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
the connection to the external switching device–it either
to GND) or
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 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
(connector). For EU and US version (suffix
–xFE, and –xFU), it is originally located as
source type logic. If you need to change it to
the sink type connection, remove the short
bar and connect it as shown in figure at
right (bottom).
CAUTION: Be sure to turn OFF power to the inverter before changing the short circuit
bar position to change SR/SK. Otherwise, damage to the inverter circuitry may occur.
[PLC] Terminal Wiring – The [PLC]
terminal
System terminal) is named to include
various devices that can connect to the
inverter's logic inputs. In the figure to
the right, note the PLC terminal and the
nearby short bar. Locating the short bar
at [PLC] and [L] makes the input logic
to source type, which is the default set
for EU and US versions. In this case,
you connect input terminal to [P24] to
make it active. And if you locate the
short bar at [PLC] 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.
