CHAPTER 2

CHAPTER 2 - GENERAL INFORMATION

2.3 ABOUT THE CFW-10

The CFW-10 frequency inverter is fitted with the V/F (scalar) control method. The V/F (scalar) mode is recommended for more simple applications such as pump andfan drives. In these cases one can reduce the motor and inverter losses by using the "Quadratic V/F" option, that results in energy saving. The V/F mode is also used when more than one motor should be driven simultaneously by one inverter (multimotor application). Chapter 9 shows the different power lines and additional technical information The block diagram below gives a general overview of the CFW-10.

Avoid direct exposure to sunlight, rain, high moisture and sea air. Avoid exposure to gases or explosive or corrosive liquids; Avoid exposure to excessive vibration, dust, oil or any conductive particles or materials.

Environmental Conditions:

Temperature : 0 ºC to 50 ºC (32 ºF to 122 ºF) - nominal conditions, except for the 15.2 A model with Built-in filter (0 to 40 °C). Relative Air Humidity: 5 % to 90 % - non-condensing. Maximum Altitude: 1000 m (3.300 ft) - nominal conditions. From 1000 m to 4000 m (3.300 ft to 13.200 ft): with 1 % current derating for each 100 m (330 ft) above 1000 m (3.300 ft). Pollution Degree: 2 (according to EN50178 and UL508C).

External dimensions and mounting holes for the CFW-10 shall be according to figure 3.1 and table 3.1.
