Sorry to hear that First, P290 is accessible in level 3 so you need to set 3 in P003 to change value Now second, well I never seen drive not tripping on F0023 while output phase is Open. But anyhow motor must have taken much higher current before it got burnt and it should have tripped earlier or atleast have gone to current Limit P290 is for Inverter overloading, not Motor - this means, this can help you incase you are having 1:1 ratio of drive and motor power. For higher rating drive and lower rating motor, this may not help Please check parameter P640. Set it to minimum you can because this will restrict current flow Also have a look at following TIP to set tripping level on overcurrent /tf/WW/en/Posts/93436#466259 Regards, Devesh Vithani |

Thank you very much for your feedback.. I checked parameter 640 it was 2 but my motor rated current is 0.75 so I reduced it to 1 Amp. Is this OK?? I wanted to know that in case of one phase disconnected from Motor side why Drive was not tripped in Phase Loss F023??? Do I need to configure Parameter P290 and P291(first two bits are reserved and 3rd bit Is for phase loss detection) . Reference post/tf/WW/en/Posts/93837 But I do not have password.

Thats really strange because it should trip. Is it possible, drive tripped and someone tried to reset repeatedily 3-4 times
You dont need to change anything in P291 - Phase loss detection in this parameter is for input side not for Output side Just keep protection setting to minimum and yourmotor will be protected Regards, Devesh Vithani |
