Mounting Axis 3 Motor
1)
Perform key alignment, using the new axis 3 motor and pulley. At this time, no
clearance should exist between the motor shaft and pulley.
2)
Secure the axis 3 motor to the axis 3 motor plate with four (4) hexagon socket
head cap screws (M4 x 12) and washers. Be careful with the mounting phases
of the axis 3 motor and the axis 3 motor plate at this time.
3)
Mount the key and the axis 3 motor pulley, and then secure them with the
holding plate, washers and one (1) hexagon socket head cap screw (M3 x 8).

CAUTION
• Perform key alignment very carefully. If there is a clearance between the motor shaft and
pulley, positioning accuracy will drop and the life of the parts will shorten.
