CAUTION: Remarks for using ground fault interrupter breakers in the main power supply: Adjustable frequency inverters with CE-filters (RFIfilter) and shielded (screened) motor cables have a higher leakage current toward Earth GND. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters. Because of the rectifier on the input side of the inv erter there is the possibility to stall the switch-off function through small amounts of DC current. Please observe the following: • Use only short time-invariant and pulse current-sensitive ground fault interrupters with higher trigger current. • Other components should be secured with separate ground fault interrupters. • Ground fault interrupters in the power input wiring of an inverter are not an absolute protection against electric shock.

CAUTION: Be sure to install a fuse in each phase of the main power supply to the inverter. Otherwise, there is the danger of fire.

CAUTION: For motor leads, ground fault interrupter breakers and electromagnetic contactors, be sure to size these components properly (each must have the capacity for rated current and voltage). Otherwise, there is the danger of fire.

Powerup Test Caution Messages

..... 2–19

CAUTION: The heat sink fins will have a high temperature. Be careful not to touch them. Otherwise, there is the danger of getting burned.

CAUTION: The operation of the inverter can be easily changed from low speed to high speed. Be sure to check the capability and limitations of the motor and machine before operating the inverter. Otherwise, there is the danger of injury.

CAUTION: If you operate a motor at a frequency higher than the in v erter 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. Otherwise, there is the danger of equipment damage and/or injury.

CAUTION: Check the following before and during the powerup test. Otherwise, there is the danger of equipment damage. • Is the shorting bar between the [+1] and [+] terminals installed? DO NOT power or operate the inverter if the jumper is removed. • Is the direction of the motor rotation correct? • Did the inverter trip during acceleration or deceleration? • Were the rpm and frequency meter readings as expected? • Were there any abnormal motor vibrations or noise?

Warnings for Configuring Drive Parameters

L200 Inverter

vii

WARNING: When parameter B012, level of electronic thermal setting, is set to motor FLA rating (Full Load Ampere nameplate rating), the inverter provides solid state motor overload protection at 115% of motor FLA or equivalent. If parameter B012 e xceeds the motor FLA rating, the motor may overheat and be damaged. Parameter B012, le v el of electronic thermal setting, is a variable parameter.

Cautions for Configuring Drive Parameters

CAUTION: Be careful to avoid specifying a braking time that is long enough to cause motor overheating. If you use DC braking, we recommend using a motor with a built-in thermistor, and wiring it to the inverter’s thermistor input (see “Thermistor Thermal Protection” on page 4–25). Also refer to the motor manufacturer’s specifications for duty-cycle recommendations during DC braking.

Warnings for Operations and Monitoring

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.

.... 3–33

.... 3–20

...... 4–3

WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise, there is the danger of electric shock.

WARNING: While the inverter is energized, be sure not to touch the inverter terminals e ven when the motor is stopped. Otherwise, there is the danger of electric shock.

WARNING: If the Retry Mode is selected, the motor may suddenly restart after a trip stop. Be sure to stop the inv erter before approaching the machine (be sure to design the machine so that safety for personnel is secure even if it restarts.) Otherwise, it may cause injury to personnel.

WARNING: If the power supply is cut OFF for a short period of time, the inverter may restart operation after the power supply recovers if the Run command is active. If a restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power recovery. Otherwise, it may cause injury to personnel.

WARNING: The Stop Key is effective only when the Stop function is enabled. Be sure to enable the Stop Key separately from the emergency stop. Otherwise, it may cause injury to personnel.

WARNING: During a trip event, if the alarm reset is applied and the Run command is present, the inverter will automatically restart. Be sure to apply the alarm reset only after verifying the Run command is OFF. Otherwise, it may cause injury to personnel.

WARNING: Be sure not to touch the inside of the energized inverter or to put any conductive object into it. Otherwise, there is a danger of electric shock and/or fire.

WARNING: If power is turned ON when the Run command is already active, the motor will automatically start and injury may result. Before turning ON the power, confirm that the RUN command is not present.

WARNING: When the Stop key function is disabled, pressing the Stop key does not stop the inverter, nor will it reset a trip alarm.

WARNING: Be sure to provide a separate, hard-wired emergency stop switch when the application warrants it.

WARNING: If the power is turned ON and the Run command is already active, the motor starts rotation and is dangerous! Before turning power ON, confirm that the Run command is not active.

WARNING: After the Reset command is given and the alarm reset occurs, the motor will restart suddenly if the Run command is already active. Be sure to set the alarm reset after verifying that the Run command is OFF to prevent injury to personnel.

General Warnings and Cautions

WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/ or injury.

CAUTION: Withstand voltage tests and insulation resistance tests (HIPOT) are executed before the units are shipped, so there is no need to conduct these tests before operation.

CAUTION: Do not attach or remove wiring or connectors when power is applied. Also, do not check signals during operation.

