Page 38: 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. Many applications benefit from a motor with variable speed, in several ways: •...
Page 39 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.
Page 40 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).
Page 41 For loads that continuously overhaul the motor for extended periods of time, the L200 Hitachi distributor). For loads that continuously overhaul the motor for extended periods of time, the L200 may not be suitable (contact your Hitachi distributor).
Page 42 1–22 Introduction to Variable-Frequency Drives Velocity Profiles The L200 inverter is capable of sophisticated speed control. A graphical representation of that capability will help you understand and configure the associated parameters. This manual makes use of the velocity profile graph used in industry (shown at right). In the example, acceleration is a ramp to a set speed, and deceleration is a decline to a stop.
Page 43: Frequently Asked Questions
Frequently Asked Questions What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? 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 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.
Page 45 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.

Page 99 Be aware that running the motor at a low speed for a long time can cause motor overheating. This is particularly true when manual torque boost is ON, or if the motor relies on a built-in fan for cooling. NOTE: Manual torque boost applies only to constant torque (A044=00) and variable torque (A044=01) V/f control.

Page 101 DC Braking Settings The DC braking feature can provide additional stopping torque when compared to a normal deceleration to a stop. DC braking is particularly useful at low speeds when normal decelera- tion torque is minimal. When you enable DC braking, the inverter injects a DC voltage into the motor windings during deceleration below a frequency you can specify (A052).
Page 102 3–22 “A” Group: Standard Functions Frequency-related Functions Frequency Limits – Upper and lower limits can be imposed on the inverter output frequency. These limits will apply regardless of the source of the speed refer- ence. You can configure the lower frequency limit to be greater than zero as shown in the graph.
Page 103 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.
Page 104: Pid Control
3–24 “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.
Page 105 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 106 3–26 “A” Group: Standard Functions Second Acceleration and Deceleration Functions The L200 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape.

This profile is useful for favoring the load characteristics in particu- lar applications. Curve settings for acceleration and decel- eration are independently selected.
Page 109 Additional Analog Input Settings Input Range Settings – The parameters in the following table adjust the input charac- teristics of the analog current input. 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.
Page 110 3–30 “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).
Page 111 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).

Page 115 Electronic Thermal Overload Alarm Setting The thermal overload detection protects the inverter and motor from overheating due to an excessive load. It uses a current/inverse time curve to determine the trip point. First, use B013 to select the torque charac- teristic that matches your load.
Page 116 3–36 “B” Group: Fine Tuning Functions Note 1: For inverter models 005NFE(F), 011NFE(F), and 030HFE(F), the overload- related parameter settings are different from the rated amperes. Therefore, be sure to set the electronic thermal overload according to the actual motor driven by the particular inverter.

Page 123 In most applications a controlled deceleration is desirable, corresponding to B091=00. However, applications such as HVAC fan control will often use a free-run stop (B091=01). This practice decreases dynamic stress on system components, prolonging system life. In this case, you will typically set B088=01 in order to resume from the current speed after a free-run stop (see diagram below, right).

Page 125 The graph below shows an inverter output profile that starts decelerating to a stop. At two different points during the deceleration, regenerative voltage elevates the DC bus level, exceeding the LADSTOP threshold set by B131. When the Over-voltage LADSTOP feature is enabled by B130 = 01, the inverter stops the deceleration ramp in each case until the DC bus level is again less than the threshold value.

Page 147 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.
Page 148: 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.

Terminals [1], [2], [3], [4], and [5] 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 154 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.
Page 155 This will prevent a power supply contention in case the SR/SK switch is accidentally placed in the incorrect position. Be sure to use the correct SR/SK switch position shown for each wiring diagram.
Page 156 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).
Page 157 Multi-Speed Select The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condition. These speeds are acces- sible through programming four of the intelligent terminals as binary-encoded inputs CF1 to CF4 per the table to the right.

Page 159 Jogging Command The Jog input [JG] is used to command the motor to rotate slowly in small increments for manual operation. The speed is limited to 10 Hz. The frequency for the jogging opera- tion is set by parameter A038. Jogging does not use an acceleration ramp, so we recom- mend setting the jogging frequency A038 to 5 Hz or less to prevent tripping.

Page 163 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 164: External Trip

Page 170 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.
Page 171 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.
Page 172 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.

