8.3.2 DOG type mechanical zero return operation
The zero return starts by the DOG type mechanical zero return operation start command. When the DOG
search function is used, the DOG type mechanical zero return becomes possible from any position.
1. Operation
1) When the DOG type mechanical zero return operation start command of the operation command is
turned from off to on, movement in the zero return direction starts at zero return speed (high speed). (The
positioning completion flag turns off.)
2) When the DOG input turns on, deceleration to the zero return speed (creep) starts.
3) When the count start point is passed, the zero-point signal count starts.
4) When the count, which is set to the zero return zero-point signal number, is reached, the operation stops.
(It outputs the CLR signal.)
5) After the zero-return completion, the set value of the zero-point address is written to the current address.
6) The positioning completion flag and the zero return completion turn on.
2. Zero return direction
Sets the zero return direction.
When BFM#3 b10/BFM#37 b10 = 0: The operation starts in the current address decreasing direction.
When BFM#3 b10/BFM#37 b10 = 1: The operation starts in the current address increasing direction.
3. DOG input polarity
The polarity of the DOG input is set.
When BFM#3 b12/BFM#37 b12 = 0: Normally-open (Operates when the DOG input is on)
When BFM#3 b12/BFM#37 b12 = 1: Normally-close (Operates when the DOG input is off)