CAUTION: Be sure to connect the grounding terminal to earth ground.

CAUTION: When inspecting the unit, be sure to wait five minutes after tuning OFF the

power supply before opening the cover.

When there has been a sudden power failure while an operation instruction is acti v e, then the unit may restart operation automatically after the power failure has ended. If there is a possibility that such an occurrence may harm humans, then install an electromagnetic contactor (Mgo) on the power supply side, so that the circuit does not allow automatic restarting after the power supply recov ers. If the optional remote operator is used and the retry function has been selected, this will also cause automatic restarting when a Run command is active. So, please be careful.

CAUTION: Do not insert leading power factor capacitors or surge absorbers between the output terminals of the inverter and motor.

CAUTION: MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER (For the 400 V CLASS)

In a system using an inverter with the voltage control PWM system, a voltage surge caused by the cable constants such as the cable length (especially when the distance between the motor and inverter is 10 m or more) and cabling method may occur at the motor terminals. A dedicated filter of the 400 V class for suppressing this voltage surge is available. Be sure to install a filter in this situation.

Page 13

L200 Inverter

CAUTION: EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTER

In the cases below in v olving a general-purpose inverter, a lar ge peak current can flow on the power supply side, sometimes destroying the converter module:

1. The unbalance factor of the power supply is 3% or higher.

2. The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500 kVA or more).

3. Abrupt power supply changes are expected, due to conditions such as: a. Several inverters are interconnected with a short bus. b. A thyristor converter and an inverter are interconnected with a short bus. c. An installed phase advance capacitor opens and closes.

Where these conditions exist or when the connected equipment must be highly reliable, you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current) with respect to the supply voltage on the po wer supply sid e. Also, where the effects of an indirect lightning strike are possible, install a lightning conductor.

CAUTION: SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER

The inverter uses many semiconductor switching elements such as transistors and IGBTs. Thus, a radio receiver or measuring instrument located near the inverter is susceptible to noise interference. To protect the instruments from erroneous operation due to noise interference, they should be used well away from the inverter. It is also effective to shield the whole inverter structure. The addition of an EMI filter on the input side of the inverter also reduces the effect of noise from the commercial power line on external devices. Note that the external dispersion of noise from the power line can be minimized by connecting an EMI filter on the primary side of inverter.

CAUTION: When the EEPROM error E08 occurs, be sure to confirm th e setting values again.

CAUTION: When using normally closed active state settings (C011 to C015) for exter- nally commanded Forward or Reverse terminals [FW] or [RV], the inverter may start automatically when the external system is powered OFF or disconnected from the inverter! So, do not use normally closed active state settings for Forward or Reverse terminals [FW] or [RV] unless your system design protects against unintended motor operation.

CAUTION: In all the illustrations in this manual, covers and safety devices are occasionally removed to describe the details. While operating the product, make sure that the covers and safety devices are placed as they were specified originally and operate it according to the instruction manual.

Hitachi provides a panel mount keypad kit (below, right). It includes the mounting flange, gasket, keypad, and other hardware. You can mount the keypad with the potentiometer for a NEMA1 rated installation. The kit also provides for removing the potentiometer knob to meet NEMA 4X requirements, as shown (part no. 4X–KITmini).

Digital Operator Copy Unit - The optional digital operator / copy unit (part no. SRW-0EX) is shown to the right. It has a 2-line display that shows parameters by function code and by name. It has the additional capability of reading (uploading) the parameter settings in the inverter into its memory. Then you can connect the copy unit on another inverter and write (do w nload) the parameter settings into that inverter. OEMs will find this unit particularly useful, as one can use a single copy unit to transfer parameter settings from one inverter to many.

L200 Inverter Specifications

Footnotes for the preceding table and the tables that follow:

Note 1: The protection method conforms to JEM 1030. Note 2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When

using other motors, care must be taken to prevent the rated motor current (50/ 60 Hz) from exceeding the rated output current of the inverter.

Note 3: 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.

Note 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for

the maximum allowable rotation speed.

Note 5: When using the inverter with 3-phase power input, remove the single phase

filter and install a 3-phase filter with the appropriate ratings.

Note 6: For achieving approved input voltage rating categories:

• 460 to 480 VAC – Over-voltage Category 2

• 380 to 460 VAC– Over-voltage Category 3 T o meet the Ov er -v oltage Category 3, insert an EN or IEC standard compliant isolation transformer that is earth grounded and star connected (for Low Voltage Directive).

Note 7: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor. Note 8: The braking torque via capacitive feedback is the av erage deceleration torque

at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking torque. The average deceleration torque varies with motor loss. This v alue decreases when operating be yond 50 Hz. If a large regenerative torque is required, the optional regenerative braking resistor should be used.

Note 9: The frequency command is the maximum frequency at 9.8V for input voltage

0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not satisfactory for your application, contact your Hitachi sales representative.

