• [degree]
0 to 35999999
At start: Bring the current feed value into the software
stroke limit using the manual control
operation.
(Refer to Chapter 11)
Correct the positioning address (Also check
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
to Da.6 and Da.7 in Section 5.3.)

(Refer to Section 9.2.19)
• Do not designate a current value changing using the
positioning data following the continuous path control.
• Do not designate a "current value changing" using the
positioning data following the continuous path control.

<Operation pattern> 00, 01, 11
• 01: Continuous positioning control
• 11: Continuous path control
• Do not designate a speed control, fixed-feed, speed-
position switching control, and position-speed
switching control using the positioning data following
the continuous path control data.
• Do not carry out the fixed-feed, speed control, speed-
position switching control, and position-speed
switching control using the continuous path control
operation pattern.
• Do not carry out the speed control and position-speed
switching control using the continuous path control
operation pattern.
