Mechanically establishes the positioning start point with a near-
point dog or stopper. (Positioning start No.9001)
Positions to the zero point address ( Pr.47 ) stored in the
AD75 with machine zero point return.
(Positioning start No.9002)
Positions with a linear path to the address set in the positioning
data or the position designated with the movement amount.
Positions the movement amount designated with the
movement amount set in the positioning data.
(With fixed-dimension feed control, the " Md.29 Current feed
value" is set to "0" when starting. With 2-axis fixed-dimension
feed control, the linear path will be fixed-dimension fed with
interpolation.
Positions with an arc path to the address set in the positioning
data, or the position designated with the movement amount,
auxiliary point or center point.
Continuously outputs the pulses corresponding to the
command speed set in the positioning data.
First, carries out speed control, and then carries out position
control (positioning of designated movement amount) by
turning the "speed/position changeover signal" ON.
Changes the Current feed value ( Md.29 ) to the address set
in the positioning data.
The following two methods can be used.
(The machine feed value cannot be changed.)
•
Current value change using positioning data
•
Current value change using current value change start No.
(No. 9003)
Unconditionally or conditionally jumps to designated positioning
data No.
