Page 33 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 34 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 37: Frequently Asked Questions
1–17 L200 Inverter 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 38 The greater the number of poles, the slower the top motor speed will be, but it will have higher torque at the base speed. Will I be able to add dynamic (resistive) braking to my Hitachi L200 drive after the initial installation? Yes.
Page 39 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 85 3–13 L200 Inverter 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 develop- ment you may prefer using the potentiometer, but you may switch to an external source (control terminal setting) in the finished application, for example.
Page 86 3–14 “A” Group: Standard Functions 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.

Page 93 3–21 L200 Inverter Frequency-related Functions Frequency Limits – Upper and lower Output limits can be imposed on the inverter frequency output frequency. These limits will apply Upper regardless of the source of the speed refer- A061 limit ence. You can configure the lower frequency limit to be greater than zero as Settable shown in the graph.
Page 94 3–22 “A” Group: Standard Functions 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 95: Pid Control
3–23 L200 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 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 96 3–24 “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 is subject to input voltage fluctuations. However, the inverter cannot boost its motor output to a voltage higher than the power input voltage.

Page 137: Using Intelligent Input Terminals
4–9 L200 Inverter Using Intelligent Input Terminals 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 138 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 139 4–11 L200 Inverter The two diagrams below show input wiring circuits using an external supply. If using the upper wiring diagram, be sure to use a diode with the external supply. This will prevent a power supply contention in case the SR/SK switch is accidentally placed in the incorrect position.
Page 140 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 145 4–17 L200 Inverter Set Second Motor If you assign the [SET] function to an intelligent input terminal, you can select between two sets of motor parameters. The second parameters store an alternate set of motor characteristics. When the terminal [SET] is turned ON, the inverter will use the second set of parameters to generate the frequency output to the motor.
Page 146 4–18 Using Intelligent Input Terminals Two-stage Acceleration and Deceleration When terminal [2CH] is turned ON, the Output target inverter changes the rate of acceleration and frequency frequency deceleration from the initial settings (F002 second and F003) to use the second set of accelera- initial tion/deceleration values.
Page 147 4–19 L200 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 148: External Trip
4–20 Using Intelligent Input Terminals External Trip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output. This is a general purpose interrupt type feature, and the meaning of the error depends on what you connect to the [EXT] terminal. Even if the [EXT] input is turned OFF, the inverter remains in the trip state.
Page 149: Unattended Start Protection
4–21 L200 Inverter Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.
Page 150: Software Lock
4–22 Using Intelligent Input Terminals Software Lock When the terminal [SFT] is turned ON, the data of all the parameters and functions (except the output frequency, depending on the setting of B031) is locked (prohibited from editing). When the data is locked, the keypad keys cannot edit inverter parameters. To edit parameters again, turn OFF the [SFT] terminal input.
Page 151 4–23 L200 Inverter Analog Input Current/Voltage Select The [AT] terminal selects whether the inverter uses the voltage [O] or current [OI] input terminals for external frequency control. When intelligent input [AT] is ON, you can set the output frequency by applying a current input signal at [OI]-[L]. When the [AT] input is OFF, you can apply a voltage input signal at [O]-[L] to set the output frequency.
Page 152: Reset Inverter

Page 153 4–25 L200 Inverter 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 resistance. When the resistance value of the thermistor connected to terminal [TH] (6) and [L] is more than 3 k Ω ±10%, the inverter enters the Trip Mode, turns OFF the output to the motor, and indicates the trip status E35.
Page 154 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 155 4–27 L200 Inverter The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensi- tive input; an OFF-to-ON transition gives the Start command. The control of direction is level-sensitive, and the direction may be changed at any time. STP (Stop Motor) is also a level-sensitive input.
Page 156 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.
Page 157 4–29 L200 Inverter Remote Control Up and Down Functions The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time of this function is same as normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate according to these principles: •...
Page 158 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 159 4–31 L200 Inverter Force Operation from Digital Operator This function permits a digital operator interface to override the following two settings in the inverter: • A001 - Frequency source setting • A002 - Run command source setting When using the [OPE] terminal input, typically A001 and A002 are configured for sources other than the digital operator interface for the output frequency and Run command sources, respectively.
Page 160: 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 163 4–35 L200 Inverter Internal Relay Output The inverter has an internal relay output with Inverter logic normally open and normally closed contacts (Type circuit board 1 form C). The output signal that controls the relay is configurable; the Alarm Signal is the default setting.
Page 164 4–36 Using Intelligent Output Terminals 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 165: Run Signal
4–37 L200 Inverter Run Signal When the [RUN] signal is selected as an [FW], intelligent output terminal, the inverter [RV] outputs a signal on that terminal when it is in Run Mode. The output logic is active low, and B082 is the open collector type (switch to ground).
Page 166 4–38 Using Intelligent Output Terminals Frequency Arrival Signals The Frequency Arrival group of outputs help coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
Page 167 4–39 L200 Inverter Frequency arrival output [FA1] uses the Output standard output frequency (parameter 1.5 Hz freq. F001) as the threshold for switching.

Page 170: Alarm Signal
4–42 Using Intelligent Output Terminals Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the STOP RESET Stop diagram at right). When the fault is cleared the alarm signal becomes inactive.
Page 171 4–43 L200 Inverter The alarm relay output can be configured in two main ways: • Trip/Power Loss Alarm – The alarm relay is configured as normally closed (C036=1) by default, shown below (left). An external alarm circuit that detects broken wiring also as an alarm connects to [AL0] and [AL1].
Page 172: Analog Input Disconnect Detect
4–44 Using Intelligent Output Terminals Analog Input Disconnect Detect This feature is useful when the inverter receives a speed reference from an external device. Upon input signal loss at either the [O] or [OI] terminal, the inverter normally just decelerates the motor to a stop. However, the inverter can use the intelligent output terminal [Dc] to signal other machinery that a signal loss has occurred.
Page 173: Pid Second Stage Output
4–45 L200 Inverter PID Second Stage Output The inverter has a built-in PID loop feature for two-stage control, useful for certain applications such as building ventilation or heating and cooling (HVAC). In an ideal control environment, a single PID loop controller (stage) would be adequate. However, in certain conditions, the maximum output energy from the first stage is not enough to maintain the Process Variable (PV) at or near the Setpoint (SP).
Page 174 4–46 Using Intelligent Output Terminals To use the PID Second Stage Output feature, you will need to choose upper and lower limits for the PV, via C053 and C052 respectively. As the timing diagram below shows, these are the thresholds Stage #1 inverter uses to turn ON or OFF Stage #2 inverter via the [FBV] output.

To enable PID operation, set A071 = 01.
