Explanation of Homing Mode
(1) 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”.
