A. The initial direction is reverse (CW). The motor operates at the switch search
speed.
B. When the negative limit switch (NOT) is on, the motor decelerates and stops.
Then, the motor operates forward (CCW) at the switch search speed.
C. When the Negative Home Switch is on, the motor decelerates to Zero search
speed. Then the direction changes to reverse (CW).
D. While operating at Zero search speed, the first index pulse is detected, and the
motor rotates to the index position (Home).
The homing sequences of Methods 11, 12, 13 above are almost identical to those of
Method 14 explained above, except for differences in initial direction and actions pertaining
to Home switch positivity/negativity.
Method 24
The initial direction is forward (CCW), and the position where the Positive Home Switch is
on becomes the home position home position.
