Explanation of Homing Mode
A: Home Sensor Type and Homing Direction
Left or right limit switch can be used as a reference “Home” for homing function. It also can use extra sensor,
such as proximity switch or photo switch as reference “Home”. When the servo motor runs within one
revolution only, users also can set Z-phase pulse as a reference “Home”.
A=0: Forward homing and CCWL limit input point is regarded as a rough reference “Home”. When home is in
position, CCWL will turn into limit input function. If trigger CCWL afterward, the limit alarm will occur.
When use limit input point as a rough reference “Home”, we recommend users to set B=0, i.e. return to
find Z-phase pulse during homing and regard Z-phase pulse as a precise mechanical “Home”.
A=1: Reverse homing and CWL limit input point is regarded as a rough reference “Home”. When home is in
position, CWL will turn into limit input function. If trigger CWL afterward, the limit alarm will occur. When
use limit input point as a rough reference “Home”, we recommend users to set B=0, i.e. return to find Z-
phase pulse during homing and regard Z-phase pulse as a precise mechanical “Home”.
