Chapter 3 I/O ports
Through the CN2 connector (50 pins; half pitch) the HA-655 driver communicates with a host. Details of
the I/O ports are described in this chapter.
As the functions of the pins of the connector differ in each control mode, the functions are described
separately by modes.
3-1 Position mode
3-1-1 I/O port layout
<< for incremental encoder system>>
The I/O port layout is shown as follows: ※ Do not use the pins marked “−”.
