jeremy20 Posts: 10 Rating: (0)	my name is jeremy, I'm from chile. work in the port of Valparaiso, which is why I wanted to ask a question. about a problem we have with SIMOVERT MASTERDRIVES We pass this fails. F017 safety and that because of this. A034 Bit 8 in r552 status word 1 of the control channel: slogan. The result of the difference between the Deviation setpoint / actual value and the reference frequency is - If the torque demand is very high. more real than the configured value, and has Elapsed time for monitoring - If the engine is set too regulation. small. - Increase: P792 (Dsv.cna-real: freq. / speed.) Or P794 (T.desv.cna-real). The encoders are reviewed more than 2 times. we have changed with new ones, we have changed the complete line from this envariador encoder, and nothing. Our crane is operating and we played with the parameters P444, P462, P792, P793, P794 ... and all this happens when you put the handle of 0 to 100 so fast. the crane came a little over a year, and now the problem started. if you have any suggestions I would appreciate. Could be a problem club, either in the gearbox of the engines of the trolley?? from Chile jeremy

Now you think that having this connection in the picture number 2, of one of these engines can have a mechanical problem and the inverter sees the two as a single charge. (photo 1 out of curl. Photo 2 input to the motors from inverter) You think doing an engine ID (P115 - 2), with one engine at a time may obtain some results that could help us, and so compare the performance of the engines.

jeremy20 Posts: 10 Rating: (0)	Vithani I know you have checked Encoder but have a look at following thread and try checking as I said... /tf/WW/en/Posts/44242 Regards, Devesh Our problem still persists. we changed the loads connected to each investor. ie the two motors connected in parallel to the inverter 1, we have put the inverter 2. inverter and the motor inverter 2 to 1 with their respective encoder each. is exactly the same in the inverter 1. ie the problem does not change the inverter 2, if not maintained in the inverter 1. really this complicated failure that accuses the inverter 1 (A034) the crane is operating but have not found the fault. what else I can check?
