Introduction to Variable-Frequency Drives The Purpose of Motor Speed Control for Industry Hitachi inverters provide speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor. Many applications benefit from a motor with variable speed, in several ways: •...
Inverter Input and Three-Phase Power The Hitachi SJ200 Series of inverters includes two sub-groups: the 200V class and the 400V class inverters. The drives described in this manual may be used in either the United States or Europe, although the exact voltage level for commercial power may be slightly different from country to country.
The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. There- fore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).
For loads that continuously overhaul the motor for extended periods of time, the SJ200 may not be suitable (contact your Hitachi distributor). The inverter parameters include acceleration and deceleration, which you can set to match the needs of the application. For a particular inverter, motor, and load, there will...
1–16 Introduction to Variable-Frequency Drives Velocity Profiles The SJ200 inverter is capable of sophisticated speed control. A graphical representation of Set speed Speed that capability will help you understand and configure the associated parameters. This Accel Decel manual makes use of the velocity profile graph used in industry (shown at right).
What is the “Intelligent Sensorless Vector Control” feature? Intelligent Sensorless Vector Control (iSLV) is Hitachi’s newest variable speed control technology. The original sensorless vector control (SLV) did not require motor shaft position sensors (thus “sensorless)”, but still required setting several motor parameters (either manually or through an auto-tuning procedure).
How many poles should the motor have? Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of poles, the slower the top motor speed will be, but it will have higher torque at the base speed.
Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application will require any of these options? The purpose of these noise filters is to reduce the inverter electrical noise so the operation of nearby electrical devices is not affected.

2–32 Using the Front Panel Keypad Set the Number of Motor Poles - The motor’s internal winding arrangement deter- mines its number of magnetic poles. The specifications label on the motor usually indicates the number of poles. For proper operation, verify the parameter setting matches the motor poles.
SJ200 Inverter Monitoring Parameters with the Display After using the keypad for parameter editing, it’s a good idea to switch the inverter from POWER HITACHI 5 0.0 ALARM Program Mode to Monitor Mode. The PRG HITACHI LED will be OFF, and the Hertz or Ampere LED indicates the display units.
NOTE: Some factory automation devices such as PLCs have alternate Run/Program modes; the device is in either one mode or the other. In the Hitachi inverter, however, Run Mode alternates with Stop Mode, and Program Mode alternates with Monitor Mode.
By making specific, individual changes and observing their effects, you can achieve a finely tuned system. And, the SJ200 Series inverters feature intelligent sensorless vector control (iSLV) to eliminate the need for manually setting motor parameters, or even to do an auto-tuning procedure.

3–19 SJ200 Inverter DC Braking Settings The DC braking feature can provide additional stopping torque when Running Free run DC braking compared to a normal deceleration to a stop. DC braking is particularly useful at low speeds when normal decelera- tion torque is minimal.
3–20 “A” Group: Standard Functions Frequency-related Functions Frequency Limits – Upper and lower Output limits can be imposed on the inverter frequency output frequency. These limits will apply Upper regardless of the source of the speed refer- A061 limit ence. You can configure the lower frequency limit to be greater than zero as Settable shown in the graph.
3–21 SJ200 Inverter Jump Frequencies – Some motors or machines exhibit resonances at particular speed(s), which can be destructive for prolonged running at those speeds. The inverter has up to three jump frequencies as shown in the graph. The hysteresis around the jump frequencies causes the inverter output to skip around the sensitive frequency values.
3–22 “A” Group: Standard Functions PID Control When enabled, the built-in PID loop calculates an ideal inverter output value to cause a loop feedback process variable (PV) to move closer in value to the setpoint (SP). The frequency command serves as the SP. The PID loop algorithm will read the analog input for the process variable (you specify the current or voltage input) and calculate the output.
3–23 SJ200 Inverter Automatic Voltage Regulation (AVR) Function The automatic voltage regulation (AVR) feature keeps the inverter output waveform at a relatively constant amplitude during power input fluctuations. This can be useful if the installation is subject to input voltage fluctuations. However, the inverter cannot boost its motor output to a voltage higher than the power input voltage.
3–24 “A” Group: Standard Functions Second Acceleration and Deceleration Functions The SJ200 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape.

