■Description, data type of result
*1 For operating system software version "09" or earlier, 78 to 5444.
Processing details
• Machine program operation start request is performed for the machine positioning data from the starting No. specified with
(S1), for an area size specified with (S2).
• Refer to the following for machine positioning data stored in the device specified with (S1).
MELSEC iQ-R Motion Controller Programming Manual (Machine Control)
• The machine positioning data that may be set at (S2) is within the range 78 to 10820 (for operating system software version
"09" or earlier, 78 to 5444).
Operation error
An operation error will occur and a machine program operation start request will not be made if:
• (S1) is not an even-numbered device. (Details code: 1)
• The device No. of (S1)+(S2) is outside the range. (Details code: 2)
• Instruction area for MCNST instruction is not enough. (9 or more instructions operate in the Motion dedicated PLC
instruction (M(P).MCNST/D(P).MCNST) and Motion dedicated function (MCNST))(Details code: 3)
• Machine positioning data area settings are wrong. (Details code: 4)
• The points set to the data area in (S2) are not inside the range of 78 to 10820 (for operating system software version "09"
or earlier, 78 to 5444). (Details code: 4)
• There is an excess/deficiency in the data area points for the area calculated from the number of points for every point.
(Details code: 4)
• The number of positioning points is outside the range of 1 to 256 (for operating system software version "09" or earlier, 1 to
128). (Details code: 4)
• The control method specified by machine positioning data is wrong. (includes when the control method for every point is
NOP only) (Details code: 5)
• The machine No. specified by machine positioning data is outside of range. (Details code: 6)
