3 SPECIFICATIONS AND FUNCTIONS
3.3.2 AD75 main functions
The outline of the main functions for positioning control with the AD75 are described
below. (Refer to "SECTION 2" for details on each function.)
Main functions Details
Reference
section
Machine zero point return control
Mechanically establishes the positioning start point.
(Positioning start No.9001)
8.2
Zero point
return c
ontrol
High-speed zero point return control
Positions to the zero point address ( Pr.47 ) stored in the
AD75 with machine zero point return.
(Positioning start No.9002) 8.3
Linear control
(1-axis linear control)
(2-axis linear interpolation
control)
Positions with a linear path to the address set in the positioning
data or the position designated with the movement amount. 9.2.2
9.2.3
Fixed-dimension feed
control
(1-axis fixed-dimension feed
control)
(2-axis fixed-dimension feed
control)
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.
9.2.4
9.2.5
Position
control
2-axis circular interpolation
control
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.
9.2.6
9.2.7
Speed control
Continuously outputs the pulses corresponding to the
command speed set in the positioning data.
9.2.8
Speed/position changeover control
First, carries out speed control, and then carries out position
control (positioning of designated movement amount) by
turning the "speed/position changeover signal" ON.
9.2.9
Current value change
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)
