hello guys,

I have a CNC Milling machine with 3 axes. FANUC 0i MODEL D
the axes use a pulse coder + linear scale to know it's position
I want to remove the linear scale from the Y axis. (i don't care of the accuracy)

I tried to remove it but these alarms appeared:
DS0300 (Y)APC ALARM: NEED REF RETURN
DS0307 (Y)APC ALARM: BATTERY LOW 1

When i connect the linear scale again the alarms disappear.
So how can i correctly remove the linear scale from this axis?
