InverterFR-A800Verification pending — cross-check with the official manual
FR-A800 E.PID — PID signal fault
Trip — immediate stop
CAUSE
Why does it occur?
- The inverter output is shut off if the measured value exceeds the PID upper limit or PID lower limit parameter setting, or the absolute deviation value exceeds the PID deviation parameter setting during PID control
- Set this function in Pr.131 PID upper limit, Pr.132 PID lower limit, Pr.553 PID devi
REMEDY · Step by step
How to fix it?
• Check that the meter has no failure or break. • Set the parameters correctly.
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.).
