Storage temperature refers to the temperature in transportation. Conforms to the test method specified in JIS C0040(1999). When using the inverter from 40º to 50ºC ambient, the output current of the inverter must be derated (see the next section on derating curves).

OPERATION and PROGRAMMING

L300P Series can be easily operated with the digital operator (OPE-SR) provided as standard. The Digital operator can also be detached and used for remote-control. A multilingual (English, French, German Italian, Spanish, and Portuguese) operator with copy function (SRW-0EX) or a digital operator without potentiometer(OPE-S) is also available as an option. (For US version, OPE-SRE (English overlay with potentiometer) is provided as standard.)

Explanation of Terminals

Common terminal for H, O, O2, OI, AM, and AMI. Do not ground.

Power supply for frequency command input

Maximum frequency is attained at DC 10V in DC 0-10V range. Set the voltage at A014 to command maximum frequency below DC 10V.

O2 signal is added to the frequency command of O or OI in DC

-

0

±10V range. By changing configuration, frequency command

can be input also at O2 terminal.

Maximum frequency is attained at DC 20mA in DC 4-20mA range. When the intelligent terminal configured as AT is on, OI signal is enabled.

Selection of one function from: Output frequency, output current, torque, output voltage, input power, electronic thermal load ratio, and LAD frequency.

The inverter trips when the external thermistor detects abnormal temperature. Common terminal is CM1. [Recommended thermistor characteristics] Allowable rated power: 100mW or over. Impedance in the case of abnormal temperature: 3k Note: Thermal protection level can be set between 0 and 9999 .

[DC0-10V output (PWM output)] Selection of one function from: Output frequency, output current, torque, output voltage, input power, electronic thermal load ratio, and LAD frequency. [Digital pulse output (Pulse voltage DC 0/10V)] Outputs the value of output frequency as digital pulse (duty 50%)

Internal power supply for input terminals. In the case of source type logic, common terminal for contact input terminals.

Common terminal for P24, TH, and FM. In the case of sink type logic, common terminal for contact input terminals. Do not ground.

The motor runs forward when FW terminal is ON, and stops when FW is OFF.

Assign 5 functions to terminals. (Refer to the standard specifications for the functions.)

Select sink or source logic with the short-circuit bar on the control terminals. Sink logic: Short P24 to PLC / Source logic: Short CM1 to PLC. When applying external power source, remove the short-circuit bar and connect PLC terminal to the external device.

Assign 3 functions to two NO contacts and one NO-NC contact. (Refer to the standard specifications for the functions.)

Out of operation due to under-voltage

An error has been detected in an expantion card or at its connecting terminals.

One of three lines of 3-phase power supply is missing.

While at constant speed During deceleration During acceleration Others

(*1)

You can clear the error by pressing the Start / Reset key 10 seconds after the trip occurred.

(*2)

If an EEPROM error occurs, be sure to confirm the parameter data values are still correct.

When the built-in EEPROM memory has problems due to noise or excessive temperature, the inverter trips and turns off its output.

When a malfunction in the built-in CPU has occurred, the inverter trips and turns off its output.

When a signal to an intelligent input terminal configured as EXT has occurred, the inverter trips and turns off its output.

The inverter is protected by the detection of ground faults between the inverter output and the motor during power-up tests. This feature protects the inverter only.

When the input voltage is higher than the specified value, it is detected 60 seconds after power-up and the inverter trips and turns of its output.

When instantaneous over-current has occurred, the inverter trips and turns off its output to protect main circuit element.

When the thermistor inside the motor detects temperature higher than the specified value, the inverter trips and turns off its output.

When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor, the inverter trips and turns off its output.

When a motor overload is detected by the electronic thermal function, the inverter trips and turns off its output.

The inverter output was short-circuited, or the motor shaft is locked or has a heavy load. These conditions cause excessive current for the inverter, so the inverter output is turned off.

When the regenerative braking resistor exceeds the usage time allowance or an over-voltage caused by the stop of the BRD function is detected, the inverter trips and turns off its output.

A decrease of internal DC bus voltage below a threshold results in a control circuit fault. This condition can also generate excessive motor heat or cause low torque. The inverter trips and turns off its output.

If a strong source of electrical interference is close to the inverter or abnormal operations occur in the builtin CT(Current transformer), the inverter trips and turns off its output.

An error occurs when power is cycled while the inverter is in RUN mode if the Unattended Start Protection (USP) is enabled. The inverter trips and does not go into RUN mode until the error is cleared.

When power is cut for more than 15msec., the inverter trips and turns off its output. If power failure continues, the error will be cleared. The inverter restarts if it is in RUN mode when power is cycled.

When the inverter internal temperature is higher than the specified value, the thermal sensor in the inverter module detects the higher temperature of the power devices and trips, turning off the inverter output.

Gate array error

Communication error has occured between CPU and gate array.

Due to insufficient voltage, the inverter has turned off its output and been trying to restart. If it fails to restart, it goes into the under-voltage error.

This is useful in suppressing harmonics induced on the power supply lines, or when the main power voltage imbalance exceeds 3% (and power source capacity is more than 500kVA), or to smooth out line fluctuations. It also improves the power factor.

