• When the servo power supply is turned on.
• After the automatic deceleration is started during positioning control.
• After the deceleration is started with the JOG start signal OFF.
• During the manual pulse generator operation.
• After the proximity dog ON during a home position return.
• After the deceleration is started with the stop command.
• When the speed change to a speed "0" is executed.
(4) Command in-position signal (M2403+20n) .................Status signal
(a) This signal turns on when the absolute value of difference between the
command position and feed current value becomes below the "command
in-position range" set in the fixed parameters.
This signal turns off in the following cases.
• Positioning control start
• Home position return
• Speed control
• JOG operation
• Manual pulse generator operation
(b) Command in-position check is continually executed during position control.
