NOTE: The system manufacturer is responsible fo r selecting the level of risk factors in 
accordance with EN954-1. (Stop categories are defined by EN60204-1.)
Wiring ExamplesThe examples of wiring shown below are based  on the three stop categories compliant with 
European Machinery Directive EN60204-1.
 Category 0: (Uncontrolled) stopping by immedi ate removal of power to machine actuators
 Category 1: Stopping by removal of power af ter controlled stopping with power to machine 
actuators retained
 Category 2: Controlled stopping with  power to machine actuators retained
NOTE: The Safe Stop function must be activated  at least once a year for preventive 
maintenance purposes.
NOTE: Before preventive maintenance, the machine must be turned off. If the power supply to 
the motor is not turned off during testing, the Sa fe Stop function will not operate. In such case, 
the inverter must be replaced.
The examples of wiring below are intended to implement the Safe Stop function through safety 
input of the EMR signal by the method complying with EN954-1 Category 3.
 The emergency stop circuit is monitored via an external safety relay (safety switching 
device).
 One safety relay (safety switching devi ce) can be used for multiple inverters.
3 The requirements of category B and proven 
safety principle specifications must be applied. 
Safety-related parts must  be designed to meet 
the following requirements:
• The safety function always operates when a 
single defect (fault) occurs.
•  Each single defect (fault) is eventually 
detected to prevent the loss of the safety 
function. •
The safety function always 
operates when a single defect 
(fault) occurs.
• Almost all defects (faults) are 
detected.
• Accumulation of undetected 
defects (faults) may cause a 
loss of the safety function.

 S13  Emergency stop button – Switches the inve rter into safe stop mode and the motor into 
free-running status
 S14  Start/stop button – Switches  the inverter into safe stop mode by [EMR] signal input to a 
digital input terminal and sets the motor into free-running status. (This operation corre-
sponds to EN60204-1 Stop Category 0.)
 Safe stop mode continues as long as the [EMR]  signal is input or until the [RS] signal is 
input even after the [EMR] signal is canceled.
 To use the inverter for an application in wh ich a mechanical brake (such as a crane or 
elevator) must be contro lled, the safety output from an external safety relay must be serially 
connected to the brake control circuit.
NOTE: The cables used for safety relay wiring,  the EMR signal, and RS signal must be 
shielded coaxial cables, such as type RG174/ U complying with MIL-C17 (made by LAPP) or 
KX3B complying with NF C 93-550. Each cable mu st be 2.8 mm in outer diameter and 2 m or 
less in length. The cable shielding must be grounded.
NOTE: Every inductor-related device, such as a relay or contactor, must have an over-voltage 
protection circuit.

Choosing a Programming Device
IntroductionHitachi variable frequency  drives (inverters) use the latest el ectronics technology for getting the 
right AC waveform to the motor at the right  time. The benefits are many, including energy 
savings and higher machine output  or productivity. The flexibility required to handle a broad 
range of applications has required ever more configurable options and parameters—inverters 
are now a complex industrial automation componen t. And this can make a product seem diffi-
cult to use, but the goal of this chapter is to make this easier for you.
As the powerup test in Chapter 2 demonstrate d, you do not have to program very many param-
eters to run the motor. In fact, most applicat ions would benefit only from programming just a 
few, specific parameters. This chapter will expl ain the purpose of each set of parameters, and 
help you choose the ones that ar e important to your application.
If you are developing a new application for the in verter and a motor, finding the right parame-
ters to change is mostly an exercise in optimi zation. Therefore, it is okay to begin running the 
motor with a loosely tuned system. By making sp ecific, individual changes and observing their 
effects, you can achieve a fine ly tuned system. And, the SJ700
2 Series inverters have a built-in 
auto-tuning algorithm to set certain motor parameters.
Inverter
Programming
KeypadsThe front panel keypad is the first and best way  to get to know the inverter’s capabilities. Every 
function or programmable parameter is accessibl e from the keypad. All keypads have the same 
basic layout, but with different features. The  OPE–SRE has a potentiometer knob for frequency 
setting input. The SRW–0EX Read/write Copy Un it has the ability to upload (copy) or 
download (write) all inverter parameter data to/from memory in the copy unit itself. This unit is 
useful in transferring one inve rter’s settings to another.
The following table shows various programming  options, the features unique to each device, 
and the cables required.
TIP:  Other special-purpose keypads are available, such as ones to serve the needs of the HVAC 
market (heating, ventilating & air conditioning) . Please contact your Hitachi distributor for 
details.

