1. Replacement of X-Axis Motor Stator and Rotor
1.1 Detachment of X-Axis Motor Stator
(1) Shut down the power to the machine.
(2) Move the head unit (rotor) to the
rear side of the machine.
(3) Detach the X-axis linear scale
together with the block.
(4) Detach the protective cover.
(5) Attach the stator carrier jig to
Stator 1.
(6) Remove the setscrews of Stator 1.
(7) Detach Stator 1 in the pullout
direction shown in Fig. D1.
(8) Move the rotor outside of the
machine.
(9) Attach the stator carrier jig and
detach Stator 2
1.2 Detachment of X-Axis Motor Rotor
(1) Detach Stator 1.
(2) Detach the head unit.
Refer to "1. Replacement of Head Unit" in Chapter 5 for details.
(3) Open the head wiring section and pull out the power connector of the rotor.
Refer to "1. Replacement of Head Unit" in Chapter 5 for details.
(4) Move the head mounting block to the area of Stator 1.
(5) Loosen the setscrews and detach the rotor from the mounting block.

1. Replacement of X-Axis Motor Stator and Rotor
1.3 Attachment of X-Axis Motor Stator and Rotor
(1) Push Stator 2 against the stator positioning pin and tighten the setscrews to fasten the
stator securely.
(2) Detach the stator carrier jig.
(3) Attach the rotor to the mounting block in the area of Stator 1.
Positioning of Rotor
(3.1) Position the rotor such that the power line of the motor can be located on
the top of the rotor. (cf. Fig. D2)
(3.2) Attach the rotor to the head mounting block by temporarily tightening the
setscrews.
(3.3) Push the rotor against the positioning pin of the mounting block and
tighten the setscrews securely.
(4) Move the rotor toward Stator 2.
(5) Attach Stator 1 from the opposite side
of the pullout direction shown in
Fig. D2.
(6) Push Stator 1 against Stator 2 and
fasten it by tightening the setscrews
securely.
(7) Attach the stator carrier jig of Stator 1.
(8) Check the clearance between the stator
and the rotor.
Specified Value: 0.7±0.2 mm
(9) Connect the power connector of the
rotor to the wiring section.
Refer to "1. Replacement of Head
Unit" in Chapter 5 for details.
(10) Attach the protective cover and the
X-axis linear scale block.
(11) Check the position of the linear scale and the light intensity of the X-axis encoder.
Refer to "6. Replace of Linear Scale" for details.
(12) Attach the head unit.
Refer to "1. Replacement of Head Unit" in Chapter 5 for details.
It is recommended that new setscrews should be used for the stators.
1.4 Adjustment and Teaching Operations Required after Work
The offsets must be adjusted generally.
Refer to "6. Adjustment of Offsets" in Chapter 5 for details.

2. Replacement of Y-Axis Motor Stator and Rotor
2.1 Detachment of Y-Axis Motor Stators
• Detach Stator 1, Stator 2, and Stator
3 in this order as shown in Fig. D3.
Keep this order because the
positional reference pins of the
stators are located on the front side
of the device.
(1) Move the rotor toward Stator 2
beforehand.
(2) Attach the stator carrier jig to Stator 1.
(3) Remove the setscrews.
(4) Detach Stator 1 by slowly pulling it
out in the pullout direction shown in
Fig. D3.
(5) Follow the same procedure to detach
Stators 2 and 3.
Before the stators for the Y1 axis are detached, it is required to detach the rear
operation monitor, the ceiling pillar, the mechanical stopper, and the robot cable, etc.
2.2 Detachment of Y-Axis Motor Rotors
• Be sure to detach the rear rotor first
and then the front rotor.
(1) Detach the beam first.
(Including the robot cable, etc.)
(2) Move the rotor toward Stator 2.
(3) Detach Stator 1.
(4) Move the rotor to the area of Stator 1.
(5) Loosen the setscrews of the rotor and
detach the rotor.
