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.)
Chapter 3 Specifications and Functions
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)
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)
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 "[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.)
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 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)
No execution control method. 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.
