6.2.2 Data Variables (M Registers)
(1) Overview
M registers are general-purpose variables that can be used in ladder logic programs, user functions, motion pro-
grams, and sequence programs. These are global variables that can be used as interfaces between motion pro-
grams, sequence programs, and ladder logic programs.
(2) Description
M registers are designated as follows:
The M register can be used as a variable for each type of operation and substituted for the operation result, or
specified as the variable for the positioning coordinate value or the speed. The variable number is expressed as a
decimal.
(3) Programming Examples
(a) Specifying the Position and Speed in Axis Move Commands as Variables
(b) Using Variables in Operations
• Bit Designation
• Integer Designation
• Double Integer Designation
• Real Number Designation
When the travel distance coordinate values or speed is designated as a variable in the following motion com-
mands, double integer data must be used.
MOV, MVS, MCW/MCC, ZRN, SKP, MVT, EXM, POS, ACC, SCC, IAC, IDC, IFP, FMX, INP, VEL
