1) Optimal, 2) Suitable

 

 

HVAC

Heating, ventilation and air conditioning systems primary purpose is to control the building or factories’ temperature and humidity.

A refrigerator requires diverse analogue inputs and contact outputs for constant temperature control.

As a drive exclusive for HVAC, the H100 has exclusive functions including a reservation function, advanced PID, Master/Follower etc

Recommended HVAC Inverter: H100

 

Metals & Material

Metals are composed of ID/FD Fan/Pump for cooling from the stages of transferring raw materials (conveyor or hoist), casting and winding.

Unlike other load types, the load type of metals is larger, heavier and greater in tension. Thus, products that are equipped with sensor-less and sensored vector control, as well as helper roll and winding control, are needed.

Recommended Metals & Material Inverters: iS7/iV5/iG5A/iC5

 

Elevator & Escalator

It is a power device used to transport persons or cargo, which consists of an (ultra) high-speed unit for passengers, (medium) low-speed unit for passengers, a unit for view; for hospitals; for cargo; for vehicles and dumbwaiter.

Recommended Elevator & Escalator Inverter: iV5/iV5L/iS7

 

Textiles

There are a wide range of processes including threading, drawing, yarn, dyeing, warping, beaming, weaving (loom), inspecting grey goods, refining, reducing, washing, dyeing and stenter machine process, so various loads ranging from the low-end load to high-end load of winders and twisters exist.

As there are a lot of high temperature and humidity environments being corrosion resistance and waterproof are required.

Recommended Textiles Inverter: H100/iS7/iV5/iV5L/S100/iG5A

  • For VT load: H100;
  • For CT load: iS7/iV5/iV5;
  • For low-capacity load: S100/iG5A

Products that meet various process features.

In particular, iS7, S100 built-in with S/W exclusive for winders uses WEB PID for precise winding. All inverters are applied with PCB Conformal Coating.

 

Plastic & Rubber

There are processes such as injection moulding to create a model by melting raw materials or winding the produced artificial thread and printed films.

A part of injection moulding is mixed with servo systems for use, and it requires an accurate position control or torque control.

Recommended Plastic & Rubber Inverters: iS7/S100/iG5A

iS7 installed with S/W exclusive for winders along with synchronisation and position control is one of the representative products. S100 built-in with S/W only for winders is also used.

It is recommended to use iG5a or equivalent for small-capacity helper roll and conveyor.

 

Energy

HVAC load is the major part of energy and the load of ID/FD Fan/Pump applied for power generation industry and the load that goes along with the high-efficiency system in the local environment are the main components

Recommended Energy Inverters: H100/iS7

High-efficiency inverter is recommended for energy applications. iS7 may be used to respond to CT Load. Without a separate controller, a built-in PID is capable of controlling pressure and flow.

 

Marine

When the distributed control system was introduced in 1990’s automated processes were realised in various systems, including automatic and power control of generators; ballast and pump motors for cargo; and valve control. As environmental regulations came into effect, the needs for auto control and energy efficiency have been accelerated.

Recommended Marine Inverter: iS7

These products that have obtained the certificate of classification are included in a lineup which is gradually applied in the shipping industry.

Based on the classification, the products have satisfied the power and environmental requirements necessary for ship installation. Also, there are reference cases of applying the products for merchant ships and marine cranes

 

Food & Beverage

High-performance IP products with a high-pressure jet function for washing are required for food sanitation and contamination prevention. Furthermore, there is a growing demand for drives with functions such as accurate positioning and synchronising of packing machines, labelling machines and conveyors.

Recommended Food & Beverage Inverters: iS7/S100

 

Pulp & Paper

In general, it is a load with smaller tension when compared with steel so precise control and fast responsiveness are needed. In most cases, it is fabricated as a System Drive (AFE + DC-type inverter). DC input-type inverter products or any product with a DC input function may be applied.

Wood or raw materials that have completed primary operation are chemically treated to prodcue paper, artificial fibre and etc

Recommended Pulp & Paper Inverters: iS7/iV5

 

Mining

Anti-environment properties such as explosion, dust and water resistance are needed and higher reliability with an application of a long distance line is required.

In the of excavators operated underground, high performance and reliable drives are needed to respond to high-torque, heavy-duty loads.

The LS iS7 inverter has been used in subway construction, submarine tunnel and underground line construction, and high powered devices where torque-synchronised operation is applicable.

Recommended Mining Inverter: iS7

 

Oil & Gas Chemical

High-capacity power and long-distance line application are needed when applied to large plants. The Inverter should be highly reliable when it comes to risk including fire accidents as large-capacity products are applied for air conditioning, pump and production. LS drives have been used in petrochemical and oil refining industry, and LS offer various options and large-capacity products with the Drive System-applied technologies.

Recommended Oil & Gas Chemical Inverters: iS7/H100

 

Crane & Hoist

3 basic operation modes include hoist, gantry and trolley, and there is an additional function, boom up/down, for marine cranes.

Although features required for inverters differ according to the operation mode, they generally transport heavy cargo. Thus it is recommended to use sensor-less and sensored vector mode.

Recommended Crane & Hoist Inverters:  iS7/iV5/S100

 

Water & Wastewater

Harmful gases generated upon sewage treatment should be prevented (coating), and it is HVAC App that generally requires a low level of THD (AFE, Low Harmonic Drive)

Recommended Water & Wastewater Inverter: H100
