Position Switch - ABB IRB 6400R Product On-Line Manual

On-Site Installation

2.6.3 Position switch

There are position switches fitted on axes 1-3. Instructions for fitting and adjusting the
cams and stops follow below.
The cams are mounted in whole lengths and must therefore be cut to suit the applica-
tion. Use a sharp knife and a rubber hammer, for example.
It is important that the entry edge on the cam is chamfered to an angle of max. 30°. If
the angle is larger there is a risk of damaging the position switch (see Figure 16).
The ends of the cam, that are in the channel of the profile, must be cut at an angle of
90° so that the contact area for the stop is as large as possible (see Figure 17).
When fitting the cam, it is important that the edges on the openings at the ends of the
profile are properly chamfered.
The cam stop comprises an M5 nut with an M5 x 6 stop screw. When the screw is
tighten into the material at the bottom of the profile, the nut is pushed up to the top of
the channel and forms a lock for the cam (see Figure 17).
