At start: Bring the current feed value into the software
stroke limit using the manual control
operation.
(Refer to Chapter 11)

the arc address in circular interpolation with
sub points designated).
New current value:
Bring the new current value into the software
stroke limit. (Refer to Section 9.2.19)
During operation:
Correct the positioning address.
(For the positioning and arc addresses, refer
