3 POSITIONING DEDICATED SIGNALS

(b)An in-position check is performed in the following cases.

•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. This check is not executed during speed control or speed control in the speed/position switching control.
