Adjusting guide rail position
1. Set a PC board and tighten the hexagon headed
bolts (x 4) enough to hold the board in place.
2. While checking with a gap gauge, move the
guide rail until the distance between the side of
the PC board and the side of the guide rail is
0.3 mm in all places.
3. After making adjustments, retighten the hexagon
headed bolts (x 2) and bolts A (x 2) so as to fix
the guide rail in place. Slide the PC board along
the rails checking to make sure it slides without
catching or incurring other irregularity.

Motor removal and mounting (X−axis)
1. Change the CH4 (speed loop gain) of the X
axis (Y axis) driver from 200 to 80 before
turning OFF the power to the machine. (Refer
to ‘7.3 Digital Operator’ for details on how to
change the value.)
2. Turn OFF the power and disconnect the motor
connectors.
3. Remove the ball screw cover of the X axis (Y
axis).
4. Loosen the N coupling nut on the motor side.
5. Remove bolts B (x 4) and the motor.
=REFERENCE=
x When removing bolts B, support the
motor by hand so that it doesn’t drop out
of position.
x Strip away all old sealant tape from the
threaded part of the N coupling and
rewrap with new tape.
6. Mount the new motor and fix with bolts B (x 4).
=CHECK=
Ensure that the motor axis inserts smoothly
into the N coupling.
