DMC-1400 Series Command Reference GA ● 95
GA
FUNCTION: Master Axis for Gearing
DESCRIPTION:
The GA command specifies the master axes for electronic gearing. Note: This command is
only valid for the DMC-1425. All other Econo series controllers must use the auxiliary
encoder as the master.
The master axis of the DMC-1425 must be either the X or Y axis. These may be specified as
either the commanded position or the actual position. When the master is a simple axis, it
may move in any direction and the slave follows. The slave axes and ratios are specified
with the GR command and gearing is turned off by the command GR0.
NOTE: To gear to the dual encoder using a 141X controller, simply use the GR command.
ARGUMENTS: GA x,x or GAX=x where
x can be X or Y. The value of x is used to set the specified main encoder axis as the gearing
master. The slave axis is specified by the position of the argument. The first position of
the argument corresponds to the 'X' axis, the second position corresponds to the 'Y' axis,
etc. A comma must be used in place of an argument if the corresponding axes will not be
a slave.
x can be CX or CY. The value of x is used to set the commanded position of the specified
axis as the gearing master.
