11.10.8 Replacing the Motor of the Motor Reversing Type: RCS2-SS7R, SS8R
[Items Required for Replacement]
� Replacement motor with pulley (See the photograph on the
right) (Confirm that the motor has a countermark.)
� PC or teaching pendant
� Tension gauge (capable of tensioning to 7 kgf or greater)
� Strong string, looped (or long tie-band)
� Allen wrenches
� Phillips screwdrivers
� 5.5-mm spanner wrench or needle-nose pliers
[Overview of Replacement]
1) Remove the belt and replace the motor.
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.
