We are looking for Electrical prints and manuals for a KIA KT20 w/ a Fanuc O-M control. Need to diagnose some problems but have no books.
The spindle will run in high and low but when you give it a command to go 1250 rpm in MDI it goes 2500rpm .Also in low it wont run the speed you command. Always faster.
The shifter is set up for M40 and M41 and were used to M41 and M42 to shift from low to high. Could there be a parameter issue??
Diagnostic number 712 changes bit 7 to a 1 when this problem occurs with the rpm issue
Also the tailstock needs to be extended and we don't know how to turn this setting off to run spindle.

Any help would be great

Hi,

You can check parameter:
- 0577 Spindle speed command offset (always set to 0)
- 0516 Spindle speed command gain adjustment (always set to 1000)
Which spindle motor do you have?
