 Mode 17 Homing which depends on the negative limit switch
Circumstance 1： MC_Home instruction is executed when the negative limit switch is OFF and the axis
moves in the negative direction at the first-phase speed. The motion direction
changes and the axis moves at the second-phase speed when the axis encounters
that the negative limit switch is ON. Where the servo is when the negative limit switch
is OFF is the home position.
Circumstance 2： MC_Home instruction is executed when the negative limit switch is ON and the axis
moves in the positive direction at the second-phase speed. Where the servo is is the
home position when the negative limit switch is OFF.
