Hello I have several wire drawing machines in the plant that i work. Last week a SIEMENS motor start to have a strange comportment. I have think that was the encoder hat have gone, so i changed it. But it still have the same behavior. Then i change the power cable, encoder cable, checked the motor resistance and earth conductivity and all it's OK. So, i think, the problem must be on the SIMOVERT side. Well, i have several equal machines, so i exchange the inverter from one machine to this one but the problem persistes. I became lost and without solutions for this problems. When it have this behavior is when the PLC gives to it on AI1 +0.15V DC, like in the other machines. The corresponding setup is this: Motor: 1PH7-137-2HD02 19.5Kw I will attach the DriveMonitor file also. I hope that someone helps me... Best Regards, Luis Antunes

Hello, do a trace to analyse the reason for this behavior. Speedsetpoint ; Actual speed; ......... See Function diagram 360 on page 589 https://support.industry.siemens.com/cs/ww/en/view/109736629 5.5.3.2 General diagnostics |
With best regards, |
