Can I automatically acknowledge faults without restarting the inverter or cycling the power?
Yes, this can be done independently of the P1210 setting.To do this you should use the second source of fault acknowledge, P2104. To acknowledge the fault a rising edge must be generated. There are a number of possibilities of how to achieve this, depending on the type of fault is being acknowledged:Example 1 – Most faults occur while the inverter is running, and the fault will cause the inverter to stop. To acknowledge such a fault we require a bit that goes high when the motor has stopped e.g. 56.1 “motor demagnetization finished”. We thus need to set P2104 = 56.1Example 2 – Acknowledging a specific fault which occurs whether or not the inverter is running, such as over voltage. In this case we require a bit which goes high when the over voltage condition has ceased. This is achieved by setting P2104 = 2197.9 (Vcd < P2172) and setting the appropriate voltage level in P2172. Obviously in the case of over voltages being caused by power surges on the mains, measures should be taken to i