Note 10: If the inverter is operated outside the region shown in the graph to the right,

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.

Introduction to Variable-Frequency Drives

The Purpose of Motor Speed Control for Industry

Getting Started

What is an Inverter?

Introduction to Variable-Frequency Drives

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:

• Energy savings - HVAC

• Need to coordinate speed with an adjacent process—textiles and printing presses

• Need to control acceleration and deceleration (torque)

• Sensitive loads - elevators, food processing, pharmaceuticals

The term inverter and variable-frequency drive are related and somewhat interchange- able. An electronic motor drive for an AC motor can control the motor’s speed by varying the frequency of the power sent to the motor.

An inverter, in general, is a device that converts DC power to AC power. The figure below shows how the variable-frequency drive employs an internal inverter. The drive first converts incoming AC power to DC through a rectifier bridge, creating an internal DC bus voltage. Then the inv erter circuit conv erts the DC back to AC again to po wer the motor. The special inverter can vary its output frequency and voltage according to the desired motor speed.

Power

Input

L1 L2 L3

The simplified drawing of the inverter shows three double-throw switches. In Hitachi inverters, the switches are actually IGBTs (insulated gate bipolar transistors). Using a commutation algorithm, the microprocessor in the drive switches the IGBTs on and off at a very high speed to create the desired output waveforms. The indu ctance of the motor windings helps smooth out the pulses.

Torque and Constant Volts/Hertz Operation

In the past, AC variable speed drives used an open loop (scalar) technique to control speed. The constant-volts-per-hertz operation maintains a constant ratio between the applied voltage and the applied frequency. With these conditions, AC induction motors inherently delivered constant torque across the operating speed range. For some applications, this scalar technique was adequate.

Today, with the advent of sophisticated microprocessors and digital signal processors (DSPs), it is possible to control the speed and torque of AC induction motors with unprecedented accuracy . The L200 utilizes these de vices to perform complex mathematical calculations required to achieve superior performance. You can choose various torque curves to fit the needs of your application. Constant torque applies the same torque level across the frequency (speed) range. Variable torque, also called reduced torque, lowers the torque delivered at mid-level frequencies. A torque boost setting will add additional torque in the lower half of the frequency range for the constant and variable torque curves. With the free-setting torque curve feature, you can specify a series of data points that will define a custom torque curve to fit your application.

Inverter Input and Three-Phase Power

The Hitachi L200 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. Accordingly, a 200V class inverter requires (nominal) 200 to 240VAC, and a 400V class inverter requires from 380 to 480VAC. Some 200V class inverters will accept single-phase or three-phase power, but all 400V class inverters require a three-phase power supply.

TIP: If your application only has single phase po wer av ailable, refer to L200 in v erters of 3HP or less; they can accept single phase input power.

The common terminology for single phase power is Line (L) and Neutral (N). Threephase power connections are usually labeled Line 1 [R/L1], Line 2 [S/L2] and Line 3 [T/L3]. In any case, the power source should include an earth ground connection. That ground connection will need to connect to the inverter chassis and to the motor frame (see “

Wire the Inverter Output to Motor” on page 2–20).

Page 34

1–14

Introduction to Variable-Frequency Drives

Inverter Output to the Motor

Getting Started

The AC motor must be connected only to the inverter’s output terminals. The output terminals are uniquely labeled (to differentiate them from the input terminals) with the designations U/T1, V/T2, and W/T3. This corresponds to typical motor lead connection designations T1, T2, and T3. It is often not necessary to connect a particular inve rter output to a particular motor lead for a new application. The consequence of swapping any two of the three connections is the rev e rsal of the motor direction. In applications where reversed rotation could cause equipment damage or personnel injury, be sure to verify direction of rotation before attempting full-speed operation. For safety to personnel, you must connect the motor chassis ground to the ground connection at the bottom of the inverter housing.

Notice the three connections to the motor do not include one marked “Neutral” or “Return.” The motor represents a balanced “Y” impedance to the inverter, so there is no need for a separate return. In other words, each of the three “Hot” connections serves also as a return for the other connections, because of their phase relationship.

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. Therefore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop). Also, do not install or use disconnect switches in the wiring from the inverter to the motor (except thermal disconnect). Of course, safety-related devices such as fuses must be in the design to break power during a malfunction, as required by NEC and local codes.

Intelligent Functions and Parameters

Much of this manual is devoted to describing how to use inverter functions and how to configure inverter parameters. The inverter is microprocessor-controlled, and has many independent functions. The microprocessor has an on-board EEPROM for parameter storage. The inverter’s front panel keypad provides access to all functions and parameters, which you can access through other devices as well. The general name for all these devices is the digital operator, or digital operator panel. Chapter 2 will show you how to get a motor running, using a minimal set of function commands or configuring parameters.