This filter reduces the conducted noise in the power supply wiring between the inverter and the power distribution system. Connect it to the inverter primary (input side).

Electrical noise interference may occur on nearby equipment such as a radio receiver. This magnetic choke filter helps reduce radiated noise (can also be used on output).

This capacitive filter reduces radiated noise from the main power wires in the

inverter input side. The choke suppresses harmonics generated by the inverter. However, it will not protect the input diode bridge rectifier.

Braking components are useful for increasing the inverter's control torque for high

duty-cycle (on-off) applications, and improving the decelerating capability.

Electrical noise interference may occur on nearby equipment such as a radio

receiver. This magnetic choke filter helps reduce radiated noise (can also be

used on input).

Reduces radiated noise from wiring in the inverter output side.

This reactor reduces the vibration in the motor caused by the inver-

ter's switching waveforms, by smoothing the waveforms to approxi-

mate commercial power quality. It is also useful when wiring from the inverter to

the motor is more than 10m in length, to reduce harmonics.

FOR CORRECT OPERATION

The overspeed endurance of a general-purpose motor is 120% of the rated speed for 2 minutes (JIS C4,004). For operation at higher than 60Hz, it is required to examine the allowable torque of the motor, useful life of bearings, noise, vibration, etc. In this case, be sure to consult the motor manufacturer as the maximum allowable rpm differs depending on the motor capacity, etc.

The torque characteristics of driving a general-purpose motor with an inverter differ from those of driving it using commercial power (starting torque decreases in particular). Carefully check the load torque characteristic of a connected machine and the driving torque characteristic of the motor.

An inverter-driven general-purpose motor heats up quickly at lower speeds. Consequently, the continuous torque level(output) will decrease at lower motor speeds. Carefully check the torque characteristics vs speed range requirements.

When run by an inverter, a general-purpose motor generates noise slightly greater than with commercial power. When run by an inverter at variable speeds, the motor may generate vibration, especially because of (a) unbalance of the

rotor including a connected machine, or (b) resonance caused by the natural vibration frequency of a mechanical system. Particularly, be careful of (b) when operating at variable speeds a machine previously fitted with a constant speed motor. Vibration can be minimized by (1) avoiding resonance points using the frequency jump function of the inverter, (2) using a tire-shaped coupling, or (3) placing a rubber shock absorber beneath the motor base.

Under continued, low-speed operation, oil lubrication can deteriorate in a power transmission mechanism with an oil-type gear box (gear motor) or reducer. Check with the motor manufacturer for the permissible range of continuous speed. To operate at more than 60 Hz, confirm the machine’s ability to withstand the centrifugal force generated.

Power transmission mechanism

The allowable rotation range of continuous drive varies depending on the lubrication method or motor manufacturer. (Particularly in case of oil lubrication, pay attention to the low frequency range.)

For use of a brake-equipped motor, be sure to connect the braking power supply from the primary side of the inverter. There are different kinds of pole-change motors (constant output characteristic type, constant torque characteristic type, etc.),

with different rated current values. In motor selection, check the maximum allowable current for each motor of a different pole count. At the time of pole changing, be sure to stop the motor.

The rated current of a submersible motor is significantly larger than that of the general-purpose motor. In inverter selection, be sure to check the rated current of the motor. Also see: Application to the 400V-class motor.

Inverter drive is not suitable for a safety-enhanced explosion-proof type motor. The inverter should be used in combination with a pressure-proof explosion-proof type motor. *Explosion-proof verification is not available for L300P Series. For explosion-proof operation, use other series of motors.

In most cases, the synchronous (MS) motor and the high-speed (HFM) motor are designed and manufactured to meet the specifications suitable for a connected machine. As to proper inverter selection, consult the manufacturer.

Application to Motors

[Application to general-purpose motors]

Run or stop of the inverter must be done with the keys on the operator panel or through the control circuit terminals. Do not operate by installing a electromagnetic contactor (Mg) in the main circuit.

When the protective function is operating or the power supply stops, the motor enters the free run stop state. When an emergency stop is required or when the motor should be kept stopped, use of a mechanical brake should be considered.

A max. 400Hz can be selected on the L300P Series. However, a two-pole motor can attain up to approx. 24,000 rpm, which is extremely dangerous. Therefore, carefully make selection and settings by checking the mechanical strength of the motor and connected machines. Consult the motor manufacturer when it is necessary to drive a standard (general-purpose) motor above 60 Hz.

Notes on Use

[Drive]

[Application to special motors]

[Application to the 400V-class motor]

A system applying a voltage-type PWM inverter with IGBT may have surge voltage at the motor terminals resulting from the cable constants including the cable length and the cable laying method. Depending on the surge current magnification, the motor coil insulation may be degraded. In particular, when a 400V-class motor is used, a longer cable is used, and critical loss can occur, take the following countermeasures: (1) install the LCR filter between the inverter and the motor, (2) install the AC reactor between the inverter and the motor, or (3) enhance the insulation of the motor coil.

