Product Description:
The VLT 3060 is a variable frequency drive produced by Danfoss as part of the VLT 3000 Variable Speed Drives series. This AC inverter is installed between the plant power bus and a three-phase induction motor, where it modulates the supplied voltage to control the speed of conveyors, pumps, and material-handling equipment without mechanical throttling or gear changes. By delivering a controlled pulse-width-modulated output, the unit allows control systems to adjust motor torque, acceleration, and deceleration profiles to match process demands.
With an operating efficiency of 0.96, the drive minimizes heat loss while delivering the commanded power level. Its output frequency spans 0 to 120 Hz in standard mode and extends to 0 to 500 Hz for applications requiring high-speed or very-low-speed operation. Motor circuit protection is provided by a 150 A prefuse, and the input section accepts a symmetrical three-phase supply of 3 × 380/400/415/440/460/500 V ±10%. Despite its enclosure weight of 323 lb, the unit can be mounted in a suitable industrial cabinet. The drive operates with a supply frequency of 50 or 60 Hz and produces rated motor voltages ranging from 380 V to 500 V. Its output voltage can be adjusted from 0 to 100 percent of the incoming supply voltage.
The switching devices inside the inverter operate at a maximum carrier frequency of 4.5 kHz, balancing acoustic noise with semiconductor losses. The drive accommodates motor leads up to 300 m long with a maximum cross-sectional area of 70 mm², while the supply side permits conductors with a cross-sectional area of up to 120 mm². Programmable acceleration and deceleration ramps ranging from 0.1 to 3600 seconds allow precise control of startup and stopping stresses. A displacement power factor of 0.9/1.0 keeps reactive demand low on the supply transformer. Available settings include rated motor frequencies of 50, 60, 87, or 100 Hz, allowing the voltage-to-frequency profile to remain consistent across the full output voltage range.
