10.4 Reversed-home Specification
In the reversed-home specification, the home is located on the front side. This is indicated by “NM” in the model
number. If you wish to change the home direction after the delivery, consult IAI because the moving direction
parameter must be adjusted, as well as the encoder’s Z-phase on certain models.
10.5 Cable Exit Direction
The cable should exit in one of the following four
10.6 Guide with Ball Retention Mechanism
A spacer (retainer) is inserted between adjacent balls (steel balls) in the guide to reduce noise and achieve
smooth operation. This specification is indicated by “RT” in the model number.
There is no longer metal noise generated by colliding balls and thus noise is reduced. Since balls are aligned by
retainers, annoying noise decreases. Wear caused by friction between balls decreases, oil no longer runs out due
to contact, and lubricating oil collects at the retainers. Accordingly, operation becomes smooth.
