4.7.4 Replacing the Motor of the Motor Reversing Type
[Items Required for Replacement]
� Replacement belt
60S2M180R Rubber, cleanroom type (Bando Chemical Industries) 6mm wide
� Allen wrenches
� 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) (A4R is 0.6mm, A5R
and A6R is 0.7mm 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 A4R is 0.6mm, A5R and A6R is 0.7mm 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 a parameter.
