When the device is in IDLE mode and you send a start command, but the device does not start to charge within the adjusted energy saving timeout [idLt] (Factory settings: 5s // 8s for ATVx80 and ATVxB0), then the device will trip with IDLF.The probable cause is that the main voltage is missing, and the device cannot charge the DC-Bus.
To avoid this error please check mains voltage and ensure its availability.
