InverterFR-A800Verification pending — cross-check with the official manual
FR-A800 E.CTE — Circuit fault
Critical — power cycle required
CAUSE
Why does it occur?
- • When the power supply for the operation panel (PU connector) is shorted, the power output is shutoff and the inverter output is shut off
- The use of the operation panel (parameter unit) and the RS-485 communication via the PU connector are disabled
- To reset, enter the RES signal from the terminal
REMEDY · Step by step
How to fix it?
• Check PU and the cable. • Check the connection of the RS-485 terminals.
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.).
