5.1 Disassembly and Reassembly of S-Axis Motor

• Make sure to mount the L-axis fixing jig on the balancer before
performing disassembly and reassembly of the L-axis motor. Also,
be sure to confirm that the L-axis is firmly fixed by releasing the L-
axis motor brake.
Failure to observe this instruction causes unexpected L-arm rotation at
the moment when the L-axis motor is removed, and may result in
damage to machinery, serious injury or death.
• Refer to chapter 4 "L-Axis Fixing Jig" in this manual for the
procedure used to fix the balancer.
Refer to chapter 1 "Notes for Maintenance", chapter 2
"Home Position Return", chapter 4 "L-Axis Fixing Jig".
