11.9.6 Replacing the Belt of the Motor Reversing Type (RCS2-SA4R, SA5R, SA6R)
[Items Required for Replacement]
� Replacement belt � Allen wrenches � Phillips screwdriver
� Tension gauge (capable of tensioning to 7 kgf or greater)
� Strong string, looped (or long tie-band)
� Scale � Oil-based marker pen
� PC or teaching pendant
[Overview of Replacement]
1) Move the slider to a position where Z-phase turns on (home position) (2 mm from the mechanical end). In this
position, loosen the motor-unit affixing bolts and replace the belt.
2) Restore the home position.
Affix the slider at a position 2 mm from the mechanical end on the home side, pass the belt, and 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.
