Product Description:
The VLT 3002 is a variable frequency drive produced by Danfoss and assigned to the VLT 3000 Variable Speed Drives series. It is designed to regulate the speed of small three-phase induction motors, providing closed-loop process control in automated lines, ventilation systems, and material-handling cells. By varying output frequency and voltage, the drive minimizes mechanical wear, keeps energy use proportional to demand, and integrates cleanly into standard control cabinets.
Under nominal conditions, the drive delivers a typical shaft output of 1.1 kW, while overall conversion efficiency reaches 0.96, so only about 60 W of power is dissipated as heat at full load. Acoustic noise is limited to 38 dBA, supporting installation near operator workstations. Control electronics are powered from an isolated 24 V DC supply that may draw up to 140 mA. Reference circuits provide 10 V DC to external potentiometers with a maximum sourcing capability of 17 mA. Command channels follow discrete logic; each digital input presents 2 kΩ of resistance, whereas analog voltage inputs exhibit 10 kΩ, protecting PLC outputs from excessive load. The input switching rate is limited to two times per minute to prevent capacitor stress during frequent energization.
For field wiring, the terminal block accepts motor cables up to 2.5 mm² and supports shielded runs of 150 m or unshielded runs of 300 m without jeopardizing output waveform integrity. Shielded cabling helps reduce electromagnetic interference when the drive is installed near sensitive control or communication circuits. After the inverter is powered down, users must observe a discharge wait time of four minutes before touching conductors because the internal capacitors may retain hazardous voltage. Mechanical endurance is verified at 0.7 g during vibration testing, confirming suitability for panels subject to continuous machine vibration. Secure mounting and proper cable routing help prevent connector strain in industrial enclosures exposed to sustained movement.
