Q. How will I know if my application will require resistive braking?

 

 

 

 

A. For new applications, it may be difficult to tell before you actually test a

started

 

 

 

motor/drive solution. In general, some application can rely on system losses

 

 

 

long decel time. These applications will not need dynamic braking.

 

 

 

 

 

such as friction to serve as the deceleration force, or otherwise can tolerate a

However, applications with a combination of a high-inertia load and a required

 

 

 

short decel time will need dynamic braking. This is a physics question that

 

 

 

may be answered either empirically or through extensive calculations.

Q. Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application require any of these options?

A. The purpose of these noise filters is to reduce the inverter electrical noise so the operation of nearby electrical devices is not affected. Some applications are governed by particular regulatory agencies, and noise suppression is mandatory . in those cases, the inverter must have the corresponding noise filter installed. Other applications may not need noise suppression, unless you notice electrical interference with the operation of other devices.

Q. The X200 features a PID control. PID loops are usually associated with chemical processes, heating, or process industries in general. How could the PID loop feature be useful in my application?

A. You will need to determine the particular main variable in your application the motor affects. That is the process variable (PV) for the motor. Over time, a faster motor speed will cause a faster change in the PV than a slow motor speed will. By using the PID loop feature, the inverter commands the motor to run at the optimal speed required to maintain the PV at the desired value for current conditions. Using the PID loop feature will require an additional sensor and other wiring, and is considered an advanced application.

CP-X200 specifications

The Hitachi CP-X200 is a versatile and robust projector designed to cater to the needs of educational and business environments. It combines affordability with high-quality performance, making it an attractive option for various presentations and multimedia applications.

At the heart of the CP-X200 is its high brightness capability, with a lumen output of 3,000 ANSI lumens. This feature enables the projector to deliver clear and vibrant images even in well-lit rooms. The resolution of XGA (1024 x 768 pixels) ensures that text and graphics are sharp, making it suitable for everything from classroom lectures to corporate presentations.

One of the standout characteristics of the Hitachi CP-X200 is its advanced lamp technology. The projector uses a long-lasting lamp that can provide up to 5,000 hours of usage in standard mode, allowing for extended intervals between lamp replacements. Additionally, the ECO mode can further enhance the lamp life, extending its longevity while reducing energy consumption.

The CP-X200 is equipped with a variety of connectivity options, including HDMI, VGA, and composite inputs, allowing users to easily connect it to various devices such as laptops, DVD players, and other multimedia systems. The inclusion of USB and RS-232 interfaces ensures compatibility with different control systems, making it a flexible choice for diverse setups.

Another significant feature is the projector's built-in 10-watt speaker, which provides decent audio output, eliminating the need for external speakers in smaller venues. The speaker system enhances presentations, ensuring that audio and visuals are cohesive, promoting better audience engagement.

Portability is another key aspect of the Hitachi CP-X200, which weighs just around 3.5 kg (approximately 7.7 lbs), allowing for easy transport between locations. Its compact design makes it suitable for both fixed installations and mobile use, catering to professionals who require a projector that adapts to various environments.

The user-friendly interface and robust remote control enhance the projector's operability, providing easy access to essential functions. Additionally, features such as auto keystone correction adjust the image to maintain consistent quality even when the projector is not perfectly aligned with the screen.

In summary, the Hitachi CP-X200 is a feature-rich projector that embodies reliability, performance, and ease of use. Its combination of high brightness, various connectivity options, long lamp life, portability, and integrated audio makes it an excellent choice for education and business professionals seeking a dependable presentation solution.
