Dog type home position return of mitsubishi servo motor

Dog type home position return of mitsubishi servo motor

A home position return method using a proximity dog. With deceleration started at the front end of the proximity dog, the position where the first Z-phase signal is given past the rear end of the dog or a motion has been made over the home position shift distance starting from the Z-phase signal is defined as a home position

(2) Length of proximity dog
To ensure that the Z-phase signal of the servo motor is generated during detection of the proximity dog (DOG), the proximity dog should have the length which satisfies formulas (4.2) and (4.3):
