3.2.2 QD77GF main functions
The outline of the main functions for positioning control with the Simple Motion module
is described below. (Refer to "Section 2" for details on each function.)

Machine HPR control
Mechanically establishes the positioning start point using
a proximity dog, etc. In the data setting method, no axis
movement occurs since the current position is set as the
home position. (Positioning start No. 9001)
8.2
Fast HPR control
Positions a target to the HP address ([Md.21] Feed
machine value) stored in the Simple Motion module using
machine HPR. (Positioning start No. 9002)

control
Linear control
(1-axis linear control)
(2-axis linear interpolation control)
(3-axis linear interpolation control)
(4-axis linear interpolation control)
Positions a target using a linear path to the address set in
the positioning data or to the position designated with the
movement amount.

9.2.3
9.2.4
9.2.5
Fixed-feed control
(1-axis fixed-feed control)
(2-axis fixed-feed control)
(3-axis fixed-feed control)
(4-axis fixed-feed control)
Positions a target by the movement amount designated
with the amount set in the positioning data.
(With fixed-feed control, the "[Md.20] Feed current value"
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.)
9.2.6
9.2.7
9.2.8
9.2.9
2-axis circular interpolation control
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.
9.2.10
9.2.11
Speed
control
Speed control
(1-axis speed control)
(2-axis speed control)
(3-axis speed control)
(4-axis speed control)
Continuously outputs the command corresponding to the
command speed set in the positioning data.
9.2.12
9.2.13
9.2.14
9.2.15
Speed-position switching control
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.
9.2.16
9.2.17
Position-speed switching control
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.
9.2.18
Other
control
Current value changing
Changes the feed current value ([Md.20]) to the address
set in the positioning data.
The following two methods can be used.
(The feed machine value ([Md.21]) cannot be changed.)
• Current value changing using positioning data
• Current value changing using current value changing
start No. (No. 9003)
9.2.19
NOP instruction
No execution control method. When NOP instruction is
set, this instruction is not executed and the operation of
the next data is started.
9.2.20
JUMP instruction
Unconditionally or conditionally jumps to designated
positioning data No.
9.2.21
LOOP Carries out loop control with repeated LOOP to LEND. 9.2.22
LEND
Returns to the beginning of the loop control with repeated
LOOP to LEND.
