11.5 Hall sensor

The magnetic pole sensor, also known as the Hall sensor, can be used to detect the motor pole.

The servo drive must know the position of the motor magnetic field to efficiently actuate the

motor and move the motor in the right direction. As shown in the following figure, the Hall sensor

generally sends three-phase signals. The Hall sensor divides the motor magnetic field from 0° to

360° by the three-phase signals into six blocks (1, 0, 1), (1, 0, 0), (1, 1, 0), (0, 1, 0), (0,1,1), and

(0,0,1), so that the servo drive can know the current position of the motor magnetic field. Before

using the linear motor, check if it is equipped with a Hall sensor (or determine whether to use

the Hall sensor according to the Motor Parameter Identification Wizard). If a Hall sensor is

installed, set PM.003.Y to 1. If you are not using the installed Hall sensor or the linear motor is

not equipped with a Hall sensor, set PM.003.Y to 0. When you are not using a Hall sensor,

install a spring or balancing unit for the Z-axis mechanical part. If the magnetic pole is detected

in the condition without a sensor, the motor slightly vibrates during the detection after the servo

is switched to the Servo On state for the first time after power on. Currently, ASDA-A3 only

supports Hall sensor of non-differential signals. Refer to Chapter 3 for the wiring of CN5

connector or Section 11.6 Position signal converter box.
