GA
FUNCTION:
Master Axis for Gearing
DESCRIPTION:
The GA command specifies the master axis for electronic gearing. Only one master may be
specified. The master may be the main encoder input, auxiliary encoder input, or the
commanded position of any axis. The master may also be the commanded vector move
in a coordinated motion of LM or VM type. When the master is a simple axis, it may
move in any direction and the slave follows. When the master is a commanded vector
move, the vector move is considered positive and the slave will move forward if the gear
ratio is positive, and backward if the gear ratio is negative. The slave axes and ratios are
specified with the GR command and gearing is turned off by the command GR0.
ARGUMENTS:
GA n
where
n = X or Y or Z or W or A,B,C,D,E,F,G,H for main encoder as axis master
n = CX or CY or CZ or CW or CA,CB,CC,CD,CE,CF,CG,CH for command position as
master axis
n = S for vector motion as master
n = DX or DY or DZ or DW or DA,DB,DC,DD,DE,DF,DG,DH for auxiliary encoder as
master

Hint: Using the command position as the master axis is useful for gantry applications. Using the
vector motion as master is useful in generating Helical motion.
