Control Logic Signal Specifications

The control logic connectors are located just
behind the front housing cover. The relay
contacts are just to the left of the logic connectors.
Connector labeling is shown below.

The two terminals [L] are electrically connected together inside the inverter.
We recommend using [L] logic GND (to the right) for logic input circuits and
[L] analog GND (to the left) for analog I/O circuits.
Default relay N.O./N.C. configuration is reversed. See

output
2 1 L PCS P24 CM2 11
Short bar : default position (Source logic)
24VDC, 30mA. (do not short to terminal L)
Factory set: Source type for –FE and –HE
models (connecting [P24] to [1]~[5] turns
each input ON). To change to sink type,
remove the short wire between [PCS] and
[L], and connect it between [P24] and [L]. In
this case, connecting [L] to [1]~[5] makes
each input ON.
27VDC max. (use PCS or an external
supply referenced to terminal L)
Sum of input [1]~[5] currents (return)
50mA max. ON state current,
27 VDC max. OFF state voltage

Sum of [OI], [O], and [H] currents (return)
4 to 19.6 mA range, 20 mA nominal,
