Using Intelligent Input Terminals
Using Intelligent Input Terminals
Operations and Monitoring
Terminals [1], [2], [3], [4], and [5] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply (P24) to power the inputs. The input circuits are internally connected to the power supply ground. As the diagram shows, you can use a switch (or jumper) to activate an input terminal that has been configured.
If you use an external supply, its GND terminal must connect to the [L] terminal on the inverter to complete the input circuit. Current can only flow into each input, so they are sinking inputs, whether powered internally or externally.
NOTE: We recommend using the top row [L] logic GND for logic input circuits and the [L] GND on the bottom row of terminals for analog I/O circuits.
