Control units for interpolation control

Interpolation Control Units in Parameter Block

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.

(1) Circular interpolation control
If control units for one axis are degrees, use degrees also for the other
axis.

If axis is set to 1000 PLS and 10.000 inch, the
10.000 inch setting is considered to be 10,000
