GA (Master Axis for Gearing)
[Setting]
DESCRIPTION:
The GA command specifies the master axes for electronic gearing. Multiple masters for gearing may be
specified. The masters 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
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
command and
gearing is turned off by the command GR0.
ARGUMENTS: GA n,n,n,n, or
GAA=n
where
n can be A,B,C,D or N. The value of x is used to set the specified main encoder axis as the gearing master
and N represents the virtual axis. The slave axis is specified by the position of the argument. The first
position of the argument corresponds to the 'A' axis, the second position corresponds to the 'B' axis, etc. A
comma must be used in place of an argument if the corresponding axes will not be a slave.
n can be CA,CB,CC,CD. The value of x is used to set the commanded position of the specified axis as the
gearing master.
n can be S or T. S and T are used to specify the vector motion of the coordinated system, S or T, as the
gearing master.
n can be DA,DB,DC,DD. The value of n is used to set the specified auxiliary encoder axis as the gearing
master.

EXAMPLES:
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.
