6) Tension the belt.
� Here, two ways to tension the belts are explained: one using a sound-wave tension gauge (= tension
method) and the other using a tension gauge (= pull method).
If the actuator is of the high-precision specification or used with the high acceleration/deceleration
option, use of the tension method is recommended because the tension can be adjusted more
accurately.
6)-1 Tension method
[1] Remove the screw on the side face of the bracket on the motor reversing side.
Applicable screwdriver : Phillips (+)
Applicable screw : Crosshair socket pan-head machine screw M4 x 4 (SUS)
[2] Have a hexagonal socket head bolt M3 x 15 ready as the tension bolt.
If no hexagonal socket head bolt M3 x 15 is available, remove one bolt of this size from the removed motor
unit and use it as the tension bolt. (See the figure below.)