The optional read/write programmer will let you read and write inverter EEPROM contents from the programmer. This feature is particularly useful for OEMs who need to duplicate a particular inverter’s settings in many other inverters in assembly-line fashion.

Braking

In general, braking is a force that attempts to slow or stop motor rotation. So it is associated with motor deceleration, but may also occur even when the load attempts to drive the motor faster than the desired speed (overhauling). If you need the motor and load to decelerate quicker than their natural deceleration during coasting, we recommend installing an optional dynamic braking unit. See “

“

Dynamic Braking” on page 5–5 for more information on the BRD–E2 and BRD–EZ2

braking units. The L200 inverter sends excess motor energy into a resistor in the dynamic braking unit to slow the motor and load. For loads that continuously overhaul the motor for extended periods of time, the L200 may not be suitable (contact your Hitachi distributor). For loads that continuously o v erhaul the motor for e xtended periods of time, the L200 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 be a range of practically achievable accelerations and decelerations.

the time required to go from a stop to

maximum frequency (or visa versa). The resulting slope (speed change divided by time) is the acceleration or deceleration. An increase in output frequency uses the acceleration slope, while a decrease uses the deceleration slope. The accel or decel time a particular speed change depends on the starting and

ending frequencies. Howev er, the slope is constant, corresponding to the full-scale accel or decel time setting. For example, the full-scale acceleration setting (time) may be 10 seconds—the time required to go from 0 to 60 Hz.

The L200 inverter can store up to 16 preset speeds. And, it can apply separate acceleration and deceleration transitions from any preset to any other preset speed. A multi-speed profile (shown at right) uses two or more preset speeds, which you can select via intelligent input terminals. This external control can

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 v ary 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.

Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier”

to describe the electronic unit that controls a motor. What does “inverter” mean? A. The terms inverter, drive, and amplifier are used somewhat interchangeably

in industry. Nowadays, the terms drive, variable-frequency drive, variable- speed drive, and inverter are generally used to describe electronic, microprocessor-based motor speed controllers. In the past, variable-speed drive also referred to various mechanical means to vary speed. Amplifier is a term almost exclusively used to describe drives for servo or stepper motors.

Q. Although the L200 inverter is a variable speed drive, can I use it in a fixed-speed

application? A. Yes, sometimes an inverter can be used simply as a “soft-start” device,

providing controlled acceleration and deceleration to a fixed speed. Other functions of the L200 may be useful in such applications, as well. However, using a variable speed drive can benefit many types of industrial and commercial motor applications, by providing controlled acceleration and deceleration, high torque at low speeds, and energy savings over alternative solutions.

Getting Started

Q. Can I use an inverter and AC induction motor in a positioning application?

A. That depends on the required precision, and the slowest speed the motor will

must turn and still deliver torque. The L200 inverter will deliver full torque while turning the motor at only 0.5 Hz (15 RPM). DO NOT use an in verter if you need the motor to stop and hold the load position without the aid of a mechanical brake (use a servo or stepper motion control system).

Q. Can the inverter be controlled and monitored via a network?

A. Yes. L200 inverters ha ve b uilt-in ModBus communications. See Appendix B

for more information on network communications.

Q. Why does the manual or other documentation use terminology such as “200V

class” instead of naming the actual voltage, such as “230 VAC?” A. A specific inverter model is set at the factory to work across a voltage range

particular to the destination country for that model. The model specifications are on the label on the side of the inverter. A European 200V class inverter (“EU” marking) has different parameter settings than a USA 200V class inverter (“US” marking). The initialization procedure (see “

Factory Default Settings” on page 6–8) can set up the inverter for European

or US commercial voltage ranges.

Frequently Asked Questions

Q. Why doesn’t the motor have a neutral connection as a return to the inverter?

A. The motor theoretically represents a “balanced Y” load if all three stator

windings have the same impedance. The Y connection allows each of the three wires to alternately serve as input or return on alternate half-cycles.

Q. Does the motor need a chassis ground connection?

A. Yes, for several reasons. Most importantly, this provides protection in the

event of a short in the motor that puts a hazardous voltage on its housing. Secondly, motors exhibit leakage currents that increase with aging. Lastly, a grounded chassis generally emits less electrical noise than an ungrounded one.

Q. What type of motor is compatible with the Hitachi inverters?

A. Motor type – It must be a three-phase AC induction motor. Use an inverter-

grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class. Motor size – In practice, it’s better to find the right size motor for your application; then look for the inverter to match the motor.

NOTE: There may be other factors that will affect motor selection, including heat dissipation, motor operating speed profile, enclosure type, and cooling method.

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 poles, the slower the top motor speed will be, but it will have higher torque at the base speed.

Q. Will I be able to add dynamic (resistive) braking to my Hitachi L200 driv e after the

initial installation? A. Yes. The L200 inverter already has a dynamic braking circuit built in. Just

add the resistor sized to meet the braking requirements. For more information, contact your nearest Hitachi representative.

