1. Installation of the motor
Open three 9mm holes on the table as seen from
the above. Install the motor securely using the
installation bolts, washers, spring washers and
nuts.
The installation bolts, etc., are included with the
motor as accessories.
3. Installation of the pulley
*
To properly install, the protective cover A (motor side of the protective cover) must be
installed onto the motor before the pulley is installed. (Refer to "5. Installing the protective
cover”.)
Securely tighten the pulley
.
Select the correct pulley diameter to ensure complete use of the motor performance.
Selection of the motor pulley:
Motor pulley
outer diameter (mm)
(*) The motor speed should be set at 3,600rpm. When the motor pulley diameter is selected with the above method
and the pulley diameter is too small, select the minimum pulley in the range that the belt will not slip.
(**) Refer to page 20 for the pulley diameter to be used when using the Mitsubishi thread trimming sewing machine.
4. Mounting of the belt
To adjust the belt tension, press down on the center of
the belt with your hand, and turn the upper and lower nuts
of the adjustment nut to increase or decrease the center
height of the motor so that the belt dips approximately
15mm.

2. Installation of the control box
(1) Tighten the control box onto the motor.
(2) Insert the power cord from the motor into the connector on the
back of the control box. Insert the encoder cord from the motor
into the encoder connector on the front of the control box.
If the belt tension is too low, the medium
and low speeds will be inconsistent, and
the stopping precision will be poor.
When too tight, the motor bearings will
deteriorate.
Caution
For safety always turn the power
switch off, before adjusting the belt.
Caution
Use the JIS K6323 sewing
machine belt M-type.
