Error factor
Description
• The code exists but is grammatically
erroneous.
• Though not within branch-coupling, a
label/jump code within selective branch-
coupling or a label/jump code within
parallel branch-coupling exists.
Selective branch destinations are all headed
by other than SFT or WAIT transitions.
WAITON/WAITOFF is not followed by a
motion control step. (However, this is
permitted to a pointer (Pn) or jump (Pn).)
A parallel branch is followed by an END
step without a parallel coupling.
An impossible code is used.
The internal code is corrupted.
Internal code (list code) error in jump
destination information
Internal code (label information) error in
jump destination information
Internal code (label No.) error in jump
destination information
Internal code (label address) error in jump
destination information
The specified pointer does not exist at the
jump destination.
The self program was called/started by
GSUB.
The main program was called/started by
GSUB.
Nesting of parallel branches within a parallel
branch route exceeded four levels.
An attempt was made to execute a motion
control step K with an event or NMI task.
The number of simultaneously active steps
exceeded 256 during execution.
Error Processing
Stop to execute the
applicable Motion
SFC program No.
For the subroutine
called program, the
call source program
also stops to
execute.
12 - 8
Corrective Action
The Motion SFC program code is corrupted.
Turn PLC ready flag (M2000) OFF and write
the Motion SFC program again.
Or, replace the external battery if it passed
over a life.
GSUB cannot call its own or main program.
Correct the Motion SFC program.
The nesting of parallel branch is up to four
levels.
Subroutine the branch destination
processing and correct the program.
Motion control steps cannot be executed in
the Motion SFC programs executed by the
event and NMI tasks.
Number of simultaneously active steps is
maximum 256. Re-examine the Motion SFC
program.
