4.5.5 Replacing the Belt: RA4R Type
[Items Required for Replacement]
x Replacement belt
RA4R … 60S2M152R Rubber, cleanroom type (Bando Chemical Industries) 6 mm wide
x Allen wrenches
x Tension gauge (capable of tensioning to 7 kgf or greater)
x Strong string, looped (or long tie-band)
x Scale

[Overview of Replacement]
1) Move the rod 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 rod 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, adjust the home offset if you are using an SCON controller. If you are using an SSEL or
X-SEL controller, adjust the home preset.
