■Setting of the starting axis
The starting axis set as (S1) is set J + Axis No. in a character string " ".

Up to 12 axes can be set. Set them as shown below. Set "J" in a capital letter or small letter and use the axis No. set in the
servo network setting as the axis No. to start. Refer to the following for servo network settings.

Also, the axis No. to start does not need to be in order.
Ex.
When multiple axes (Axis1, Axis2, Axis10, Axis11) are set.
• "J1J2J10J11"
• "j1j2j10j11"
• "J1 J2 J10 J11"
If the start axis specified by (S1), and the axis No. specified in the servo program to be started are verified and match, the
servo program starts. If the specified axes do not match, a minor error (error code: 19FBH) occurs, and the servo program
does not start.
When an empty character string " " is specified to (S1), the axis specified in the servo program starts without verifying axis No.
When indirectly specifying an axis No. in the servo program, specify " " to (S1).
[When " " is specified to (S1)]
When omitting the axis No., the timing of the start accept flag and start accept flag for the command
generation axis turning ON is slower than when the axis No. is set. (Page 82 Start accept flag (System
area))
• When axis No. is set: When instruction is received
• When axis No. is omitted: When instruction is analysed
[When an axis No. is specified to (S1)]
When starting the START instruction with M(P).SVST/D(P).SVST, regardless of whether all start axes are set,
if one or more axis No. of the start axes is specified in each servo program instruction in the START
instruction, the servo program starts without error.