When using the inputs to command the inverter output frequency, these parameters adjust the starting and ending ranges for the current, as well as the output frequency range.
3–28 “A” Group: Standard Functions Analog Input Calculate Function – The inverter can mathematically combine two input sources into one value. The Calculate function can either add, subtract, or multiply the two selected sources. This provides the flexibility needed by various applica- tions.You can use the result for the output frequency setting (use A001=10) or for the PID Process Variable (PV) input (use A075=03).
3–29 SJ200 Inverter ADD Frequency – The inverter can add or subtract an offset value to the output frequency setting which is specified by A001 (will work with any of the five possible sources). The ADD Frequency is a value you can store in parameter A145. The ADD Frequency is summed with or subtracted from the output frequency setting only when the [ADD] terminal is ON.
3–30 “B” Group: Fine Tuning Functions “B” Group: Fine Tuning Functions The “B” Group of functions and parameters adjust some of the more subtle but useful aspects of motor control and system configuration.

4–3 SJ200 Inverter Warning Messages for Operating Procedures Before continuing, please read the following Warning messages. WARNING: Be sure to turn ON the input power supply only after closing the front case. While the inverter is energized, be sure not to open the front case. Otherwise, there is the danger of electric shock.
Connecting to PLCs and Other Devices 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 configura- tion. After installation, the inverter will generally receive its control commands through the control logic connector or serial interface from another controlling device.
4–5 SJ200 Inverter Example Wiring Diagram The schematic diagram below provides a general example of logic connector wiring, in addition to basic power and motor wiring covered in Chapter 2.

4–9 SJ200 Inverter Using Intelligent Input Terminals Terminals , , , , , and  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.
4–10 Using Intelligent Input Terminals The two diagrams below show input wiring circuits using the inverter’s internal +24V 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.
4–11 SJ200 Inverter The two diagrams below show input wiring circuits using an external supply. If using the upper wiring diagram, be sure to use a diode with the external supply. This will prevent a power supply contention in case the SR/SK switch is accidentally placed in the incorrect position.
4–12 Using Intelligent Input Terminals Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).
4–13 SJ200 Inverter Multi-Speed Select The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for Input Function steady-state run condition. These speeds are acces- Multi- speed sible through programming four of the intelligent CF4 CF3 CF2 CF1 terminals as binary-encoded inputs CF1 to CF4 per Speed 0...

