Positioning control of 1-axis is conducted in the control units designated in the fixed
parameters.
(The control unit designation in the parameter block is ignored.)
(1) The interpolation control units designated in the parameter block are checked
against the control units designated in the fixed parameters.
For interpolation control, the result of the interpolation control units designated
in the parameter block differing from the control units designated in the fixed
parameters are listed in the following table.

Positioning is conducted using position commands calculated from the
address, travel value, positioning speed, and electronic gear.

If control units for 1-axis are degrees, use degrees also for the other
axis.

Start Method
Control started using interpolation control units
designated in the parameter block.
Control started using set control units when
!
control units match for axes under interpolation
control.
Control started using the control units with the
!
highest order of priority (see below) when control
units differ for axes under interpolation control.
Order or priority
PLS > degree > inch > mm
<Example>
If axes are set to 1000 pulses and 10.000 inch,
the 10.000 inch setting is considered to be
10,000 PLS.
