Air Compressor

Products

[L700]

(Extinction)L700 series

High-performance inverter that can be widely applied not only for FAN and PUMP but also for conveyor

Product Infomation

 - FAN, PUMP as well as conveyor applications is also applicable to a wide range of high-performance inverter 

- 3-phase 200V class: 11 ~ 75kW 

- 3-phase 400V class: 11 ~ 160kW 

 

FAN, PUMP widely as possible to respond to applications as conveyor


1. startup torque 0.5Hz / 150% power operation

 - sensor-less vector control equipped with a constant torque can be applied to applications available power operation 

 * 90kW or more: 0.5Hz / 120%


2 . trip inhibition achieved stable operation

 - over-current and over-voltage suppression

 - DC BUS AVR function during deceleration


3. the parent device does not need to program operation function

 - Simple operation sequence realize

 - automatic operation for accelerating the load situations such as cranes or conveyors can also be

 the parent device, peripheral it is possible to simplify the circuit and contributes to space savings in the control panel


4. built into inverter circuit around

 - built-in noise reduction regenerative braking circuit (BRD) to the EMC noise filter generated by the inverter equipped with a standard(less than 30kW)

 - micro surge voltage suppression


5. simple maintenance

 - simple structure with removable cooling fan, smoothing capacitor, the control terminal

 - maintenance more easy

 - and long life by adopting a component design life of 10 years realizing

 - the cooling oN / OFF control can be further extended to the life of the fan

 - condenser , the aging degree of the cooling fan, cooling fan motor and

 - can monitor the temperature rising

 - life warning improve the ease of maintenance by the signal


6. simple parameter setting

 - data comparison feature, the user selection, the default mode

 - easy operation the ability of such


7. network faithfully respond

 - RS-485

 - Modbus-RTU as standard on the corresponding port

 - option can respond by DeviceNet, PROFIBUS, CC-Link board on the

 - Open network for possible


8. environmental consideration

 - EU RoHS Directive correspondence

 - in improving environmental performance



■ characteristics of Hitachi low-voltage inverter


1. trip faithful suppression

- overcurrent and overvoltage suppression by high starting torque and current control, with more than 0.5 Hz 200% driven by a strong reinforcement the operation function is realized.

※ full-load operation when multiple non-inverter protection IGBT module damaged even if the output short-circuit functions employed (Hitachi patented)


2. input signal enhancement

- analog (current / voltage) to increase output monitor (AM / AMI terminal) to an emergency resolution It was equipped with a blocking function.

- Do not leave the built-in CPU (software) on the intelligent input terminals on the middle inverter output only hardware circuitry can be blocked.


3. The program operation function

- to download the program to the inverter can be simplified sequence of operation and accelerator operation can be automatic, depending on load conditions can be simplified and the host device, a peripheral circuit.


4. The peripheral circuit built into inverter

- was EMC filter and built-in video core to the AC power input, and expanded the internal model of the regenerative braking circuit (BRD).

- WJ200: full capacity, SJ700: 22Kw or less, L700: 30Kw or less


5. Micro-surge voltage suppression function

- suppresses the motor terminal voltage control pwm by Hitachi's unique approach to the control pulse 2 times or less of the DC voltage.


6. Simple maintenance

- cooling fan, simple replacement of the smoothing capacitor and the maintenance can be simple wiring without a detachable screw terminal board even more easily.


7. Life diagnostics Jobs

- was adopted to realize the long-lived component design life of 10 years, temperatures, and cooling fan motor temperature rise by the lifetime diagnostics is life warning signals such as output.


8. The improvement in environmental performance

- within the substrate part of the varnish coating, plating the copper bar to the adoption of the standard has improved environmental resistance.


9. The global response 

- suited to the world standards (CE, UL, C-UL ) , and you can respond to an open network of DeviceNet, Profibus etc.