4–15 SJ200 Inverter Jogging Command The Jog input [JG] is used to command the [JG] motor to rotate slowly in small increments for manual operation. The speed is limited to [FW], [RV] 10 Hz. The frequency for the jogging opera- tion is set by parameter A038.
4–16 Using Intelligent Input Terminals External Signal for DC Braking When the terminal [DB] is turned ON, the Scenario 1 DC braking feature is enabled. Set the follow- ing parameters when the external DC braking [FW, RV] terminal [DB] is to be used: •...
4–17 SJ200 Inverter Set Second Motor If you assign the [SET] function to an intelligent input terminal, you can select between two sets of motor parameters. The second parameters store an alternate set of motor characteristics. When the terminal [SET] is turned ON, the inverter will use the second set of parameters to generate the frequency output to the motor.
4–18 Using Intelligent Input Terminals Two-stage Acceleration and Deceleration When terminal [2CH] is turned ON, the Output target inverter changes the rate of acceleration and frequency frequency deceleration from the initial settings (F002 second and F003) to use the second set of accelera- initial tion/deceleration values.
4–19 SJ200 Inverter Free-run Stop When the terminal [FRS] is turned ON, the inverter stops the output and the motor enters the free-run state (coasting). If terminal [FRS] is turned OFF, the output resumes sending power to the motor if the Run command is still active. The free-run stop feature works with other parameters to provide flexibility in stopping and starting motor rotation.
4–20 Using Intelligent Input Terminals External Trip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output. This is a general purpose interrupt type feature, and the meaning of the error depends on what you connect to the [EXT] terminal. Even if the [EXT] input is turned OFF, the inverter remains in the trip state.
4–21 SJ200 Inverter Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.
4–22 Using Intelligent Input Terminals Software Lock When the terminal [SFT] is turned ON, the data of all the parameters and functions (except the output frequency, depending on the setting of B031) is locked (prohibited from editing). When the data is locked, the keypad keys cannot edit inverter parameters. To edit parameters again, turn OFF the [SFT] terminal input.
4–23 SJ200 Inverter Analog Input Current/Voltage Select The [AT] terminal selects whether the inverter uses the voltage [O] or current [OI] input terminals for external frequency control. When intelligent input [AT] is ON, you can set the output frequency by applying a current input signal at [OI]-[L]. When the [AT] input is OFF, you can apply a voltage input signal at [O]-[L] to set the output frequency.
4–24 Using Intelligent Input Terminals Reset Inverter The [RS] terminal causes the inverter to 12 ms execute the reset operation. If the inverter is minimum in Trip Mode, the reset cancels the Trip state. [RS] When the signal [RS] is turned ON and OFF, approx.
4–25 SJ200 Inverter Thermistor Thermal Protection Motors that are equipped with a thermistor can be protected from overheating. Input terminal  has the unique ability to sense a thermistor resistance. When the resistance value of the thermistor connected to terminal [TH] (6) and [L] is more than 3 k Ω ±10%, the inverter enters the Trip Mode, turns OFF the output to the motor, and indicates the trip status E35.
4–26 Using Intelligent Input Terminals Three-wire Interface Operation The 3-wire interface is an industry standard motor control interface. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21 [STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals.
4–27 SJ200 Inverter The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensi- tive input; an OFF-to-ON transition gives the Start command. The control of direction is level-sensitive, and the direction may be changed at any time. STP (Stop Motor) is also a level-sensitive input.
4–28 Using Intelligent Input Terminals PID ON/OFF and PID Clear The PID loop function is useful for controlling motor speed to achieve constant flow, pressure, temperature, etc. in many process applications. The PID Disable function temporarily suspends PID loop execution via an intelligent input terminal. It overrides the parameter A071 (PID Enable) to stop PID execution and return to normal motor frequency output characteristics.
4–29 SJ200 Inverter Remote Control Up and Down Functions The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time of this function is same as normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate according to these principles: •...
4–30 Using Intelligent Input Terminals It is possible for the inverter to retain the frequency set from the [UP] and [DWN] termi- nals through a power loss. Parameter C101 enables/disables the memory. If disabled, the inverter retains the last frequency before an UP/DWN adjustment. Use the [UDC] terminal to clear the memory and return to the original set output frequency.
4–31 SJ200 Inverter Force Operation from Digital Operator This function permits a digital operator interface to override the following two settings in the inverter: • A001 - Frequency source setting • A002 - Run command source setting When using the [OPE] terminal input, typically A001 and A002 are configured for sources other than the digital operator interface for the output frequency and Run command sources, respectively.
4–32 Using Intelligent Input Terminals ADD Frequency Enable The inverter can add or subtract an offset value to the output frequency setting which is specified by A001 (will work with any of the five possible sources). The ADD Frequency is a value you can store in parameter A145. The ADD Frequency is summed with or subtracted from the output frequency setting only when the [ADD] terminal is ON.
4–33 SJ200 Inverter Force Terminal Mode The purpose of this intelligent input is to allow a device to force the inverter to allow control of the following two parameters via the control terminals: • A001 - Frequency source setting (01 = control terminals [FW] and [RV] •...
4–34 Using Intelligent Output Terminals Using Intelligent Output Terminals The intelligent output terminals are programmable in a similar way to the intelligent input terminals. The inverter has several output functions that you can assign individu- ally to three physical logic outputs. Two of the outputs are open-collector transistors, and the third output is the alarm relay (form C –...
4–35 SJ200 Inverter Internal Relay Output The inverter has an internal relay output with Inverter logic normally open and normally closed contacts (Type circuit board 1 form C). The output signal that controls the relay is configurable; the Alarm Signal is the default setting.
4–36 Using Intelligent Output Terminals Output Signal ON/OFF Delay Function Intelligent outputs including terminals , , and the output relay, have configurable signal transition delays. Each output can delay either the OFF-to-ON or ON-to-OFF transitions, or both. Signal transition delays are variable from 0.1 to 100.0 seconds. This feature is useful in applications that must tailor inverter output signals to meet timing requirements of certain external devices.
4–37 SJ200 Inverter Run Signal When the [RUN] signal is selected as an [FW], intelligent output terminal, the inverter [RV] outputs a signal on that terminal when it is in Run Mode. The output logic is active low, and B082 is the open collector type (switch to ground).
4–38 Using Intelligent Output Terminals Frequency Arrival Signals The Frequency Arrival group of outputs help coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
4–39 SJ200 Inverter Frequency arrival output [FA1] uses the Output standard output frequency (parameter 1.5 Hz freq. F001) as the threshold for switching. In 0.5 Hz F001 F001 the figure to the right, Frequency Arrival 1.5 Hz [FA1] turns ON when the output 0.5 Hz frequency gets within 0.5 Hz below or 1.5 Hz above the target constant...
4–40 Using Intelligent Output Terminals Overload Advance Notice Signal When the output current exceeds a preset Current threshold value, the [OL] terminal signal turns ON. C041 power running The parameter C041 sets the overload threshold. The overload detection circuit C041 regeneration operates during powered motor opera- threshold...
4–41 SJ200 Inverter Output Deviation for PID Control The PID loop error is defined as the SP, PV Process variable magnitude (absolute value) of the differ- ence between the Setpoint (target value) C044 Setpoint and the Process Variable (actual value). C044 When the error magnitude exceeds the preset value for C044, the [OD] terminal...
4–42 Using Intelligent Output Terminals Alarm Signal The inverter alarm signal is active when a fault has STOP occurred and it is in the Trip Mode (refer to the RESET Stop diagram at right). When the fault is cleared the alarm signal becomes inactive.
4–43 SJ200 Inverter The alarm relay output can be configured in two main ways: • Trip/Power Loss Alarm – The alarm relay is configured as normally closed (C036=1) by default, shown below (left). An external alarm circuit that detects broken wiring also as an alarm connects to [AL0] and [AL1].
4–44 Using Intelligent Output Terminals Analog Input Disconnect Detect This feature is useful when the inverter receives a speed reference from an external device. Upon input signal loss at either the [O] or [OI] terminal, the inverter normally just decelerates the motor to a stop. However, the inverter can use the intelligent output terminal [Dc] to signal other machinery that a signal loss has occurred.
4–45 SJ200 Inverter PID Second Stage Output The inverter has a built-in PID loop feature for two-stage control, useful for certain applications such as building ventilation or heating and cooling (HVAC). In an ideal control environment, a single PID loop controller (stage) would be adequate. However, in certain conditions, the maximum output energy from the first stage is not enough to maintain the Process Variable (PV) at or near the Setpoint (SP).
4–46 Using Intelligent Output Terminals To use the PID Second Stage Output feature, you will need to choose upper and lower limits for the PV, via C053 and C052 respectively. As the timing diagram below shows, these are the thresholds Stage #1 inverter uses to turn ON or OFF Stage #2 inverter via the [FBV] output.

