11.9.7 Replacing the Belt of the Motor Reversing Type (RCS2-SA7R)
[Items Required for Replacement]
� Replacement belt � Allen wrenches � Tension gauge (capable of tensioning to 8 kgf or greater)
� Strong string, looped (or long tie-band) � PC or teaching pendant
[Overview of Replacement]
1) Loosen the tension adjustment bolts and replace the belt.
2) Restore the home position.
Press the slider against the mechanical end on the home side, and move the motor shaft away from the
countermark by the specified distance. With the slider and motor shaft affixed in these positions, adjust the
belt to the specified tension.
3) Perform homing using a PC or teaching pendant and check for deviation from the initial home position.
If there is a deviation when the SCON controller is being used, use home return offset distance to make the
adjustments. If the SSEL or the X-SEL controller is being used, use home preset value to make the
adjustments.
[Procedure]
1) Move the slider from the home position toward the mechanical end and check the rotating direction of the
motor. (This check is necessary, because the rotating direction of the motor is different on actuators whose
home is set on the opposite side.)
� Remove the pulley cover.
(Remove the three thin-head mounting screws using an Allen wrench.)
2) Loosen the four tension adjustment bolts and move the motor bracket to slack the belt.
