(4) About data setting type count type 2) (QD75M) Common to all full closed encoders
In the data setting type/count type 2) (QD75M) home position return method, a home position return
can be normally made if the home position has been passed through (in either direction) before start of
a home position return, since a scale home position (reference mark) or the Z-phase signal of a rotary
encoder is not required.
When the linear scale used does not have a scale home position (reference mark) or the machine has
no distance of one motor encoder revolution until the Z phase of the rotary encoder is passed through,
a home position return can be made by changing the parameter (Pr. 33 "home position setting
condition selection") setting if the home position is not yet passed through.
