Footnotes for the preceding table and the tables that follow:
Note1: The protection method conforms to JIC C 0920.
Note2: The applicable motor refers to Hitachi standard 3-phase motor (4p). When using other
motors, care must be taken to prevent the rated motor current (50/60Hz) from exceeding the
rated output current of the inverter.
N
ote3: The output voltage decreases as the main supply voltage decreases (except when using
the AVR function). In any case, the output voltage cannot exceed the input power supply voltage.
In any case, the output voltage cannot exceed two times the input power supply voltage
Note4: To operate the motor beyond 50/60Hz, consult the motor manufacturer for the maximum
allowable rotation speed.
Note5: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor.
Note6: The braking torque via capacitive feedback is the average deceleration torque at the
shortest deceleration (stopping from 50/60Hz as indicated). It is not continuous regenerative
braking torque. The average deceleration torque varies with motor loss. This value decreases
when operating beyond 50Hz. If a large regenerative torque is required, the optional
regenerative braking unit and a resistor should be used.
Note7: The frequency command is the maximum frequency at 9.8V for input voltage 0 to
10VDC, or at 19.6mA for input current 4 to 20mA. If this characteristic is not satisfactory for
your application, contact your Hitachi representative.
Note8: If the inverter is operated outside the region shown in the graph in the derating curve,
the inverter may be damaged or its service life may be shortened. Set B083 Carrier Frequency
Adjustment in accordance with the expected output current level. See derating curve section
for the detailed information of the inverter operating range.
Note9: The storage temperature refers to the short-term temperature during transportation.
Note10: Conforms to the test method specified in JIS JIS C 60068-2-6 :2010(IEC
60068-2-6:2007). For the model types excluded in the standard specifications, contact your
Hitachi sales representative.
Note11: Watt losses are calculated values based on specification of main semi-conductors. You
must take suitable margin when designing cabinet based on these values. Otherwise there is a
possibility of heating trouble.
Note12: “When the ambient temperature exceeds 40C, output current must be limited to the
value in ( ).

Basic System Description
A motor control system will obviously include a motor and inverter, as well as a circuit
breaker or fuses for safety. If you are connecting a motor to the inverter on a test bench
just to get started, that’s all you may need for now. But a system can also have a variety of
additional components. Some can be for noise suppression, while others may enhance the
inverter’s braking performance. The figure and table below show a system with all the
optional components you might need in your finished application.
Name Function
Breaker /
disconnect
A molded-case circuit breaker (MCCB), ground fault
interrupter (GFI), Type E Combination Motor
Controller(Type E C.M.C) or a fused disconnect device.
NOTE: The installer must refer to the NEC and local codes
to ensure safety and compliance.
Radio noise filter
Electrical noise interference may occur on nearby
equipment such as a radio receiver. This magnetic choke
filter helps reduce radiated noise (can also be used on
output).

Output-side
AC Reactor
This reactor reduces the vibration in the motor caused by
the inverter’s switching waveforms, by smoothing the
waveform to approximate commercial power quality. It is
also useful to reduce harmonics when wiring from the

Wire the Inverter Input to a Supply
In this step, you will connect wiring to the input of the inverter. This Inverter is single-phase
power only. The power connection terminals are [L1] and [N]. So you must refer to the
specifications label (on the side of the inverter) for the acceptable power source
types!
Single-phase inverter models will have no connection to the [S/L2] terminal.
This is only used for three-phase models.
Note the use of ring lug connectors is
recommended
for a secure connection.
Single-phase 100V 0.4kW
Single-phase 100V 0.75kW
NOTE: An inverter powered by a portable power generator may
cause a distorted power
waveform, overheating the generator. In general, the generator capacity should be five
times that of the inverter (kVA).

Connecting to PLCs and Other Devices
Hitachi inverters (drives) are useful in many types of applications. During installation, the
inverter keypad (or other programming device) will facilitate the initial configuration. After
installation, the inverter will generally receive its control commands through the control
logic connector or serial interface from another controlling device. In a simple application
such as single-conveyor speed control, a Run/Stop switch and potentiometer will give the
operator all the required control. In a sophisticated application, you may have a
programmable logic controller (PLC) as the system controller, with several connections to
the inverter.
It is not possible to cover all the possible types of application in this manual. It will be
necessary for you to know the electrical characteristics of the devices you want to connect
to the inverter. Then, this section and the following sections on I/O terminal functions can
help you quickly and safely connect those devices to the inverter.
CAUTION: It is possible to damage the inverter or other devices if your application
exceeds the maximum current or voltage characteristics of a connection point.
The connections between the inverter and
other devices rely on the electrical input/output
characteristics at both ends of each connection,
shown in the diagram to the right.
The inverter’s configurable inputs accept either
a sourcing or sinking output from an external
device (such as PLC). This chapter shows the
inverter’s internal electrical component(s) at
each I/O terminal. In some cases, you will
need to insert a power source in the interface
wiring.
In order to avoid equipment damage and get
your application running smoothly, we
recommend drawing a schematic of each
connection between the inverter and the other
device. Include the internal components of
each device in the schematic, so that it makes
a complete circuit loop.
After making the schematic, then:
1. Verify that the current and voltage for each
connection is within the operating limits of
each device.
2. Make sure that the logic sense (active high or active low) of any ON/OFF connection is
correct.
3. Check the zero and span (curve end points) for analog connections, and be sure the
scale factor from input to output is correct.
4. Understand what will happen at the system level if any particular device suddenly
loses power, or powers up after other devices.

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 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). If you need to change to the
source 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.
[PLC] Terminal Wiring – The [PLC]
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 [PLC] terminal and the short bar
(jumper). Locating the short bar 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 short bar
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.

Each diagram shows the connection for simple switches, or for a field device with
transistor outputs. Note that in the lower diagram, it is necessary to connect terminal [L]
only when using the field device with transistors. Be sure to use the correct connection of
the short bar shown for each wiring diagram.

The two diagrams below show input wiring circuits using an external supply. If using the
“Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the short bar,
and use a diode (*) with the external supply. This will prevent a power supply contention in
case the short bar is accidentally placed in the incorrect position. For the “Sourcing Inputs,
External Supply”, please connect the short bar as drawn in the diagram below.
