5. HOW TO USE THE PROGRAM
5 - 55
5.4.11 Dog type front end reference home position return type
POINT
This home position return method depends on the timing of reading DOG
(Proximity dog) that has detected the front end of a proximity dog. Therefore,
when a home position return is performed at a creep speed of 100 r/min, the
home position has an error of 6400 pulses (for HG series servo motor). The
higher the creep speed, the greater the error of the home position.
The home position is where the machine moves the travel distance after proximity dog and the home
position shift distance from the front end of a proximity dog.
The home position return is available independently of the Z-phase signal. Changing the creep speed may
change the home position.
