PCPU READY complete flag (SM500)

The PCPU READY complete flag (SM500) won't turn ON.
How can I turn ON the flag?
Category : 

Answer

The PCPU READY complete flag (SM500) turns ON when no error is detected in the fixed parameters, servo parameters, and limit switch output data, which are checked when the PLC ready flag (M2000) turns OFF to ON.
To turn ON the PLC ready flag (M2000), select [System Settings] - [Basic Settings] - [System Basic Settings] in the MELSOFT MT Works2, and execute either of the following operation in the "Operation at RUN to STOP".
(1) M2000 turns ON by switching from STOP to RUN. (Default)
    Move the RUN/STOP switch of the Motion CPU to "RUN" side.
(2) M2000 turns ON by switching from STOP to RUN and by setting "1" in the setting register.
    Set "1" in the setting register (D704) of the PLC ready flag or turn ON the PLC ready flag (M3072) with the RUN/STOP switch set to RUN.
