7.1.2 Mode 4
Reference search mode 4 searches the left end switch only, but from both sides so that the middle of the
switch will be found and used as the zero point. This is shown in figure 4.
Add 64 to the mode number (i.e. set axis parameter #193 to 68) to search the right end switch instead.

7.1.3 Mode 7
Reference search mode 7 searches the home switch in positive direction, ignoring the limit switch inputs.
It is recommende mainly for use with a circular axis. The exact middle of the switch will be found and used
as the zero point. Figure 5 illustrates this.
Add 128 to the mode number (i.e. set axis parameter #193 to 131) to reverse the polarity of the home
switch input.
