For DOG terminal, STOP terminal

In each operation mode, various inputs are connected to the DOG terminal and the STOP terminal.
The DOG terminal is used for the DOG input for the mechanical zero return operation, and for the interrupt
input 0 for the external command positioning operation, the interrupt 1-speed positioning operation, the
interrupt stop operation, and the interrupt 2-speed positioning operation.
The STOP terminal is used for the decelerate stop input, the external command positioning operation, and the
interrupt input 1 for the interrupt 2-speed positioning operation. In addition, ON/OFF polarities of these inputs
invert depending on the setting of the DOG input polarity (b12) and the STOP input polarity (b14) of BFM#3/
BFM#37.
Examples of connections which express the above description are shown below.
Operation mode selection indicates the operation mode to be used. Interrupt signal indicates the signals used
in the given operation mode.
