Dog search function
When the forward/reverse limits (BFM#26 b2, b3) are provided, zero return which uses the dog
search function can be executed.
Reverse limit
(BFM#26 b3)
1) Start position, near-point signal OFF (before passing the dog)
Operation is at the zero return speed (high speed) in the zero return direction. After the dog
is detected, speed decelerates to creep, and the PG0 signal is counted for stopping.
2) Start position, near-point signal ON
Operation is at the zero return speed in the direction opposite to the zero return direction
once, until it moves outside of the dog signal.
Hereafter, operation is at the zero return speed in the zero return direction. After the dog is
detected, speed decelerates to creep, and the PG0 signal is counted for stopping.
3) Start position, near-point signal OFF (after passing at the dog)
Operation is at the zero return speed in the zero return direction, and is decelerated and
stopped at the forward/reverse limit.
Hereafter, operation is at the zero return speed in the direction opposite to the zero return
direction. After the dog is detected, speed is decelerated and stopped.
Operation is at the zero return speed in the zero return direction again. After the dog is
detected, speed decelerates to creep, and the PG0 signal is counted for stopping.
4) When the extreme limit switch (forward limit or reverse limit) in the zero return direction is
on, it is operated at the zero return speed in the direction opposite to the zero return
direction. After the dog is detected (escaping), it is decelerated and stopped.
It is operated at the zero return speed in the zero return direction. After the dog is detected,
speed decelerates to creep, and the PG0 signal is counted for stopping.

Forced ON/OFF of CLR signal
The status of CLR signal is assigned to b7 of BFM#38.
If ON/OFF is written to the bit, the CLR signal can be forced ON/OFF.
