Fig. 6−36 Homing in mode 4
0 Negative hardware limit switch
1 Zero pulse (zero position of the position encoder)
2 Reference switch
3 Positive hardware limit switch
4 Load (e. g. slide)
5 Direction of travel
6 Home position
The load (e.g. slide) travels from its original position to the reference switch. At the
approached reference switch the direction of travel is reversed and the load travels to the
first zero pulse after leaving the reference switch. The zero pulse bears the home position.
If the drive is already situated at the reference switch, the direction of travel is reversed
immediately.

Note!
ƒ Single−turn absolute value encoder (SinCos encoder) and resolver do not
have a zero pulse. Here the zero position corresponds to the zero pulse.
ƒ For multi−turn absolute value encoders only homing modes 8 ... 15 can be
used (C3010 = 8 ... 15).
Modes 6 and 7
Modes 6 and 7 (C3010 = 6 or 7) are functionally not assigned or reserved for possible
future mode supplements.
