About the home-position detection modes
There are two operation modes for mechanical home seeking: the two-sensor mode (constant-speed
operation) and the three-sensor mode (high-speed operation).
Choose the mode according to the number of sensors installed in the system.
2-sensor mode
Uses two sensors, +LS and -LS, and returns to the
mechanical home at the starting speed (VS).
Mechanical home will be either +LS or -LS.
3-sensor mode
Uses three sensors: +LS, -LS and HOMELS. Since there
are three sensors checking the location of the motor, high-
speed return to the mechanical home position is possible
regardless of the motor's position.
Under the three-sensor mode, HOMELS is the mechanical
home position
