Controlled Stop Operation at Power Loss

Controlled stop operation at power loss helps avoid tripping or free-running (coasting) of the motor when power is lost while in run mode. The inverter controls the internal DC bus voltage while decelerating the motor, and brings the motor to a controlled stop.

Should power be lost while the inverter is in run mode, this function will have the following effect:

cWhen the internal DC bus voltage of the inverter comes down to the set level of B051, the inverter decreases the output frequency by the amount set in B054. (During this interval the DC bus voltage rises due to regeneration, so does not reach the UV level.)

dThe inverter then continues deceleration according to the value set in B053. If the DC bus voltage rises up to the set value of B052, the inverter stops deceleration to avoid OV tripping.

eDuring this interval, the DC bus voltage decreases again due to lack of input power.

fWhen the DC bus voltage comes down to the set value of B051, the inverter starts deceleration according to the set value of B053 again. This process will be repeated as needed until the motor is brought to a stop.

NOTE: If the DC bus voltage comes down to the UV level during this operation, the inverter trips with under-voltage and motor will free-run (coast) to a stop.

NOTE: If the set value of B052<B051, then the inverter internally swaps the B052 and B051 values. However the displayed values are not changed.

NOTE: This function cannot be interrupted until it is completed. So if the power is restored during this operation, wait until the operation is done (motor stops) and then give the run command.

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.
