Any idea how to do this on a Sigma I, with no front display, only with sigmawin+, SGDB servo pack? Thx

Hello MrTon I have a problema with a Yaskawa engine , the servo drive have the signal A.81 I replace two time the encoder and I have the same signal A.81. If posible do you help me ?

Luis
I am guessing the fault comes back on power up.
If the battery backup for the encoder has not been replaced once you power cycle the amplifier the A.81 will reappear.
Also with the A.81 fault there are 3 components you will need to look at. That is the encoder, the encoder cable and the drive. Assuming you have replaced the battery, and 2 motors I would look at the encoder cable for and damage maybe swap out cables. If after all that change the drive.

Hi Mr. do you have any video how get rid of Pot - not fault to turn the drive in run mode?

Good Morning Marco,sorry for the late reply but I worked all weehend, but the answer is yes give me a few days I have to remove the back ground music. You know that whole copy write stuff. But to give a brief run down you go to parameter #PN50A and enter the value n.8881With the number 8881 displayed, press and hold the DATA button until the display flashes. This saves the value to memory. Now to go back to the parameter menu press and hold the DATA button again, now the display should be back at Pn50A. Then scroll to parameter #Pn50b and do the same but enter the value of 8888 than press and hold the DATA button until the display flashes to save the change. And last cycle power.
Hope this helps
Tom

I got running the servo pack
It was not that hard but thinking for awhile. Is so smooth and powerful..
I'm retrofitting a torq-cut 22 1996
But thank you for your help and interest with those issues...
