[ d ] System Work Number
The system work number n (setting range: 1 to 16) used when executing motion programs is set by the MSEE work
registers.
This system work number is enabled only when the motion program control signal bit D (system work number setting)
is ON. The status bit, bit E (No system work error), will turn ON if the work number setting is outside the setting range
or the specified system work is in use.
The total number of system works of a motion program is 16 for both M-EXECUTOR and ladder. The number
configured in the number of program definitions of the M-EXECUTOR detailed screen is set for the system
work for M-EXECUTOR.
1. A work not occupied by M-EXECUTOR can execute a motion program using a MSEE command from a ladder program.
2. When the number of a system work occupied by M-EXECUTOR is specified by a ladder program, an alarm (Error without a
system work) occurs. Therefore, when the number of program definitions is set to 16 in the M-EXECUTOR detailed screen,
a motion program cannot be executed by a ladder MSEE command.
• Error without a system work: Status flag Bit E of the motion program
