Words used In Specifications
Spec. No.
The "Spec No." shows the revision number for the specification sheet. Each documented specification carries an area of revision history in the upper right corner of the top page. The specifications of the standard models are subject to change without prior notice, so, please check if the revision number of your specification is the latest version before evaluating it.
Absolute Maximum Ratings
The "Absolute Maximum Ratings" refer to values that must not be exceeded in any event. Using a VFD in excess of the specified rating may lead to its permanent breakdown. Therefore, high reliability will be secured if special attention is paid to the design of a power supply circuit, possible fluctuations in the supply voltage, surrounding components, operating temperature, environment surges or spikes, etc.
Rating or Recommended Operating Conditions
The "Rating" or "Recommended Operating Conditions" represent the specification of a recommended operating condition that guarantees the operation of the VFD. It also serves as a test condition for which the product is subjected prior to shipment from the factory. Therefore, it should be noted that if a VFD is used in excess of the maximum or minimum rating specified here, its operation and quality will not generally be guaranteed even when it remains within the absolute maximum rating.
In addition, this rated value has been defined assuming the most standard service conditions by users. However, some may want to study the possibility of using the VFDs outside the rated value, prompted by a desired individual requirement. In such a case, please feel free to consult with us, as we may be willing to discuss the possibility of the proposed specifications.
Block Diagram
It shows how to connect the power supplies. The basic circuit used in factory inspection is the same as this one.
Electrical (and Optical) Characteristics
All of numbers specified in this section shows the characteristics when the CIG VFDs are tested under the typical (TYP) operating conditions unless otherwise noted.
Timing Chart
It shows the AC characteristics and relationship of interface operations.
Serial Data Format
It shows the shift register and segment or grid assignment, and how to control these data to optimize grid scan.
