Using Intelligent Input Terminals

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 or an
external power supply. This section describes input circuits operation and how to
connect them properly to switches or transistor outputs on field devices.

The X200 inverter features selectable

sinking

or

sourcing

inputs. These terms refer to

the connection to the external switching device–it either

sinks

current (from the input

to GND) or

sources

current (from a power source) into the input. Note that the

sink/source naming convention may be different in your particular country or industry.
In any case, just follow the wiring diagrams in this section for your application.

The inverter has a short bar (jumper) for
configuring the choice of sinking or sourcing
inputs. To access it, you must remove the
front cover of the inverter housing. In the
figure to the top right, the short bar is
shown as attached to the logic terminal
block (connector). For EU and US version
(suffix –xFE, and –xFU), it is originally
located as source type logic. If you need to
change to the sink type connection, remove
the short bar and connect it as shown in the
figure at the bottom right.

CAUTION: Be sure to turn OFF power to the inverter before changing the short circuit
bar position. Otherwise, damage to the inverter circuitry may occur.

[

PCS

] Terminal Wiring – The [

PCS

]

terminal (Programmable Logic Control
terminal) is named to include various
devices that can connect to the
inverter’s logic inputs. In the figure to
the right, note the [

PCS

] terminal and

the short bar (jumper). Locating the
short bar between [

PCS

] and [L] sets the

input logic source type, which is the
default setting for EU and US versions.
In this case, you connect input terminal
to [P24] to make it active. If instead you
locate the short bar between [

PCS

] and

[P24], the input logic will be sink type.
In this case, you connect the input
terminal to [L] to make it active.

The wiring diagram on the following pages show the four combinations of using
sourcing or sinking inputs, and using the internal or an external DC supply.
