R232, For selecting the axis in JOG and HOME mode to be drivable
When in JOG or HOME mode, use R232 to select the axis to be drivable as
follows.
BIT 1 0
Chose Axis Y X
When R232 = 1 → Bit 1=0 & Bit 0=1, X-axis is drivable.
When R232 = 2 → Bit 1=1 & Bit 0=0, Y-axis is drivable.
When R232 = 3 → Bit 1=1 & Bit 0=1, both X and Y-axis are drivable.