Page 39

L200 Inverter

1–19

Q. How will I know if my application will require resistive braking?

A. For new applications, it may be difficult to tell before you actually test a

motor/drive solution. In general, some applications can rely on system losses such as friction to serve as the decelerating force, or otherwise can tolerate a long decel time. These applications will not need dynamic braking. However, applications with a combination of a high-inertia load and a required short decel time will need dynamic braking. This is a physics question that may be answered either empirically or through extensi v e calculations.

Q. 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? A. The purpose of these noise filters is to reduce the inverter electrical noise so

the operation of nearby electrical devices is not affected. Some applications are governed by particular regulatory agencies, and noise suppression is mandatory. In those cases, the inverter must have the corresponding noise filter installed. Other applications may not need noise suppression, unless you notice electrical interference with the operation of other devices.

Getting Started

Q. The L200 features a PID loop feature. PID loops are usually associated with

chemical processes, heating, or process industries in general. How could the PID loop feature be useful in my application?

A. You will need to determine the particular main variable in your application

the motor affects. That is the process variable (PV) for the motor. Over time, a faster motor speed will cause a faster change in the PV than a slow motor speed will. By using the PID loop feature, the inverter commands the motor to run at the optimal speed required to maintain the PV at the desired value for current conditions. Using the PID loop feature will require an additional sensor and other wiring, and is considered an advanced application.

Orientation to Inverter Features

Please take a few moments to unpack your new L200 inverter and perform these steps:

1. Look for any damage that may have occurred during shipping.

2. Verify the contents of the box include: a. One L200 inverter b. One Instruction Manual c. One L200 Quick Reference Guide

3. Inspect the specifications label on the side of the inverter. Make sure it matches the

product part number you ordered.

The L200 Series inve rters vary in size according to the current output rating and motor size for each model number. All feature the same basic keypad and connector interface for consistent ease of use. The inverter construction has a heat sink at the back of the housing. The larger models include a fan(s) to enhance heat sink performance. The mounting holes are predrilled in the heat sink for your convenience. Smaller models have two mounting holes, while larger ones have four. Be sure to use all the mounting holes provided.

Two chassis GND screws are located on the metal tab on the heat sink at the bottom of the inv erter . Ne ver touch the heat sink during or just after operation; it can be very hot.

The electronics housing and front panel are built onto the front of the heat sink.

Inverter Keypad - The inverter uses a digital operator interface, or keypad. The four-digit display can show a variety of performance parameters. LEDs indicate whether the display units are Hertz or Amperes. Other LEDs indicate Power (external), and Run/Stop Mode and Program/Monitor Mode status. Membrane keys Run and Stop/Reset, and an output frequency potentiometer (speed setting knob) control motor operation. The FUNC., , and

keys allow an operator to navigate to the

inverter’s functions and parameter values. The Store key is used when changing a setting.

The SR/SK (Source/Sink) DIP switch configures the inverter’s intelligent inputs for sinking or sourcing type circuit. Note that the installation and Powerup Test steps in this chapter do not require wiring the input terminals. The SR/SK switch configuration is covered in detail in “

Input Terminals” on page 4–9.

The 485/OPE (RS-485/Operator) DIP switch configures the inverter’s RS485 serial port. You can use the inverter’s keypad (OPE-SRmini) either on the inverter, or connected via a cable to the serial port. For the keypad, either position of the 485/OPE DIP switch will work. However, communication with “smart” operator devices requires the proper setting. Using digital operators (such as OPE–SR or OPE–0EX requires the “OPE” setting. Inverter control via a ModBus network communication requires the “485” setting. See “ details.

PRG

Inverter Mounting

and Installation

PRG

The TM/PRG (Terminal/Program) DIP switch affects the inverter’s setting for control sources. Parameter A001 sets the source selection for the inverter’s output frequency (motor speed). Parameter A002 selects the Run command source (for FW and RV). These independently select among sources such as input terminals, inverter keypad keys and potentiometer, internal register settings, ModBus network, etc.

When the TM/PRG switch is set to PRG, parameter settings A001 and A002 are in effect. Howe v e r, when the switch is in the TM (terminal) position, the inverter uses the analog input terminals for the motor speed setting, and uses the [FW] and/or [REV] terminals for the Run command. More information is in “

Control Source Settings” on page 3–10.

Power Wiring Access - First, ensure no power source of any kind is connected to the inverter. If power has been connected, wait five minutes after powerdown and verify the Power LED is OFF to proceed. After removing the front housing cover , the housing partition that covers the power wiring exit will be able to slide upward as shown to the right.

Notice the four wire exit slots (on larger model inv erters) in the housing partition. This helps keep the power wiring (to the left) separate from signal-level logic or analog wiring (to the right).

Remove the housing partition and as shown as set it aside in a secure place while wiring. Never operate the inverter drive with the partition removed or the front housing cover removed.

