3.2.2
Using a Belt
1.
Wipe off all of the anticorrosive coating from the motor shaft.
2.
Couple the Servomotor to the machine with a belt.
When you attach the belt, adjust the belt tension so that the allowable radial load given in the Servo-
motor specifications is not exceeded. For details, refer to the catalog of the belt manufacturer.
Select a coupling belt that is suitable for the allowable radial load of the Servomotor and the Ser-
vomotor output. When the Servomotor accelerates or decelerates, the counterforce from the
acceleration/deceleration torque adds tension to the initial belt tension. Take this additional ten-
sion into consideration when you select the coupling belt.
Adjust the belt tension to adjust the radial load. Measure the belt tension at 45° intervals of
the machine shaft. Turn the shaft and take measurements with a belt tension meter at each
point.
Important
Turn at 45° intervals.
