4.9.2 Operation procedure for homing
The homing operation is divided two steps:
1. Seek for the reference point (rough origin)
After starts the homing function, seek the reference point according to the first speed of
homing. Can use REF input terminal (external detector input), CCWL or CWL as the
reference point, also may use the Z pulse as the reference point. For seeking the reference
point, can choose clockwise or counterclockwise direction operation.
2. Seek for the origin
