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.

2. Replacement of Y-Axis Motor Stator and Rotor
2.3 Attachment of Y-Axis Motor Stators and Rotors
(1) Attach Stator 3.
Positioning Method: Push Direction X against the reference pin and Direction Y
against the rear side.
(2) Attach Stator 2.
Be sure to push Stator 2 until it touches Stator 3.
(3) Attach the front rotor to the fixing block in the area of Stator 1 and move it toward the
front side.
(4) Attach the rear rotor to the fixing block in the area of Stator 1 and move it toward the
front side.
(5) Mount Stator 1.
Be sure to push Stator 1 until it touches Stator 2.
(6) Attach the other parts and units that were detached.

Pushing Distance (Clearance) for
Positioning
The thickness gauge of 0.01 mm
should not pass through the clearance.

2.4 Adjustment and Teaching Operations Required after
Replacement
The offsets must be adjusted generally.
Refer to "6. Adjustment of Offsets" in Chapter 5 for details.

3. Replacement of Servoamplifier
3.1 Detachment of Servoamplifiers
(1) Shut down the power to the machine.
(2) Detach the lamp unit for component recognition lighting and set the servoamplifiers
(Fig. D5) in the condition as shown in Fig. D6.
Fig. D5 Servoamplifiers
There is a power source provided only in Section C and it is required to detach the
DC power unit. No power unit is provided in Sections A, B, and D.
(3) Disconnect the connectors, the power
lines, etc., from the object
servoamplifier with the servoamplifiers
being kept in the condition shown in
Fig. D6.
(4) Remove the setscrews of the object servoamplifier
and detach the main body of the servoamplifier.
The shank of the screwdriver should be 20 cm
or longer for this work.
3.2 Attachment of Servoamplifiers
Follow the reverse order of detachment to attach the servoamplifiers.
