Note 1: 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 2: 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 3: The braking torque via capacitive feedback is the average deceleration torque at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking torque. The average decel torque varies with motor loss. This value decreases when operating beyond 50 Hz. Note 4: The protection method conforms to JEM 1030.
Note 5: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the maximum allowable rotation speed. Note 6: The output frequency may exceed the maximum frequency setting (A004 or A204) for automatic stabilization control. Note 7: At the rated voltage when using a Hitachi standard 3-phase, 4pole motor. Note 8: DC 4 to 20 mA Input, need parameter setting by Keypad etc. Analog input voltage or current can be switched by switch as individually and not use them in the same time.

Cause(s)
Name
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.
While at constant speed During deceleration During acceleration Others
Overload protection *1 Over voltage protection Memory error *2,3 Under-voltage error Current detection error CPU error External trip USP *4 Ground fault *5 Input over-voltage Inverter thermal detection system error
When a motor overload is detected by the electronic thermal function, the inverter trips and turns OFF its output. When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor. When the built-in memory has problems due to noise or excessive temperature, the inverter trips and turns OFF its output to the motor. 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 an error occurs in the internal current detection system, the inverter will shut off its output and display the error code. A malfunction in the built-in CPU has occurred, so the inverter trips and turns OFF its output to the motor. A signal on an intelligent input terminal configured as EXT has occurred. The inverter trips and turns OFF the output to the motor. When the Unattended Start Protection (USP) is enabled, an error occurred when power is applied while a Run signal is present. The inverter trips and does not go into Run Mode until the error is cleared. The inverter is protected by the detection of ground faults between the inverter output and the motor during powerup tests. This feature protects the inverter, and does not protect humans. When the input voltage is higher than the specified value, it is detected 100 seconds after powerup and the inverter trips and turns OFF its output. When the cooling fin thermal sensor in the inverter detect disconnection etc, inverter trips.
Inverter thermal trip
When the inverter internal temperature is above the threshold, the thermal sensor in the inverter module detects the excessive temperature of the power devices and trips, turning the inverter output OFF.
Control circuit error
When abnormality occurred on a control circuit board, I make a error code
Driver error Output phase loss protection Low-speed overload protection Operator connection failure Communications error
An internal inverter error has occurred at the safety protection circuit between the CPU and main driver unit. Excessive electrical noise may be the cause. The inverter has turned OFF the IGBT module output. Output Phase Loss Logic Detection (There are undetectable terms of use.) If overload occurs during the motor operation at a very low speed, the inverter will detect the overload and shut off the inverter output. When the connection between inverter and operator keypad failed, inverter trips and displays the error code. The inverter's watchdog timer for the communications network has timed out.
Note 1: Reset operations acceptable 10 seconds after the trip. Note 2: If an memory error (E08) occurs, be sure to confirm the parameter data values are still correct. Note 3: Memory error may occer at power-on after shutting down the power while copying data with remote operator or initializing data. Shut down the power after completing copy or initialization. Note 4: USP error occures at reseting trip after under-voltage error (E09) if USP is enabled. Reset once more to recover. Note 5: Ground fault error (E14) cannot be released with resetting. Shut the power and check wiring. Note 6: When error E08 error, it may be required to perform initialization.

Electrical noise interference may occur on nearby equipment such as a radio receiver. This magnetic choke filter helps reduce radiat-ed noise (can also be used on output).
Suppresses harmonics generated by the inverter. Reduces radiated noise from wiring in the inverter output 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 input). This reactor reduces the vibration in the motor caused by the inver-ter's switching waveforms, by smoothing the waveforms to approximate commercial power quality. It is also useful when wiring from the inverter to the motor is more than 10m in length, to reduce harmonics. Sine wave shaping filter for the output side.

For Correct Operation Application to Motors Application to general-purpose motors Operating frequency
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.
Torque characteristics
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.
Motor loss and temperature increase
The torque characteristics of driving a general-purpose motor with an inverter differ from those of driving it using commercial power
Noise
When run by an inverter, a general-purpose motor generates noise slightly greater than with commercial power.
Vibration
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.
Power transmission mechanism
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.
Application to special motors Gear motor Brake-equipped motor
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.
Pole-change motor
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. Also see: Application to the 400V-class motor.
Submersible 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.
Explosion-proof 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 of motor. *Explosion-proof verification is not available for NE-S1 Series.
Synchronous (MS) motor High-speed (HFM) motor
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.
Single-phase motor
A single-phase motor is not suitable for variable-speed operation by an inverter drive. Therefore, use a three-phase motor.
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.
Notes on Use Drive Run/Stop
Run or stop of the inverter must be done with the keys on the operator panel or through the control circuit terminal. Do not operate by installing a electromagnetic contactor (MC) in the main circuit.
Emergency motor stop
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.
High-frequency run
A max. 400Hz can be selected on the NE-S1 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. A full line of high-speed motors is available from Hitachi.
About the load of a frequent repetition use About frequent repetition use (crane, elevator, press, washing machine) , a power semiconductor (IGBT, a rectification diode, thyristor) in the inverter may come to remarkably have a short life by heat exhaustion. The life can be prolonged by lower a load electric current. Lengthen acceleration / deceleration time. Lower carrier frequency. or increasing capacity of the inverter.
About the use in highlands beyond 1,000m above sea level When the standard inverter is used at a place beyond 1,000m above sea level because it cool heating element with air, please be careful as follows. But please inquire for the highlands more than 2,500m separately. 1. Reduction of the inverter rating current The density of air decreases by 1% whenever rising by 100m when the altitude exceeds 1000m. For example, in the case of 2,000m above sea level, it is {2,000(m) -Because it becomes 1,000(m)}/100(m) X {-1(%)} =-10(%), please use with 10(%) reduction (0.9* inverter rating electric current) of a rating current of the inverter. 2. Reduction of the breakdown voltage When using inverter at a place beyond 1,000m, the breakdown voltage decreases as follows. 1,000m or less:1.00/1,500m:0.95/2,000m:0.90/2,50 0m:0.85. But please do not perform the withstand pressure test as mention of the instruction manual.

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.)
Main power supply
Installation of an AC reactor on the input side
In the following examples involving a general-purpose inverter, a large peak current flows on the main power supply side, and is able to 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. 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 VRS = 205V, VST = 201V, VTR = 200V VRS : R-S line voltage, VST : S-T line voltage, VTR : T-R line voltage Max. line voltage (min.) - Mean line voltage x100 Mean line voltage 205-202 VRS-(VRS+VST+VTR)/3 x100 = = x100 =1.5(%) 202 (VRS+VST+VTR)/3
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 Wiring connections Electromagnetic contactor
(1) Be sure to connect main power wires with R(L1), S(L2), and T(L3) terminals (input) 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 (standard three-phase squirrel-cage four-pole motors), the NE-S1 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.
Installing a circuit breaker
Install a circuit breaker on the main power input side to protect inverter wiring and ensure personal safety. Choose an invertercompatible circuit breaker. The conventional type may malfunction due to harmonics from the inverter. For more information, consult the circuit breaker manufacturer.
IWiring distance
The wiring distance between the inverter and the remote operator panel should be 20 meters or less. Shielded cable should be used on thewiring. 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.
Because a DC bus 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 as a cooling fan should be replaced. Maintenance inspection and parts replacement must beperformed by only specified trained personnel. Please plan to replace new INV depends on the load, ambient condition in advance.
