6POSITIONING CONTROL

(4)Cautions

(a)Home position return and continuously start of home position return are also possible in the proximity dog ON in the count type 1.

When the home position return or continuously start of home position return are executed in the proximity dog ON, the home position return is executed after return the axis once to position of the proximity dog OFF.

(b)When the zero point is not passed (zero pass signal: M2406+20n ON) until it travels the distance set in the "travel value after proximity dog ON" from home position return start, a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. When a distance between home position return start position and home position is near and a zero point is not passed, select the count type 3.

(c)When the "travel value after proximity dog ON" is less than the deceleration distance from "home position return speed" to "creep speed", a minor error "an overrun occurred because the setting travel value is less than the deceleration distance at the proximity dog signal input during home position return of count type" (error code: 209) will occur and deceleration stop is made.

(d)If in-position signal (M2402+20n) does not turn ON, home position return is not ended.
