[Operations]
(1) Calls/starts the Motion SFC program of the specified program name.
(2) Control varies with the type of the transition coupled next to the subroutine
call/start step.
(a) WAIT (Subroutine Call)
When the subroutine call step is executed, control transits to the specified
program as shown below, and when END of the called program is executed,
control returns to the call source program.
program as shown below, and when END of the called program is executed,
control returns to the call source program.
(b) Except WAIT (Subroutine Start)
When the subroutine start step is executed, control starts the specified
program and then shifts to the next as shown below. Since, the start source
and destination Motion SFC programs are executed in parallel. The started
program ends at END execution.

[Errors]
(1) When the specified Motion SFC program does not exist at a subroutine call/start,
