3POSITIONING DEDICATED SIGNALS

(2)Rapid stop command (M3201+20n) ..................... Command signal

(a)This command is a signal which stop a starting axis rapidly from an external source and becomes effective when the signal turns off to on. (An axis for which the rapid stop command turns on cannot be started.)

(1) The axis decelerates to a stop in the rapid stop deceleration time set in the

Home position return

parameter block.

 

 

 

(2) A "stop error during home position return" error occurs and the error code [203] is

 

 

 

 

 

stored in the minor error storage register for each axis.

 

 

 

 

 

 

 

 

 

(c)The rapid stop command in a dwell time is invalid. (After a dwell time, the start accept flag (M2001+n) turns OFF, and the positioning complete signal (M2401+20n) turns ON.)

POINT

If it is made to stop rapidly by turning on the rapid stop command (M3201+20n) during a home position return, execute the home position return again.

If the rapid stop command turned on after the proximity dog ON in the proximity dog type, execute the home position return after move to before the proximity dog ON by the JOG operation or positioning.
