Using Intelligent Input Terminals

Terminals [1], [2], [3], [4], [5], [6] and [7] 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 WJ200 inverter features selectable
to the connection to the external switching device–it either
input 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 jumper wire for
configuring
sourcing inputs. To access it, you must
remove the front cover of the inverter
housing. In the figure to the top right, the
jumper wire 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 jumper wire 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 jumper wire
position. Otherwise, damage to the inverter circuitry may occur.
[PLC] Terminal Wiring – The [PLC]
terminal (Programmable Logic Control
terminal) is named to include various
devices
inverter's logic inputs. In the figure to
the right, note the [PLC] terminal and
the jumper wire. Locating the jumper
wire between [PLC] 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 jumper wire between [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.
