3 POSITIONING DEDICATED SIGNALS

The condition which M2000 is turned ON to OFF.

Set "0" to the setting register D704 of the PLC ready flag where the RUN/STOP switch is moved to RUN. (The Motion CPU detects the change of the lowest rank bit 1 0 in D704.)

Move the RUN/STOP switch from RUN to STOP.

(2)Start accept flag (M2001 to M2032) ............................ Status signal

(a)This flag turns on when the servo program is started. The start accept flag corresponding to an axis specified with the servo program turns on.

(b)The ON/OFF processing of the start accept flag is shown below.

1)When the servo program is started using the Motion SFC program or Motion dedicated PLC instruction (S(P).SVST), the start accept flag corresponding to an axis specified with the servo program turns on and it turns off at the positioning completion. This flag also turns off when it is made to stopping on the way.

(When it is made to stop on the way by the speed change to speed "0", this flag remains on.)

2)This flag turns on at the positioning control by turning on the JOG start command (M3202+20n or M3203+20n), and turns off at the positioning stop by turning off the JOG start command.

3)This flag turns on during the manual pulse generator enable (M2051 to M2053: ON), and turns off at the manual pulse generator disable (M2051 to M2053: OFF).

4)This flag turns on during a current value change by the CHGA instruction of servo program or Motion dedicated PLC instruction (S(P).CHGA), and turns off at the completion of the current value change.