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: •...
Page 174 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.
Page 175 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.
Page 176: Add Frequency Enable
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.
Page 177: Force Terminal Mode

Page 178 4–34 Using Intelligent Input Terminals Quick Start Enable When the [RDY] input is ON, the inverter is always in Run Mode, even when the motor rotation has stopped. The pupose of the quick start feature is to improve (decrease) the startup time of the motor in response to a Run Command.
Page 179: 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 –...
Page 180 4–36 Using Intelligent Output Terminals Internal Relay Output The inverter has an internal relay output with normally open and normally closed contacts (Type 1 form C). The output signal that controls the relay is configurable; the Alarm Signal is the default setting.
Page 181 Output Signal ON/OFF Delay Function Intelligent outputs including terminals [11], [12], 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.
Page 182: Run Signal

The output logic is active low, and is the open collector type (switch to ground). Option Terminal Function Name...
Page 183 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.
Page 184 4–40 Using Intelligent Output Terminals Frequency arrival output [FA1] uses the standard output frequency (parameter F001) as the threshold for switching. In the figure to the right, Frequency Arrival [FA1] turns ON when the output frequency gets within 0.5 Hz below or 1.5 Hz above the target constant frequency.
Page 185: Overload Advance Notice Signal
Overload Advance Notice Signal When the output current exceeds a preset value, the [OL] terminal signal turns ON. The parameter C041 sets the overload threshold. The overload detection circuit operates during powered motor opera- tion and during regenerative braking. The output circuits use open-collector transistors, and are active low.
Page 186: Output Deviation For Pid Control
4–42 Using Intelligent Output Terminals Output Deviation for PID Control The PID loop error is defined as the magnitude (absolute value) of the differ- ence between the Setpoint (target value) and the Process Variable (actual value). When the error magnitude exceeds the preset value for C044, the [OD] terminal signal turns ON.
Page 187: Alarm Signal
Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactive. We must make a distinction between the alarm signal AL and the alarm relay contacts [AL0], [AL1] and [AL2].
Page 188 4–44 Using Intelligent Output Terminals 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].
Page 189: Analog Input Disconnect Detect
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.
Page 190: Pid Second Stage Output
4–46 Using Intelligent Output Terminals 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).
Page 191 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.

The PV high limit and PV low limit param- eters, C052 and C053, do not function as process alarm thresholds.
Page 193 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.

Page 197: Analog Input Operation
Analog Input Operation The L200 inverters provide for analog input to command the inverter frequency output value. The analog input terminal group includes the [L], [OI], [O], and [H] terminals on the control connector, which provide for Voltage [O] or Current [OI] input. All analog input signals must use the analog ground [L].
Page 198 4–54 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).
Page 199: Analog Output Operation
Analog Output Operation In inverter applications it is useful to monitor the inverter operation from a remote location or from the front panel of an inverter enclosure. In some cases, this requires only a panel-mounted volt meter. In other cases, a controller such as a PLC may provide the inverter’s frequency command, and require inverter feedback data (such as output frequency or output current) to...
Page 200: Pid Loop Operation
4–56 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.
Page 201 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.
Page 202: Configuring The Inverter For Multiple Motors
4–58 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 have approximately the same speed.
Page 203 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.

Please read the following safety messages before troubleshooting or performing mainte- nance on the inverter and motor system. WARNING: Wait at least five (5) minutes after turning OFF the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock.
Page 215: Troubleshooting Tips
A002 is correct. • Check terminals [L1], [L2], and [L3/N], then [U/T1], [V/T2], and [W/T3]. • Turn ON the power supply or check fuses. • Press the Func. key and determine the error type. Eliminate the error cause, then clear the error (Reset).
Page 216 • Check frequency upper limit setting (A061) • Increase the motor capacity (both inverter and motor). • Fix power supply problem. • Change the output frequency slightly, or use the jump frequency setting to skip the problem frequency. • Verify the V/f settings match motor specifications.
Page 217: Monitoring Trip Events, History, & Conditions
Monitoring Trip Events, History, & Conditions Fault Detection and Clearing The microprocessor in the inverter detects a variety of fault conditions and captures the event, record- ing it in a history table. The inverter output turns OFF, or “trips” similar to the way a circuit breaker trips due to an over-current condition.

Page 219 Trip History and Inverter Status We recommend that you first find the cause of the fault before clearing it. When a fault occurs, the inverter stores important performance data at the moment of the fault. To access the data, use the monitor functions (Dxxx) and select D081 for details about the present fault (E ).

D–2 CE–EMC Installation Guidelines CE–EMC Installation Guidelines You are required to satisfy the EMC directive (89/336/EEC) when using an L200 inverter in an EU country. To satisfy the EMC directive and to comply with standard, follow the guidelines in this section. 1.
Page 295 4. Take measures to minimize interference that is frequently coupled in through installa- tion cables. • Separate interfering cables with 0.25m minimum from cables susceptible to inter- ference. A particularly critical point is laying parallel cables over longer distances. If two cables intersect (one crosses over the other), the interference is smallest if they intersect at an angle of 90°.
Page 296 D–4 CE–EMC Installation Guidelines Some L200 inverters designed for use in Europe (–xxxLFEF/xxxHFEF models) have built-in line filters. Inverter models –xxxLFE/xxxHFE do not have built-in line filters. In the event your application needs additional filtering, the following diagrams show control panel mounting and wiring examples for different filter types.
