Acknowledgement
In most cases, you have the following options to acknowledge a fault:
● Switch-off the inverter power supply and switch-on again.
● Acknowledgement signal at digital input 2
● Acknowledgement signal in bit 7 of control word 1 (r0054) for Control Units with fieldbus
interface
Faults detected during the inverter-internal monitoring of hardware and firmware can be
acknowledged only by switching the supply voltage off and on again. The list of faults in the
List Manual contains a note on this limited acknowledgement possibility.
