6POSITIONING CONTROL

(4)Cautions

(a)For the axis which executes the home position return by the limit switch combined type, if the external input signal has not set in the system settings, a minor error "the positioning control which use the external input signal was executed for the axis which has not set the external input signal in the system settings" (error code: 142) will occur and home position return is not executed.

(b)When the limit switch reverse to home position return direction is turned ON to OFF, deceleration stop is made, home position return is not completed and a major error "external limit switch detection error" (error code : 1101, 1102) will occur.

(c)Home position return retry function cannot be used in the limit switch combined type.

(d)If the home position return is executed with the limit switch OFF, it is started to reverse direction of home position return with creep speed.

(e)When it does not pass (zero pass signal: M2406+20n ON) the zero point from home position return start to deceleration stop by limit switch OFF, a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), if the zero point is not passed until from home position return start to deceleration stop by limit switch OFF, the home position return can be executed.

(f)Deceleration stop is executed after the limit switch OFF. Set the limit switch in expectation of deceleration distance.

(g)If the in-position signal (M2402+20n) is turned ON, home position return is not ended.

(h)When the width is in a zero point, the home position differs from the home position return by the proximity dog type 1, proximity dog type 2, count type 1, count type 3 and dog cradle type.
