4 . POSITION ADJUSTMENT OF THE MOTOR CORD EXIT HOUSING (BLUE
AREA) ON THE EM- 4020 A and EM- 4040 A
The Motor Cord Exit Housing (Blue Area) of the EM-4020A and EM-4040A can be adjusted by rotating to a desired
position.
CAUTION
Motor Cord Exit Housing (Blue Area) cannot
be rotated more than 360 degrees. If forcibly
rotated, the mechanical stop inside the Exit
Housing will break and cause the base of the
cord to kink, leading to internal damage of the
cord.
① Loosen the Fastening Screw (3 locations) of the Motor
Cord Exit Housing.
② Adjust the Motor Cord Exit Housing to the desired
position.
③ Re-tighten the Fastening Screws (3 locations) of the
Motor Cord Exit Housing.
5 . CONNECTION OF MOTOR CORD
CAUTION
・
Before connecting to the Motor Cord to the Motor and CONTROLLER, verify the Main Power
Switch in the CONTROLLER is turned OFF. If the Main Power Switch on the CONTROLLER is
ON while connecting the Motor Cord, damage to the CONTROLLER is possible.
・
Install the protective cover (Protective Cover etc.) to prevent damage or contamination to the
Motor Cord Plug when not in use.
① Remove the Protective Cover of the Motor Cord (Motor Power Line and Motor Signal Line).

6 . CCONNECTION TO THE SPINDLE
CAUTION
Make sure your hands and all interlocking parts of the spindle and motor are clean before
connecting the motor to the spindle. This is critical in preventing contaminants from entering
the motor or spindle.
Align the threads on the front end of the motor and the rear end of the spindle, then rotate the spindle clockwise. If
the drive shaft of the motor does not engage the drive dog on the spindle, it will not be possible for the spindle to
rotate. DO NOT FORCE THIS CONNECTION. Turn the spindle back a few threads, rotate the collet cap or spindle
shaft slightly by hand until the drive shaft and the drive dog are fully engages. This may take several attempts.
Use the 36mm wrench that have been provided for the final tightening of the spindle to the motor.
