Disassembly and Reassembly of the L-Axis Motor
• Refer to
Fig. 5-2 “Disassembly & Assembly of L-Axis Motor”
Disassembly
1. Turn OFF the DX100/DX200/FS100 power supply.
2. Unscrew the hexagon socket button head screws
and remove the
covers on the right and left sides
3. Connect the backup battery with the cable of L-axis motor
.
(Refer to
Chapter 2 “Notes for Maintenance”
4. Disconnect the cables (both encoder and power-cables) of the L-axis
motor
from the internal wiring harness.
5. Unscrew the GT-SA bolts
and remove the L-axis motor
with the
M-base
. When remove the motor, support the U-arm to avoid it from
rotating.
6. Unscrew the GT-SA bolts
and remove the M-base
from the L-axis
motor
.
7. Unscrew the hexagon socket head cap screw
and remove the
pulley
.
Reassembly
1. Mount the pulley
on the L-axis motor
.
2. Attach the conical spring washer to the hexagon socket head cap
screw
, then apply LOCTITE 242 to the thread part and tighten it with
the tightening torque shown in
.
3. Mount the M-base
on the L-axis motor
and tighten the GT-SA
bolts
with the tightening torque shown in
.
4. Mount the L-axis motor
which is reassembled to the step 3 on the
U-arm and put the timing belt on the pulley
.
5. Attach the conical spring washers to the GT-SA bolts
, tighten them
with the tightening torque shown in
“Disassembly and Reassembly of L- and U-Axis Timing Belts”
and
adjust the initial tension of the timing belt.)
6. Connect the cables (both encoder and power-cables) of the L-axis
motor
with the internal wiring harness.
7. Remove the backup battery.
8. Mount the cover
and tighten the hexagon socket button head
screws
with the tightening torque shown in
.
9. Turn ON the DX100/DX200/FS100 power supply.
