Frequently Asked Questions

 

 

 

 

Q. What is the main advantage in using an inverter to drive a motor, compared to

alternative solutions?

 

 

A. An inverter can vary the motor speed with very little loss of efficiency, unlike

mechanical or hydraulic speed control solutions. The resulting energy savings

 

 

 

usually pays for the inverter in a relatively short time.

 

 

 

 

 

Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier” to describe the electronic unit that controls a motor. What does “inverter” mean?

A. The term inverter, drive, and amplifier are used somewhat interchangeably in industry. Nowadays, the term drive, variable-frequency drive, variable-speed drive, and inverter are generally used to describe electronic, microprocessor- based motor speed controllers. In the past, variable-speed drive also referred to various mechanical means to vary speed. Amplifier is a term almost exclusively used to describe drives for servo or stepper motors.

Q. Although the X200 inverter is a variable speed drive, can I use it in a fixed-speed application?

A. Yes, sometimes an inverter can be used simply as a “soft-start” device, providing controlled acceleration and deceleration to a fixed speed. Other functions of the X200 may be useful in such applications, as well. However, using a variable speed drive can benefit many types of industrial and commercial motor applications, by providing controlled acceleration and deceleration, high torque at low speeds, and energy savings over alternative solutions.

Q. Can I use an inverter and AC induction motor in a positioning application?

A. That depends on the required precision, and the slowest speed the motor must turn and still deliver torque. The X200 inverter will deliver full torque while turning the motor at 6Hz (180RPM). DO NOT use an inverter if you need the motor to stop and hold the load position without the aid of a mechanical brake (use a servo or stepper motion control system).

Q. Can the inverter be controlled and monitored via a network?

A. Yes. X200 inverters have built-in ModBus communications. See Appendix B for more information on network communications.

Q. Why does the manual or other documentation use terminology such as “200V class” instead of naming the actual voltage, such as “230 VAC”

A. A specific inverter model is set at the factory to work across a voltage range particular to the destination country for that model. The model specifications are on the label on the side of the inverter. A European 200V class inverter (“EU” marking) has different parameter settings than a USA 200V class.

NOTE: The European 200V class inverter is for single phase input (-SFE), while the USA 200V class inverter is for 3/single phase input (-NFU up to 2.2kW) and 3-phase input (-LFU) 3.7kW.

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.
