8 AUXILIARY AND APPLIED FUNCTIONS
[Cautions]
(1) 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.
(2) 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.
(3) Home position return retry function cannot be used in the limit switch combined
type.
(4) 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.
(5) 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 : No servomotor Z-phase
pass after power ON" is selected at the time of MR-J2S-B/MR-J2M-B use in the
"condition selection of home position set" of servo parameter (expansion
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.
(6) Deceleration stop is executed after the limit switch OFF. Set the limit switch in
expectation of deceleration distance.
(7) If the in-position signal (M2402+20n) is turned ON, home position return is not
ended.
(8) 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.
