The outline of the main functions for positioning control with the QD75MH is described
below. (Refer to "Section 2" for details on each function.)
Mechanically establishes the positioning start point using
a near-point dog or stopper. (Positioning start No. 9001)
Positions a target to the OP address (
feed value) stored in the QD75MH using machine OPR.
(Positioning start No. 9002)
Positions a target using a linear path to the address set in
the positioning data or to the position designated with the
movement amount.
Positions a target by the movement amount designated
with the amount set in the positioning data.
(With fixed-feed control, the"
is set to "0" when the control is started. With
2-, 3-, or 4-axis fixed-feed control, the fixed-feed is fed
along a linear path obtained by interpolation.)
Positions a target using an arc path to the address set in
the positioning data, or to the position designated with the
movement amount, sub point or center point.
Continuously outputs the command corresponding to the
command speed set in the positioning data.
First, carries out speed control, and then carries out
position control (positioning with designated address or
movement amount) by turning the "speed-position
switching signal" ON.
First, carries out position control, and then carries out
speed control (continuous output of the command
corresponding to the designated command speed) by
turning the "position-speed switching signal" ON.
Changes the Current feed value (
set in the positioning data.
The following two methods can be used.
(The machine feed value cannot be changed.)
• Current value changing using positioning data
• Current value changing using current value changing
start No. (No. 9003)
No execution control system. When NOP instruction is
set, this instruction is not executed and the operation of
the next data is started.
Unconditionally or conditionally jumps to designated
positioning data No.
Carries out loop control with repeated LOOP to LEND.
Returns to the beginning of the loop control with repeated
LOOP to LEND.