4–48 Using Intelligent Output Terminals Network Detection Signal The Network Detection Signal output indicates the general status of network communi- cations. The inverter has a programmable watchdog timer to monitor network activity. Parameter C077 sets the time-out period. If communications stop or pause longer than the specified time-out period, the Ndc output turns ON.
4–49 SJ200 Inverter Master Slave Watchdog timer Time-out C077 =xx.xx sec. [NDc] Alarm C076 =00 or 01 Logic Output Function The Logic Output Function uses the inverter’s built-in logic feature. You can select any two of the other nine intelligent output options for internal inputs (use C141 and C142). Then, use C143 to configure the logic function to apply the logical AND, OR, or XOR (exclusive OR) operator as desired to the two inputs.

4–52 Analog Input Operation The following table shows the available analog input settings. Parameter A005 and the input terminal [AT] determine the External Frequency Command input terminals that are available, and how they function. The analog inputs [O] and [OI] use terminal [L] as the reference (signal return).
4–53 SJ200 Inverter Analog Output Operation In inverter applications it is useful to monitor H O OI AM CM2 12 11 the inverter operation from a remote location or – from the front panel of an inverter enclosure. In Analog A GND some cases, this requires only a panel-mounted Voltage Output...
4–54 PID Loop Operation PID Loop Operation In standard operation, the inverter uses a reference source selected by parameter A001 for the output frequency, which may be a fixed value (F001), a variable set by the front panel potentiometer, or value from an analog input (voltage or current). To enable PID operation, set A071 = 01.
4–55 SJ200 Inverter PID Loop Configuration The inverter’s PID loop algorithm is configurable for various applications. PID Output Limit - The PID loop controller has a built-in output limit function. This function monitors the difference between the PID setpoint and the loop output (inverter output frequency), measured as a percentage of the full scale range of each.
4–56 Configuring the Inverter for Multiple Motors Configuring the Inverter for Multiple Motors Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single inverter’s output. For example, this is common in conveyor applications where two separate conveyors need to SJ200 have approximately the same speed.
4–57 SJ200 Inverter Having two motor profiles lets you store two “personalities” for motors in one inverter’s memory. The inverter allows the final selection between the two motor types to be made in the field through the use of an intelligent input terminal function [SET]. This provides an extra level of flexibility needed in particular situations.

B–4 Connecting the Inverter to ModBus 4. Terminate Network Wiring - The RS-485 wiring must be terminated at each physical end to suppress electrical reflections and help decrease transmission errors. The SJ200 communications port does not include a termination resistor. Therefore, you will need to add termination to the inverter if it is at the end of the network wiring.
B–5 SJ200 Inverter 6. Inverter Parameter Setup - The inverter has several settings related to ModBus communications. The table below lists them together. The Required column indicates which parameters must be set properly to allow communications. You may need to refer to the host computer documentation in order to match some of its settings.
