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.

Checking origin position
1. Change the CH4 (speed loop gain) of the X axis
(Y axis) driver from 80 to 200.
2. Turn OFF the power to the machine once and
turn it back ON.
3. Set the origin board to the X−Y table.
=CHECK=
x Attach the reference pin (I4.0) to the
positioning lever.
x Make sure that the guide pin is not bent.
4. Create the following NC data.
N1 G1 M0 T0 V4 X0 Y0 Z0
N200400 0 0
N3 0 1 1 0 140.0 67.5 1
5. Input program offset as follows:
M: X=−160.00 Y=−255.00
LL: X=−250.00 Y=−385.00
6. Return the X−Y table to its origin manually.
