3 POSITIONING DEDICATED SIGNALS
(8) All axes servo ON command (M2042) ................. Command signal
This command is used to enable servo operation.
(a) Servo operation enabled ...... M2042 turns on while the servo OFF command
(b) Servo operation disable ....... • M2042 is off
Execute this command after positioning completion because it becomes invalid
during positioning.
All axes servo ON command
(M2042)
All axes servo ON accept flag
(M2049)
(Note)
Each axis servo ready state
POINT
When M2042 turns ON, it is not turned off even if the Motion CPU is set in the
STOP state.
M2042 turns OFF by the forced stop of Motion CPU.
(9) Motion slot fault detection flag (M2047) ...................... Status signal
This flag is used as judgement of which modules installed in the slot of Motion
management are "normal" or "abnormal".
• ON .......... Installed module is abnormal
• OFF .......... Installed module is normal
The module information at the power supply on and after the power supply ON
are always checked, and errors are detected.
(a) When M2047 turns OFF in operation, the operating axis decelerates to a
stop.
(b) When an error occurs, the 7-segment LED at the front side of Motion CPU
shows the system setting error.
The error contents can be confirmed using the monitor of MT Developer2.
(c) When M2047 is ON, positioning cannot be started. Remove an error factor,
and turn the Multiple CPU system's power supply on again or reset.
(10) JOG operation simultaneous start command (M2048)
(a) When M2048 turns on, JOG operation simultaneous start based on the
JOG operation execution axis set in the JOG operation simultaneous start
axis setting register (D710 to D713).
(b) When M2048 turns OFF, the operating axis decelerates to a stop.
(M3215+20n) is off and there is no servo error.
• The servo OFF command (M3215+20n) is on
• Servo error state
• Forced stop
