3.4.11 Drive Control Terminals
Definitions of the drive terminals are summarized in Table 3.16.
•
•
Connector 1 provides four digital inputs; two selectable digital inputs or outputs, 24 V DC terminal supply voltage, and a common for optional customer supplied 24 V DC voltage.
Serial communications use
130BX231.10
•
Connector 3 provides two analog inputs, one analog output, 10 V DC supply voltage, and commons for the inputs and output.