[Installation location and operating environment]

Avoid installation in areas of high temperature, excessive humidity, or where moisture can easily collect, as well as areas that are dusty, subject to corrosive gasses, mist of liquid for grinding, or salt. Install the inverter away from direct sunlight in a well-ventilated room that is free of vibration. The inverter can be operated in the ambient temperature range from –10 to 50°C. (Carrier frequency and output current must be reduced in the range of 40 to 50°C.)

A single-phase motor is not suitable for variable-speed operation by an inverter drive. Therefore, use a three-phase motor.

[Main power supply]

In the following examples involving a general-purpose inverter, a large peak current flows on the main power supply side, and may destroy the converter module. Where such situations are foreseen or the connected equipment must be highly reliable, install an AC reactor between the power supply and the inverter. Also, where influence of indirect lightning strike is possible, install a lightning conductor. (A) The unbalance factor of the power supply is 3% or higher. (Note) (B) The power supply capacity is at least 10 times greater than the inverter capacity (the power supply capacity is 500 kVA or more). (C) Abrupt power supply changes are expected.

Installation of an AC reactor on the input side

Examples: (1) Several inverters are interconnected with a short bus. (2) A thyristor converter and an inverter are interconnected with a short bus. (3) An installed phase advance capacitor opens and closes. In cases (A), (B) and (C), it is recommended to install an AC reactor on the main power supply side. Note: Example calculation with V

RS : R-S line voltage, VST : S-T line voltage, VTR : T-R line voltage

Unbalance factor of voltage = ———————————————————————

Using a private power generator

An inverter run by a private power generator may overheat the generator or suffer from a deformed output voltage waveform of the generator. Generally, the generator capacity should be five times that of the inverter (kVA) in a PWM control system, or six times greater in a PAM control system.

Notes on Peripheral Equipment Selection

(1)Be sure to connect main power wires with R(L1), S(L2), and T(L3) (input) terminals and motor wires to U(T1), V(T2), and

W(T3) terminals (output). (Incorrect connection will cause an immediate failure.) (2)Be sure to provide a grounding connection with the ground terminal ( ).

When an electromagnetic contactor is installed between the inverter and the motor, do not perform on-off switching during running operation.

When used with standard applicable output motors (Hitachi standard three-phase squirrel-cage four-pole motors), the L300P Series does not need a thermal relay for motor protection due to the internal electronic protective circuit. A thermal relay, however, should be used: during continuous running outside a range of 30 to 60 Hz. for motors exceeding the range of electronic thermal adjustment (rated current). when several motors are driven by the same inverter; install a thermal relay for each motor. The RC value of the thermal relay should be more than 1.1 times the rated current of the motor. Where the wiring length is 10 m or more, the thermal relay tends to turn off readily. In this case, provide an AC reactor on the output side or use a current sensor.

Install a circuit breaker on the main power input side to protect inverter wiring and ensure personal safety. Choose an inverter-compatible circuit breaker. The conventional type may malfunction due to harmonics from the inverter. For more information, consult the circuit breaker manufacturer.

The wiring distance between the inverter and the remote operator panel should be 20 meters or less. When this distance is exceeded, use CVD-E (current-voltage converter) or RCD-E (remote control device). Shielded cable should be used on the wiring. Beware of voltage drops on main circuit wires. (A large voltage drop reduces torque.)

Earth leakage relay

Phase advance capacitor

If the earth leakage relay (or earth leakage breaker) is used, it should have a sensitivity level of 15 mA or more (per inverter).

Do not use a capacitor for power factor improvement between the inverter and the motor because the high-frequency components of the inverter output may overheat or damage the capacitor

High-frequency Noise and Leakage Current

(1) High-frequency components are included in the input/output of the inverter main circuit, and they may cause interference in a transmitter, radio, or sensor if used near the inverter. The interference can be minimized by attaching noise filters (option) in the inverter circuitry. (2) The switching action of an inverter causes an increase in leakage current. Be sure to ground the inverter and the motor.

Lifetime of Primary Parts

Because a smoothing capacitor deteriorates as it undergoes internal chemical reaction, it should normally be replaced every five years. Be aware, however, that its life expectancy is considerably shorter when the inverter is subjected to such adverse factors as high temperatures or heavy loads exceeding the rated current of the inverter. The approximate lifetime of the capacitor is as shown in the figure at the right when it is used 12 hours daily (according to the “Instructions for Periodic Inspection of General-Purpose Inverter” (JEMA)). Also, such moving parts (cooling fan) should be replaced. Maintenance inspection and parts replacement must be performed by only specified trained personnel.

Precaution for Correct Usage

Before use, be sure to read through the Instruction Manual to insure proper use of the inverter. Note that the inverter requires electrical wiring; a trained specialist should carry out the wiring. The inverter in this catalog is designed for general industrial applications. For special applications in fields such as aircraft, outer space, nuclear power, electrical power, transport vehicles, clinics, and underwater equipment, please consult with us in advance. For application in a facility where human life is involved or serious losses may occur, make sure to provide safety devices to avoid a serious accident. The inverter is intended for use with a three-phase AC motor. For use with a load other than this, please consult with us.
