(A) Since the home signal is on, the drive operates at the switch search speed in the direction of the positive home switch
(CCW). It might not reach the Switch Search Speed depending on the start position of homing.
(B) When the Home switch is turned off, the drive will decelerate to zero search speed, and then continue to operate.
(C) While operating at the zero search speed, the drive detects the first index pulse to move to the index position (Home).

(A) The initial driving direction is positive (CCW), and the drive operates at the switch search speed.
(B) When the positive limit switch (POT) is turned on, the drive will decelerate to a stop, and then operate at switch search
speed in the negative direction (CW).
(C) When the positive home switch is turned off, the drive decelerates to the zero search speed, then continues to operate.
(D) While operating at the zero search speed, the drive detects the first index pulse to move to the index position (Home).
Methods 8, 9, and 10 are nearly identical to method 7 in terms of homing sequence. The only differences are the initial
driving direction and the home switch polarity.
The positive home switch is determined by the initial driving direction. The home switch encountered in the
initial driving direction becomes the positive home switch.