The power input and motor 3-phase wiring connect to the lower row of terminals. The upper row of power terminals connect to optional dynamic braking components.

The following sections in this chapter will describe the system design and guide you through a step-by-step installation process. After the section on wiring, this chapter will show how to use the front panel keys to access functions and edit parameters.

Basic System Description

A motor control system will obviously include a motor and inverter, as well as a breaker or fuses for safety. If you are connecting a motor to the in verter 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.

Step-by-Step Basic Installation

WARNING: In the cases below involving a general-purpose inverter, a large peak current can flow on the power supply side, sometimes destroying the converter module:

1.The unbalance factor of the power supply is 3% or higher.

2.The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500 kVA or more).

3.Abrupt power supply changes are expected, due to conditions such as: a. Several inverters are interconnected with a short bus. b. A thyristor converter and an inverter are interconnected with a short bus. c. An installed phase advance capacitor opens and closes.

Where these conditions exist or when the connected equipment must be highly reliable, you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current) with respect to the supply voltage on the po wer supply side. Also, where the ef fects of an indirect lightning strike are possible, install a lightning conductor.

This section will guide you through the following basic steps of installation:

Step Activity Page

and Installation

Step 6: In this step, you will connect wiring to the

input of the inverter. First, you must determine whether the inverter model you have requires three-phase power only, or if it can accept either single-phase or three-phase power. All models have the same power connector terminals [R/L1],

[S/L2], and [T/L3]. So, you must refer to the specifications label (on the side of the inverter) for the acceptable power source types! For inverters that can accept single-phase power and are connected that way, terminal [S/L2] will remain unconnected.

The wiring example to the right shows an L200 inverter wired for 3-phase input. Note the use of ring lug connectors for a secure connection.

NOTE: An inverter powered by a portable power generator may receive a distorted power wav eform, o ve rheating the generator. In general, the generator capacity should be five times that of the inverter (kVA).

CAUTION: Be sure that the input voltage matches the inverter specifications:

• Single/Three phase 200 to 240 V 50/60 Hz (up to 2.2kW) for NFEF/NFU models

• Three phase 200 to 240V 50/60Hz (above 2.2kW) for LFU models

• Three phase 380 to 480 V 50/60Hz for HFEF models

CAUTION: Be sure not to power a three-phase-only inverter with single phase power. Otherwise, there is the possibility of damage to the inverter and the danger of fire.

CAUTION: Be sure not to connect an AC power supply to the output terminals. Otherwise, there is the possibility of damage to the inverter and the danger of injury and/or fire.

L200 Inverter

Power Input Output to Motor

CAUTION: Remarks for using ground fault interrupter breakers in the main power supply: Adjustable frequency inv erters with CE-filters (RFI-filter) and shielded (screened) motor cables have a higher leakage current toward Earth GND. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters. Because of the rectifier on the input side of the inv erter there is the possibility to stall the switch-of f function through small amounts of DC current. Please observe the following:

• Use only short time-invariant and pulse current-sensitive ground fault interrupters with higher trigger current.

• Other components should be secured with separate ground fault interrupters.

• Ground fault interrupters in the power input wiring of an inverter are not an absolute protection against electric shock.

and Installation

CAUTION: Be sure to install a fuse in each phase of the main power supply to the inverter. Otherwise, there is the danger of fire.

Step-by-Step Basic Installation

Wire the Inverter Output to Motor

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. If the motor does not have three power input leads, stop the installation and verify the motor type. Other guidelines for wiring the motor include:

• Use an inverter-grade motor for maximum motor life (1600V insulation).

• For standard motors, use the AC reactor accessory if the wiring between the inverter and motor exceeds 10 meters in length.

and Installation

Inverter Mounting

Simply connect the motor to the terminals [U/T1], [V/T2], and [W/T3] as shown to the right. This is a good time to connect the chassis ground lug on the drive as well. The motor chassis ground must also connect to the same point. Use a star ground (singlepoint) arrangement, and never daisy-chain the grounds (point-to-point).

Use the same wire gauge on the motor and chassis ground wiring as you used on the power input wiring in the previous step. After completing the wiring:

• Check the mechanical integrity of each wire crimp and terminal connection.

• Replace the housing partition that covers access to the power connections.

• Replace the front housing cover. First, align the two hinging tabs. Then press the cover onto the inverter until the locking tabs click into place.

Step 8: After mounting and wiring the inverter,

remove any covers from the inverter housing. This includes material over the side ventilation ports.

WARNING: Make sure the input power to the inverter is OFF. If the drive has been powered, leave it OFF for five minutes before continuing.

Powerup Test

Step 9: After wiring the inverter and motor, you’re ready to do a powerup test. The

procedure that follows is designed for the first-time use of the drive. Please verify the following conditions before conducting the powerup test:

• You have followed all the steps in this chapter up to this step.

