4.6 Control via External Control I/O Connector
BP4610 4-51
4.6 Control via External Control I/O Connector
Output on/off and sequence execution can be controlled by inputting digital signals to the external
control I/O connector. The step sync output signal is output from the external I/O connector.
The status of the BP4610 can also be monitored by reading the output signal from the external control
I/O connector.
( Refer to “2.4.4 Connection to external control I/O connector”.)
Table 4-20 lists the functions of each pin.
