I'm controlling a AC10 over modbus RTU and everything is working fine. I have configured F905 to timeout if communication is lost, this is also working and the drive trip to CE.However, the fault reset isn't working over modbus when the drive trip into Communication Timeout (CE). I can reset it localy on the drive and on the digital inputs. I have confirmed that in my program I'm sending 7 to command word wich is representing "fault reset", the modbus communication as stated before is also working fine running forward etc. How do I reset CE fault over modbus?/Tim
What do you have F905 set to?
From my experience you can not reset this trip via a Modbus Command as the trip itself means that the drive has lost Modbus communications. It wont try to reestablish this connection until the trip is reset, via the keypad or a digital input.
Turns out that you have wrong modbus information in the manual, I send command word to AC10 with a 7 that is stated in the manual to be fault reset. But it came to my knowledge from our supplier that it should be a 9.Sending a 9 would indeed reset the drive and also the CE error, please confirm that it is indeed a 9 that is correct to use when resetting fault on AC10 drive/Tim
What firmware do you have on the drive (F105)?