• The inverter is new, and is securely mounted to a non-flammable vertical surface

• The inverter is connected to a power source and motor.

and Installation

• No additional wiring of inverter connectors or terminals has been done.

• The power supply is reliable, and the motor is a known working unit, and the motor nameplate ratings match the inverter ratings.

• The motor is securely mounted, and is not connected to any load.

Goals for the Powerup Test

If there are any exceptions to the above conditions at this step, please take a moment to take any measures necessary to reach this basic starting point. The specific goals of this powerup test are:

1. Verify that the wiring to the power supply and motor is correct.

2. Demonstrate that the inverter and motor are generally compatible.

3. Get an 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.

Pre-test and Operational Precautions

and Installation

Inverter Mounting

Powerup Test

The following instructions apply to the powerup test, or to any time the inverter is powered and operating. Please study the following instructions and messages before proceeding with the powerup test.

1. The power supply must have fusing suitable for the load. Check the fuse size chart

presented in Step 5, if necessary.

2. Be sure you have access to a disconnect switch for the drive input power if necessary.

However, do not turn OFF power during inverter operation unless it is an emergency.

3. Turn the keypad potentiometer to the minimum position (fully counter-clockwise). CAUTION: The heat sink fins will have a high temperature. Be careful not to touch

them. Otherwise, there is the danger of getting burned.

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. Otherwise, there is the danger of equipment damage and/or injury.

CAUTION: Check the following before and during the powerup test. Otherwise, there is the danger of equipment damage.

• Is the shorting bar between the [+1] and [+] terminals installed? DO NOT power or operate the inverter if the jumper is removed.

• Is the direction of the motor rotation correct?

• Did the inverter trip during acceleration or deceleration?

• Were the rpm and frequency meter readings as expected?

• Were there any abnormal motor vibrations or noise?

Powering the Inverter

If you have followed all the steps, cautions and warnings up to this point, you’re ready to apply power. After doing so, the following events should occur:

• The POWER LED will illuminate.

• The numeric (7-segment) LEDs will display a test pattern, then stop at 0.0.

• The Hz LED will be ON.

If the motor starts running unexpectedly or any other problem occurs, press the STOP key. Only if necessary should you remove power to the inverter as a remedy.

NOTE: If the inverter has been previously powered and programmed, the LEDs (other than the POWER LED) may illuminate differently than as indicated abo ve. If necessary, you can initialize all parameters to the factory default settings. See “

Default Settings” on page 6–8.

After using the keypad for parameter editing, it’s a good idea to switch the inverter from Program Mode to Monitor Mode. The PRG LED will be OFF, and the Hertz or Ampere LED indicates the display units.

For the powerup test, monitor the motor speed indirectly by viewing the inverter’s output frequency. The output frequency must not be confused with base frequency (50/ 60 Hz) of the motor, or the carrier frequency (switching frequency of the inverter, in the kHz range). The monitoring functions are in the “D” list, located near the top left of the

Powerup Test Observations and Summary

Step 10: Reading this section will help you make some useful observations when first

running the motor.

and Installation

Inverter Mounting

Error Codes - If the inverter displays an error code (format is “E X X”), see “

Monitoring

Trip Events, History, & Conditions” on page 6–5 to interpret and clear the error.

Acceleration and Deceleration - The L200 inverter has programmable acceleration and deceleration values. The test procedure left these at the default value, 10 seconds. You can observe this by setting the potentiometer at about half speed before running the motor . Then press R UN, and the motor will take 5 seconds to reach a steady speed. Press the STOP key to see a 5 second deceleration to a stop.

State of Inverter at Stop - If you adjust the motor’ s speed to zero, the motor will slow to a near stop, and the inverter turns the outputs OFF. The high-performance L200 can rotate at a very slow speed with high torque output, but not zero (must use serv o systems with position feedback for that feature). This characteristic means you must use a mechanical brake for some applications.

Interpreting the Display - First, refer to the output frequency display readout. The maximum frequency setting (parameter A004) defaults to 50 Hz or 60 Hz (Europe and United States, respectively) for your application.

Example: Suppose a 4-pole motor is rated for 60 Hz operation, so the inverter is configured to output 60 Hz at full scale. Use the following formula to calculate the RPM.

Speed in RPM

Frequency 60×

----------------------------------------

Pairs of poles

Frequency 120×

-------------------------------------------

# of poles

60 120×

--------------------- 1800RPM== ==

The theoretical speed for the motor is 1800 RPM (speed of torque vector rotation). However, the motor cannot generate torque unless its shaft turns at a slightly different speed. This difference is called slip. So it’s common to see a rated speed of approxi- mately 1750 RPM on a 60 Hz, 4-pole motor. Using a tachometer to measure shaft speed, you can see the difference between the inverter output frequency and the actual motor speed. The slip increases slightly as the motor’s load increases. This is why the inverter output value is called “frequency,” since it is not exactly equal to motor speed. You can program the inv erter to display output frequency in units more directly related to the load speed by entering a constant (discussed more in depth on page 3–38

Run/Stop Versus Monitor/Program Modes – The Run LED on the inverter is ON in Run Mode, and OFF in Stop Mode. The Program LED is ON

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. This arrangement lets you program some values while the inverter is operating— providing flexibility for maintenance personnel.

