12.1.8 Home position return method 10
Home position return method 10 is the home position return method that runs to the absolute position.
Set the zero point of absolute position by Pn296 and Pn297. When absolute position return is selected, the motor directly
returns from the current position to the set absolute zero point at high speed of home position return speed, and this home
position return method needs to be used with multi-turn absolute encoder.
Example: The current absolute position of the motor encoder is 5 turns 0 pulses, the set absolute return multi-turn value
is 10, the single turn value is 0, then the motor runs directly at high speed for 5 turns.

Note
● 1. When the numerator of the electronic gear ratio is 0, the
denominator setting is the number of
command pulses corresponding to one revolution of motor operation.
● 2. 0.001 ≤ electronic gear ratio (B/A ) ≤ 64000. If the setting range is exceeded, "Parameter error
(Er.d04 ) alarm" will occur.
