[Cautions]
(1) 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.
(2) 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.
(3) 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.
(4) If in-position signal (M2402+20n) does not turn ON, home position return is not
ended.
