Page 43: Frequently Asked Questions

1−23 Frequently Asked Questions Q. What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? A. An inverter can vary the motor speed with very little loss of efficiency, unlike mechanical or hydraulic speed control solutions. The resulting energy savings usually pays for the inverter in a relatively short time.
Page 44

Q. How many poles should the motor have? A. Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of the poles, the slower the top motor speed will be, but it will have higher torque at the base speed.
Page 45

This is a physics question that may be answered either empirically or through extensive calculations. Q. Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application require any of these options? A.

3−15 Basic Parameter Settings These settings affect the most fundamental behavior of the inverter – the outputs to the motor. The frequency of the inverter’s AC output determines the motor speed. You may select from three different sources for the reference speed. During application development you may prefer using the potentiometer, but you may switch to an external source (control terminal setting) in the finished application, for example.
Page 97

3−16 Analog Input Settings The inverter has the capability to accept an external analog input that can command the output frequency to the motor. Voltage input (0-10 V) and current input (4-20mA) are available on separate terminals ([O] and [OI] respectively). Terminal [L] serves as signal ground for the two analog inputs.

3−21 Jog Frequency – The jog speed setting is used whenever the Jog command is active. The jog speed setting range is arbitrarily limited to 10 Hz, to provide safety during manual operation. The acceleration to the jog frequency is instantaneous, but you can choose from three modes for the best method for stopping the jog operation.
Page 103

3−22 Torque Control Algorithms Inverter Torque Control Algorithms The inverter generates the motor output according algorithm selected. V/F control constant torque (V/F-VC) Parameter A044 selects the inverter algorithm A044 for generating the frequency output, as shown in V/F control, variable (1.7) torque the diagram to the right (A244 for 2nd motor).

3−28 Frequency-related Functions Frequency Limits – Upper and lower Output limits can be imposed on the inverter frequency output frequency. These limits will Upper A061 apply regardless of the source of the limit speed reference. You can configure the Settable lower frequency limit to be greater than range zero as shown in the graph.
Page 110

3−29 Jump Frequencies – Some motors or machines exhibit resonances at particular speed(s), which can be destructive for prolonged running at those speeds. The inverter jump frequencies has up to three as shown in the graph. The hysteresis around the jump frequencies causes the inverter output to skip around the sensitive frequency values.
Page 111

3−30 Acceleration stop/Deceleration stop – The acceleration stop and deceleration stop frequency setting allows you to make the inverter wait, upon starting the motor or upon decelerating the motor, until the motor slip becomes less when the motor load causes a large moment of inertia.
Page 112: Pid Control

3−31 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 set point (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.
Page 113

3−32 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.
Page 114

3−33 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.

3−35 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.
Page 117

3−36 Energy Savings Mode / Optional Accel/Decel Energy Saving Mode – This function allows the inverter to deliver the minimum power necessary to maintain speed at any given frequency. This works best when driving variable torque characteristic loads such as fans and pumps. Parameter A085=01 enables this function and A086 controls the degrees of its effect.
Page 118

3−37 Second Acceleration and Deceleration Functions The WJ200 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape. You can specify the frequency transition point, the point at which the standard acceleration (F002) or deceleration (F003) changes to the second acceleration (a092) or deceleration (a093).

Additional Analog Input Settings Input Range Settings – The parameters in the following table adjust the input characteristics of the analog current input.
Page 122

3−41 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 applications. You can use the result for the output frequency setting (use A001=10) or for the PID Process Variable (PV) input (use A075=03).
Page 123

3−42 Add Frequency – The inverter can add or subtract on 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.

Page 215: Using Intelligent Input Terminals

4−12 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.
Page 216

4−13 The two diagrams below 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.
Page 217

4−14 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.
Page 218

4−15 The power to the inverter control part can be supplied externally as shown below. Except driving motor, it is possible read and write the parameters by keypad and via communication even the drive itself is not powered. WJ200 By having ability inverter doesn’t block the current flowing into itself when it is not powered.

Page 226: Free-run Stop

4−23 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 227: External Trip

4−24 External Trip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code 12, 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.
Page 228: Unattended Start Protection

4−25 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 will not prevents that automatic startup, so that the inverter run without outside intervention.

4−28 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.
Page 232: Reset Inverter

Page 413

D−2 CE-EMC Installation Guidelines You are required to satisfy the EMC directive (2004/108/EC) when using an WJ200 inverter in an EU country. To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC filter suitable for each model, and follow the guidelines in this section. Following table shows the compliance condition for reference.
Page 414

D−3 3. As user you must ensure that the HF (high frequency) impedance between adjustable frequency inverter, filter, and ground is as small as possible. • Ensure that the connections are metallic and have the largest possible contact areas (zinc-plated mounting plates). 4.
Page 415

D−4 8. Follow safety measures in the filter installation. • If using external EMC filter, ensure that the ground terminal (PE) of the filter is properly connected to the ground terminal of the adjustable frequency inverter. An HF ground connection via metal contact between the housings of the filter and the adjustable frequency inverter, or solely via cable shield, is not permitted as a protective conductor connection.
Page 416

D−5 Installation for WJ200 series (example of SFE models) Model LFx (3-ph. 200V class) and HFx (3-ph. 400V class) are the same concept for the installation. Power supply 1-ph. 200V Metal plate (earth) The filter is a footprint type, so it is located between the inverter and the metal plate.
Page 417: Hitachi Emc Recommendations

D−6 Hitachi EMC Recommendations WARNING: This equipment should be installed, adjusted, and serviced by qualified personal familiar with construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury. Use the following checklist to ensure the inverter is within proper operating ranges and conditions.
