7.4.4.2 Closed loop stepping motor (40274-E018) for R. V. PM
Replacement part: 40274-E018
1 . Remove the R V-axis ASSY (40274-2300)
.
2 . Loosen the two supplied screws of the
coupling (40274-M248) through the two
holes on the R V-screw holder (40274-
M241).
3 . Widen the space between the R bracket
(40271-M256) and R V-screw holder
(40274-M241) as much as possible.
4 . Unscrew SB3 × 35 (n = 4) to replace the
closed loop stepping motor (40274-E018)
for R. V. PM.
5 . Reassemble the parts in the reverse order.
6 . Perform the following.
4 ) Backing up the EEPROM data
Rotate the ball screw (40273-
M245) to align the supplied
screws of the coupling
(40274-M248) and the holes
of the R V-screw holder
(40273-M241).
Caution
Widen the space just enough so that the tip of the ball screw (40273-M245)
does not go inside the R bracket (40271-M256).
If the space is widened too much, the ball inside the nut drops out and the ball
screw becomes unusable.
