective function is not available in the initial status. • Check for sudden load change. • Check that the Pr.375 Faulty acceleration rate detection level setting is correct. • Check if the acceler
REMEDY · Step by step
How to fix it?
- • Reduce the load. • Set Pr.375 Faulty acceleration rate detection level correctly. • If the acceleration/deceleration rate is great and an error occurs during normal operation, set Pr.375 to "9999 (no error detection)"

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.).
