About the home-position detection modes
There are two operation modes for mechanical home seeking: the 2-sensor mode (constant-speed
operation) and the 3-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 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
