Dear Experts
We have special purpose milling machine , with Mitsubishi drive MR J4 500A – one each for X and Y axes
Mitsubishi Electric AC Servo Motor : HG-SR502K, #AC 152V 22A %KW
Error 52.5 on both drives
- X axis was not getting referenced – yesterday we had sudden power failure from Electricity Board and since then, X axis not getting referenced ie sometimes it stops with display showing 5, sometimes 12 etc , earlier we used to have this problem but could be fixed after couple of switch off and on
- As both motors are same, we have marked and swapped encoders between both Motors to isolate problem due to encoder, now due to mismatch, both axes move a little on their ON after Control ON and stops
Request your inputs to resolve this issue
Regards
