MSO instruction stuck at EN bit

[bdauliya]

Gentlemen,

I have come across an issue which I can't understand. So I had to change the 35:1 gearbox with 25:1 gearbox. I did change the transmission ratio on scaling from axis properties. After that my servos wouldn't enable, the MSO EN bit is set but DN bit never sets also there is no ER bit set.

The Rung condition hasn't been changed from original logix program, only thing that changed was transmission ratio. The Drive is 2198-C4015-ERS and the controller is 5069-L306ERM Compactlogix.

If you have changed the mechanical part of the servo loop. You need to go back and redo the tuning procedures. I think once it knows the new parameters I think the MSO EN bit set but DN bit never sets will go way.
