4.4.3 Single EZ Signal Homing
Most linear motor mechanism set up only one position mark
signal. This mode is used in the said mechanism.
Figure below illustrates how to set up Home mode 2 (single EZ
signal) with positive direction homing. After home movement is
completed the control axis stops at the edge of EZ signal.
