Page 33: Introduction To Variable-Frequency Drives
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. You’re probably familiar with the way a light dimmer works to vary the power sent to a light bulb, and thus the light intensity.
Page 34 1–8 Introduction to Variable-Frequency Drives An inverter, in general, is a device that converts DC power to AC power. The popular consumer power inverter is designed for powering an AC appliance from a car battery; put 12VDC in, and get 115VAC 50/60 Hz out, for example. The figure below shows how the variable-frequency drive employes an internal inverter.
Page 35 The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of switching power to the motor during all normal operations. Therefore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).
Page 36 1–10 Introduction to Variable-Frequency Drives Intelligent Functions and Parameters Much of this manual is devoted to describing how to use inverter functions and how to config- ure inverter parameters. The inverter is micropro- cessor-controlled, and has many independent functions. The microprocessor has an on-board EEPROM for parameter storage.
Page 37 1–11 SJ100 Inverter Velocity Profiles The SJ100 inverter is capable of sophisticated Speed speed control. A graphical representation of Fixed speed that capability will help you understand and program the associated parameters. This Accel Decel manual makes use of the velocity profile graph used in industry (shown at right).
Page 38: Frequently Asked Questions
Hitachi inverter. Amplifier more commonly refers to a linear amplifier for servo motor control, or a stepper motor driver IC. Finally, we use inverter to describe the Hitachi motor controller because of the way the switching electronics alternately inverts or directly couples its internal DC voltage bus to generate a variable AC output.
Page 39 For 400 V class inverters, we recommend only using a utility power source of the correct voltage. Some models of Hitachi inverters will accept either single phase or three-phase power input. How do I know which input power type to use?
Page 40 Will I be able to add dynamic (resistive) braking to my Hitachi SJ100 drive after the initial installation? Yes. The SJ100 inverter already has a dynamic braking circuit built in. Just add the resistor sized to meet the braking requirements.

Page 46: Step-By-Step Basic Installation
2–6 Step-by-Step Basic Installation Step-by-Step Basic Installation This section will guide you through the following basic steps of installation: 1. Study the warnings associated with mounting the inverter. 2. Select a suitable mounting location. 3. Place covers over the inverter’s ventilation openings to prevent debris from entering. 4.
Page 47 2–7 SJ100 Inverter Step 2: To summarize the caution messages — you will need to find a solid, non- flammable, vertical surface that is a relatively clean and dry environment. In order to ensure enough room for air circulation around the inverter to aid in cooling, maintain the specified clearance around the inverter specified in the diagram.

Page 53 2–13 SJ100 Inverter Determination of Wire and Fuse Sizes The maximum motor currents in your application determines the recommended wire size. The following table gives the wire size in AWG. The “Power Lines” column applies to the inverter input power, output wires to the motor, the earth ground connection, and any other component shown in the system wiring diagram on page 2–5.
Page 54 2–14 Step-by-Step Basic Installation Wiring the Inverter Input to a Power Supply Step 6: In this step, you will connect wiring to the input of the inverter. First, you must deter- mine whether the inverter model you have requires three-phase power only, or if it can accept either single-phase or three-phase power.
Page 55 2–15 SJ100 Inverter CAUTION: Fasten the screws with the specified fastening torque (see the following table). Check for any loosening of screws. Otherwise, there is the danger of fire. CAUTION: Remarks for using earth leakage circuit breakers in the mains supply: Frequency inverters with CE-filters (RFI-filter) and shielded (screened) motor cables have a higher leakage current toward Earth GND.
Page 56 2–16 Step-by-Step Basic Installation Wiring the Motor to the Inverter Output Step 7: The process of motor selection is beyond the scope of this manual. However, it must be an AC induction motor with three phases. It should also come with a chassis ground lug.
Page 57: Powerup Test
3. Give a brief introduction to the use of the built-in operator keypad. The powerup test gives you an important starting point to ensure a safe and successful application of the Hitachi inverter. We highly recommend performing this test before proceeding to the other chapters in this manual.
Page 58 2–18 Powerup Test CAUTION: If you operate a motor at a frequency higher than the inverter standard default setting (50Hz/60Hz), be sure to check the motor and machine specifications with the respective manufacturer. Only operate the motor at elevated frequencies after getting their approval.

Page 64 2–24 Using the Front Panel Keypad Configure the Inverter for the Number of Motor Poles- the number of magnetic poles of a motor is determined by the motor’s internal winding arrangement. The specifica- tions label on the motor usually indicates its number of poles. For proper operation, verify the parameter setting matches the motor poles.
Page 65 After using the keypad for parameter editing, it’s a good idea to switch the inverter from POWER HITACHI Program Mode to Monitor Mode and close the panel door (puts the keys for parameter editing out of sight). This will also turn out...
Page 66 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.

