The Eaton Cutler-Hammer HVX003A1-2A1B1 drive is part of the HVX 9000 Drive series. The catalog number indicates certain traits. The first 3 letters (HVX) indicates the product family of the device. The next 3 numbers (003) indicate the motor or horsepower rating which for this device is 3HP or 2.2 kW. The next letter (A) indicates that this drive uses standard software. The (1) is the type of enclosure used (an IP21 (NEMA 1) type.) The next number (2) is for the voltage rating, which is 230V and is operational between -15% and 10% (208 and 240V). The last letter (A) stands for the drive’s alphanumeric keypad. The (1) after it indicates what input option is available. For this drive, the input option is 1. Input option 1 includes parameters for analog input 1(AI1) and digital input 1. Input option 1 is also available for Electro Magnetic Compatibility (EMC) Class H and in 3-phase input voltage. The letter (B) indicates that an internal brake chopper circuit is included in this type of drive. The braking chopper is for receiving the inertia of the motor and for when the load on the drive is decelerating the motor. The last number (1) is for board modifications which use a standard board.

The power connection of the HVX003A1-2A1B1 includes an input frequency which ranges between 50 and 60 Hz and has a variation of 45 – 60 Hz. In a normal operation, it is up to 1 per minute or less when it comes to connecting to power. The output voltage is adjustable from 0V to the input voltage level and the output frequency is adjustable from 0-320 Hz. The motor torque start-up is at 110%. The HVX003A1-2A1B1 has a frequency resolution of 0.0.1 Hz, overall dimensions of 12.9in (327mm) for the height, 7.5in (190mm) for the depth, and 5in (128mm) for the width, and it weighs up to 11lb (5kg).
