LesPaul Posts: 467 Rating: (59)	hello, Not every fault can be acknowledged by Auto-Reset. Only that errors, which can be set to the behaviour 'Error with Restart' (see chapter 7.1.2 into the SIRIUS 3RW44 system manual,link https://cache.automation.siemens.com/dnl/DQ/DQzMzQ1AAAA_21772518_HB/5352195-02DS05.pdf). In this case, the error message will be reset automatically, as soon as the error has gone. If the On-command is still present at 3RW44, the softstarter will restart the motor. All errors, where the behaviour has been set to 'Error without Restart' need an extra Reset-command, before the motor can be started again (after the error has gone). kind regards
