VS40 TOOL CAROUSEL HOME POSITION

This mill has Fanuc 18M control. The battery was replaced on the tool carousel servo drive unit. We need a procedure to move the carousel in small increments to establish correct tool alignment and then toggle the 1815 parameter.
Does anyone have this procedure?

Did you get this fixed?

It's a Seicos 18M and a Fanuc 18iMa

K000.7 is magazine handle select.

Making this keep relay allows the MPG to operate the tool chain when placed in the 4th axis.