Page 80 3–14 “A” Group: Standard Functions NOTE: When the inverter is in SLV (sensorless vector) mode, use B83 to set the carrier frequency greater than 2.1 kHz for proper operation. When the data of the H Group parameters does not match that of the motor, satisfactory characteristics may not be obtained during sensorless vector operation.
Page 81 3–15 SJ100 Inverter DC Braking Settings The DC braking feature provides additional stopping power when compared to just a normal deceleration to a stop. DC Running Free run DC braking braking is particularly useful at the low frequency end of the deceleration ramp where there is little or no motor torque time available for stopping.
Page 82 3–16 “A” Group: Standard Functions Frequency-related Functions The inverter output generates a variable-frequency waveform that determines the motor speed (minus slip losses). You can configure the lower frequency limit to be greater than zero as shown in the graph (below left). The upper limit must not exceed the rating of the motor or capability of the machinery.
Page 83 3–17 SJ100 Inverter 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 current frequency command serves as the SP. The PID loop calculations will read the analog input for the process variable (you specify the current or voltage input) and calcu- late the output.
Page 84 3–18 “A” Group: Standard Functions 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 has an erratic power source. However, the inverter cannot boost its motor output to a voltage higher than the power input voltage.
Page 85 3–19 SJ100 Inverter Second Acceleration and Deceleration Functions The SJ100 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape, and can avoid jerk (mechanical shock) while approaching steady frequency (or stop) more gently. You can specify the frequency transition point, the point at which the standard acceleration (F02) or deceleration (F03) changes to the second acceleration (A92) or deceleration (A93).

4–2 Introduction Introduction The previous chapter gave a reference listing of all the programmable functions of the inverter. We suggest that you first scan through the previous chapter’s listing of inverter functions to gain a general familiarity. This chapter will build on that knowledge in the following ways: 1.
Page 107 4–3 SJ100 Inverter Warning Messages for Operating Procedures WARNING: Be sure to turn on the input power supply after closing the front case. While being energized, be sure not to open the front case. Otherwise, there is the danger of electric shock. WARNING: Be sure not to operate the switches with wet hands.
Page 108: Connecting To Plcs And Other Devices
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.
Page 109 4–5 SJ100 Inverter Specifications of Control and Logic Connections The control logic connectors are located just behind the front panel half-door. The relay contacts are accessible behind the main door. Connector labeling is shown below. Logic AL0 AL1 AL2 inputs Relay contacts Analog...
Page 110: Using Intelligent Input Terminals
4–6 Using Intelligent Input Terminals Using Intelligent Input Terminals Terminals 1, 2, 3, 4, 5, and 6 are identical, Inverter programmable inputs for general use. The 24VDC input circuits can use the inverter’s internal – (isolated) +24V field supply (P24) to power the inputs.
Page 111 4–7 SJ100 Inverter Multi-Speed Select The inverter provides storage parameters for up to 16 different target frequencies (speeds) that the Input Function Multi- motor output uses for steady-state run condition. speed These speeds are accessible through programming four of the intelligent terminals as binary-encoded Speed 1 inputs CF1 to CF4 per the table below.
Page 112 4–8 Using Intelligent Input Terminals Input Option Terminal Description Function Name Code Symbol State C01, C02, C03, C04, C05, C06 Valid for inputs: Example: (MSB) (LSB) Required settings: F01, A20 to A35 CF4 CF3 CF2 CF1 Notes: • When programming the multi-speed settings, be sure to press the Store key each time and then set the next multi-speed setting.
Page 113 4–9 SJ100 Inverter Jogging Command When the terminal [JG] is turned on and the [JG] Run command is issued, the inverter outputs terminal the programmed jog frequency to the motor. [FW, RV] Use a switch between terminals [JG] and (Run) [P24] to activate the JG frequency.
Page 114 4–10 Using Intelligent Input Terminals External Signal for DC Braking When the terminal [DB] is turned on, the DC Scenario 1 braking [DB] feature is enabled. Set the [FW, RV] following parameters when the external DC (Run terminal) braking terminal is to be used: [DB] terminal 1.
Page 115 4–11 SJ100 Inverter Set Second Motor If you assign the [SET] function to a logic terminal, the inverter will display the x2xx numbered parameters, allowing you to edit the second motor parameters. These parame- ters store an alternate set of motor characteristic parameters. When the terminal [SET] is turned On, the inverter will use the second set of parameters to generate the frequency output to the motor.
Page 116 4–12 Using Intelligent Input Terminals Two-stage Acceleration and Deceleration When terminal [2CH] is turned on, the Output inverter changes the rate of acceleration and frequency target frequency deceleration from the initial settings (F02 and second F03) to use the second set of acceleration/ initial deceleration values.
Page 117 4–13 SJ100 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.
Page 118 4–14 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. When the switch between the set terminals [EXT] and [P24] is turned on, the equipment enters the trip state.
Page 119 4–15 SJ100 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. To reset an alarm and restart running, turn the Run command off or perform a reset opera- tion by the terminal [RS] input or the keypad Stop/reset key.
Page 120 4–16 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 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.
Page 121 4–17 SJ100 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 the switch between the terminals [AT] and [P24] is on, it is possible to set the output frequency by applying a current input signal at [OI]-[L].
Page 122 4–18 Using Intelligent Input Terminals Reset Inverter The [RS] terminal causes the inverter to 12 ms minimum execute the reset operation. If the inverter is [RS] terminal in Trip Mode, the reset cancels the Trip state. approx. 30 ms When the switch between the set terminals [RS] and [P24] is turned on and off, the Alarm output inverter executes the reset operation.
Page 123 4–19 SJ100 Inverter PTC Thermistor Thermal Protection Motors that are equipped with a thermistor can be protected from overheating. Input terminal 5 has the unique ability to sense a thermistor voltage. When the resistance value of the thermistor connected to terminal [PTC] (5) and [L] is more than 3 k Ohms ± 10%, the inverter enters the Trip Mode, turns off the output to the motor, and indicates the trip status E35.
Page 124 4–20 Using Intelligent Input Terminals 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: •...

