代码 231-88F0: Inverter and supply module readiness is missing %s

[Cause of error] - While the drive was still under servo control, both the Ready signal of the inverter and the Ready signal of the supply module were switched to inactive. - Possible causes: - UV was switched off over X70 - Fault clearance of the UV: - Dropout in power supply - DC-link voltage is too high - DC-link voltage is too low - DC-link current is too high - PLC or external wiring switched UV off - Noise signals on wiring CC -> UV, CC -> UM - CC controller unit is defective. [Error correction] - Check the diagnostic LEDs on the UV in the event of an error - Check the power supply of the UV - Check the enabling signal on X70 - Check whether the braking resistor is connected for a non-regenerative power supply. - Check the cable ground and shield - Exchange the supply module and the power module - Exchange the CC controller unit. - Inform your service agency.