Introduction

Hitachi variable frequency drives (inverters) use the latest electronics 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 component. And this can make a product seem diff icult to use, b ut th e goal of this chapter is to make this easier for you.

As the powerup test in Chapter 2 demonstrated, you do not have to program very many parameters to run the motor. In fa ct, most applications would benef it only from programming just a few, specific parameters. This chapter will explain the purpose of each set of parameters, and help you choose the ones that are important to your application.

If you are developing a new application for the inverter and a motor, finding the right parameters to change is mostly an exercise in optimization. Therefore, it is okay to begin running the motor with a loosely tuned system. By making specific, individual changes and observing their effects, you can achieve a finely tuned system.

Introduction to Inverter Programming

The front panel keypad is the first and best way to get to kno w the inverter’s capabilities. Every function or programmable parameter is accessible from the keypad. The other devices simply imitate the keypad’s layout and inverter access, while adding another valuable aspect to the system. For example, the Digital Operator/Copy Unit can transfer one inverter’s parameter settings to another inverter, while still providing standard operator keypad control. In this way, you can use a variety of programming de vices with

NOTE: When an external digital operator device such as an OPE–SRmini or

Operational Modes

The RUN and PRG 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 shutting down the machine.

The occurrence of a fault during operation will cause the inverter to enter the T r ip Mode as sho wn. 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

Run Mode Edits

The inverter can be in Run Mode (inverter output is controlling motor) and still allow you to edit certain parameters. This is useful in applications that must run continuously, yet need some inverter parameter adjustment.

The parameter tables in this chapter 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. The Software Lock Setting (parameter B031) determines when the Run Mode access permission is in effect and access permission in other conditions, 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 3–35 for more information.

Control Algorithms

The motor control program in the L200 inverter has tw o sinusoidal PWM switching algorithms. The intent is that you select the best algorithm for the motor characteristics in your application. Both algorithms generate 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 3–17). Therefore, choose the best

algorithm early in your application design process.

You can access important system parameter values with the “D” Group monitoring functions, whether the inverter is in Run Mode or Stop Mode. After selecting the function code number for the parameter you want to monitor, press the Function key once to show the value on the display. In functions D005 and D006, the intelligent terminals use individual segments of the display to show ON/OFF status.

If the inverter display is set to monitor a parameter and powerdown occurs, the inverter stores the present monitor function setting. For your convenience, the display automatically returns to the previously monitored parameter upon the next powerup.

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.

The base frequency and maximum frequency settings interact according to the graph below (left). The in v erter output operation follows the constant V/f curve until it reaches the full-scale output voltage at the base frequency. This initial straight line is the constant-torque part of the operating characteristic. The horizontal line over to the maximum frequency serves to let the motor run faster , b ut at a reduced torque. This is the constant-power operating range. If you want the motor to output constant torque ov er its entire operating range (limited to the motor nameplate voltage and frequency rating), then set the base frequency and maximum frequency equal as shown (below right).

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 –10V) 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. The analog input settings adjust the curve characteristics between the analog input and the frequency output.

Adjusting [O–L] characteristics – In the graph to the right, A013 and A014 select the active portion of the input voltage range. Parameters A011 and A012 select the start and end frequency of the converted output frequency range, respectively. Together, these four parameters define the major line segment as shown. When the line does not begin at the origin (A011 and A013 > 0), then A015 defines whether the inverter outputs 0Hz or the A011-specified frequency when the analog input value is less than the A013 setting. When the input voltage is greater than the A014 ending value, the inverter outputs the ending frequency specified by A012.

Multi-speed and Jog Frequency Setting

The L200 inverter has the capability to store and output up to 16 preset frequencies to the motor (A020 to A035). As in traditional motion terminology, we call this multi-speed profile capability. These preset frequencies are selected by means of digital inputs to the inverter. The inverter applies the current acceleration or deceleration setting to change from the current output frequency to the new one. The first multi-speed setting is duplicated for the second motor settings (the remaining 15 multi-speeds apply only to the first motor).

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.

• A scale factor in A075 lets you multiply the PV by a factor, converting it into engineering units for the process.

• Proportional, integral, and derivative gains are all adjustable.

Second Acceleration and Deceleration Functions

The L200 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). Or, you can use intelligent input [2CH] to trigger this transition. These profile options are also available for the second motor settings. Select a transition method via A094 as depicted below. Be careful not to confuse the second acceleration/deceleration settings with settings for the second motor!