4–21 SJ100 Inverter 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 which 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 –...
Page 126 4–22 Using Intelligent Output Terminals Frequency Arrival Signal Frequency Arrival [FA1] and [FA2] signals indicate when the output frequency acceler- ates or decelerates to arrive at a constant frequency. Refer to the figure below. Frequency Arrival [FA1] (left graph) turns on when the output frequency gets within 0.5 Hz below or 1.5 Hz above the target constant frequency.
Page 127 4–23 SJ100 Inverter Overload Advance Notice Signal When the output current exceeds a preset Current threshold value, the [OL] terminal signal turns on. power running The parameter C41 sets the overload threshold. The overload detection circuit value regeneration operates during powered motor operation threshold and during regenerative braking.

Page 129 4–25 SJ100 Inverter Alarm Signal The inverter alarm signal is active when a fault has STOP STOP STOP 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.
Page 130 4–26 Using Intelligent Output Terminals The alarm output terminals are connected as shown below (left) by default, or after initialization. The contact logic can be inverted as shown (below right) by using the parameter setting C33. The relay contacts normally open (N.O.) and normally closed (N.O.) convention uses “normal”...
Page 131: Analog Input Operation
4–27 SJ100 Inverter Analog Input Operation The SJ100 inverters provide for analog input to command the inverter frequency output +V Ref. value. The analog input terminal group includes the L, OI, O, and H terminals on the Voltage input control connector, which provide for Voltage Current input [O] or Current [OI] input.
Page 132: Analog And Digital Monitor Output
4–28 Analog and Digital Monitor Output Analog and Digital Monitor Output In the system design for the inverter application, it is useful to monitor the inverter operation from a remote location. In some cases, this is only a panel-mounted analog meter (moving-coil type).
Page 133 4–29 SJ100 Inverter Current Monitor, PWM Signal – (C23 = 01) – The [FM] output duty cycle varies with the inverter output current to the motor. The signal period T is fixed at 4 ms, and the amplitude is fixed at 10 VDC. The signal on [FM] reaches full scale when the inverter output current reaches 200% of the rated inverter current.
Page 134: Auto-Tuning For Sensorless Vector Control
4–30 Auto-tuning for Sensorless Vector Control Auto-tuning for Sensorless Vector Control The SJ100 inverter has a built-in auto-tuning algorithm. Its purpose is to detect and record the motor parameters to use in sensorless vector control. As you may recall from Chapter 3, sensorless vector control (SLV) is the more sophisticated control algorithm the SJ100 inverter can use to deliver higher torque levels at different speeds.

Page 137: Pid Loop Operation
4–33 SJ100 Inverter PID Loop Operation In standard operation, the inverter uses a reference source selected by parameter A01 for the output frequency, which may be a fixed value (F01), a variable set by the front panel potentiometer, or value from an analog input (voltage or current). To enable PID opera- tion, set A71 = 01.
