Using The Z-
Channel
Figures K through O show the homing operation when homing to an encoder index pulse, or Z
channel, is enabled (HOMZ1). The Z-channel will only be recognized after the home input is
activated. It is desirable to position the Z channel within the home active region; this reduces
the time required to search for the Z channel.
