5.5.1 Types of reference point definitions
The SIXpack 2 provides two completely different types to define the reference point:
5.5.2 Hardware installation
5.5.2.1 Connection of electrical reference switch
The reference switch is connected to the pins „Ref_In“ and „GND“. Optionally a series resistance of
about 2.2kOhms can be inserted to match EMC demands. In general using an opener, i.e. a normally
closed switch is advisable. So broken cables can be detected. The reference input is equipped with a
Schmitt-trigger.
5.5.2.2 Wiring with stop-switches
To prevent driving beyond the ends of a linear axis stop-switches can be used. They are connected to
pin „A_In“ of the motor connector. Again, openers should be used as stop-switches for the reason
mentioned above.

At start point or end point a stopper for the mechanic of the axis is build in. At reference search
the SIXpack 2 moves the respective axis in direction of the stopper (defined by the flag
MT_NULLLEFT, SQPack-tab: “Reference search”, CMD $15) for a distance of Poslimit * 5/4.
The multiplication with 5/4 causes the SIXpack 2 to reach the stopper before end of the reference
search. The motor is mechanically stopped, reference point is reached.
At any point of the positioning scale of the axis an electrical switch is implemented which is
activated by the passing motor. The SIXpack 2 catches this for reference point.
A reference switch attached one end of a linear axis can be used as end switch. At activation of
the switch the motor stops.