Using Keypad Devices
Inverter Front 
Panel KeypadThe SJ7002 Series inverter front ke ypad contains all the elemen ts for both monitoring and 
programming parameters. The keypad layout  (OPE–SRE) is shown below. All other 
programming devices for the inverter have  a similar key arrangement and function.
Key and
Indicator LegendRun/Stop LED  – ON when the inverter output is ON and the motor is developing torque, 
and OFF when the inverter output is OFF (Stop Mode).
 Program/Monitor LED  – This LED is ON when the inverter is ready for  parameter editing 
(Program Mode). It is normally OFF when  the parameter display is monitoring data 
(Monitor Mode). However, the PRG LED will be ON whenever you are monitoring the 
value of parameter D001. (When the keypad  is enabled as the frequency source via 
A001=02, you can edit the inverter frequency di rectly from D001 monitor display by using 
the Up/Down keys.)
 Run Key  – Press this key to run the motor (the R un Enable LED must be ON first). Parame-
ter F004, Keypad Run Key Routing, determines  whether the Run key generates a Run FWD 
or Run REV command.
 Run Key Enable LED  – is ON when the inverter is ready to respond to the Run key, OFF 
when the Run key is disabled.
 Stop/Reset Key  – Press this key to stop the motor when it is running (uses the programmed 
deceleration rate). This key will also reset an alarm that has tripped.
 Potentiometer  (OPE–SRE only) – allows an operator to directly set the motor speed when 
the potentiometer is enabled for output frequency control
 Potentiometer Enable LED  – ON when the potentiometer is enabled for value entry
(OPE–SRE only).
 Parameter Display  – a 4-digit, 7-segment display fo r parameters and function codes.
 Display Units: Hertz/Volts/Amperes /kW/% – These LEDs indicate the units associated 
with the parameter display. When the displa y is monitoring a parameter, the appropriate 
LED is ON. In the case of kW units, both  Volts and Amperes LEDs will be ON. An easy 
way to remember this is that kW = (V x A)/1000.
 Power LED  – This LED is ON when the power input to the inverter is ON.
 Alarm LED  – This LED is ON when an alarm condition has tripped the inverter. Clearing 
the alarm will turn this LED OFF again. See Chapter 6 for details on clearing alarms.
 Function Key  – This key is used to navigate throu gh the lists of parameters and functions 
for setting and monitori ng parameter values.
 Up/Down ( , ) Keys – Use these keys to alternately move up or down the lists of 
parameter and f unctions shown in the display, and increment/decrement values.
 Store (   ) Key  – When the unit is in Program Mode and the operator has edited a param-
eter value, press the Store key to write the new value to the EEPROM. This parameter is then 
displayed at powerup by default. If you want to  change the powerup default, navigate to a 
new parameter value and press the Store key.

Configuring Drive Parameters

Operational 
ModesThe RUN and PGM LEDs tell  just part of the story; 
Run Mode and Program  Modes are independent 
modes, not opposite modes. In the state diagram to 
the right, Run alternates with Stop, and Program 
Mode alternates with Monitor Mode. This is a very 
important ability, for it shows that a technician can 
approach a running machine and change some 
parameters without shu tting down the machine.
The occurrence of a faul t during operation will 
cause the inverter to enter the Trip Mode as shown. 
An event such as an output overload will cause the 
inverter to exit the Run Mode and turn OFF its 
output to the motor. In the Trip Mode, any request 
to run the motor is ignored. You must clear the 
error by pressing the Stop/Reset switch. See 
“
Monitoring Trip Events, History, & Conditions” 
on page 6–5.
Run Mode EditsThe inverter can be in Run Mode (inverter output is controlling motor) and still allow you to 
edit certain parameters. This is useful in applic ations that must run continuously, yet need some 
inverter parameter adjustment.
The parameter tables in this chapte r have a column titled “Run Mode 
Edit.” An Ex mark  ✘ means the parameter cannot be edited; a Check 
mark  ✔ means the parameter can be edited. You’ll notice in the table 
example to the right the two adjacent marks: “ ✘ ✔”. The two marks 
(that can also be “ ✘ ✘” or “✔ ✔”) correspond to these levels of access 
to editing:
 Low-access level to Run  Mode edits (indicated by left-most mark)
 High-access level to Run Mode edits (indicated by  right-most mark)
The Software Lock Setting (parameter B031) dete rmines the particular access level that is in 
effect during Run Mode and access in other condit ions, as well. It is the responsibility of the 
user to choose a useful and safe software lock setting for the inverter operating conditions and 
personnel. Please refer to  “
Software Lock Mode” on page 3–38 for more information.
Control 
AlgorithmsThe motor control program in the SJ7002 
inverter has several sinusoidal PWM 
switching algorithms. The intent is that you 
select the best algor ithm for the motor 
characteristics in yo ur application. Each 
algorithm generates the frequency output in 
a unique way. Once configured, the 
algorithm is the basis for other parameter 
settings as well (see  “
Torque Control 
Algorithms” on page 3–14). Therefore, 
choose the best algorithm early in your 
application de sign process.
