8 General SpecificationsMains supply (L1, L2, L3):Supply voltage 380-480 V +5%Mains voltage low / mains drop-out:During low mains voltage or a mains drop-out, the FC continues until the intermediate circuit voltage drops below the minimum stop level, whichcorresponds typically to 15% below the FC's lowest rated supply voltage. Power-up and full torque cannot be expected at mains voltage lower than10% below the FC's lowest rated supply voltage.Supply frequency 50/60 Hz ±5%Max. imbalance temporary between mains phases 3.0 % of rated supply voltageTrue Power Factor (λ) > 0.98 nominal at rated loadDisplacement Power Factor (cosφ) near unity (> 0.98)THiD < 5%Switching on input supply L1, L2, L3 (power-ups) maximum once/2 min.Environment according to EN60664-1 overvoltage category III / pollution degree 2The unit is suitable for use on a circuit capable of delivering not more than 100.000 RMS symmetrical Amperes, 480/690 V maximum.Motor output (U, V, W):Output voltage 0 - 100% of supply voltageOutput frequency 0 - 800* HzSwitching on output UnlimitedRamp times 1 - 3600 sec.* Voltage and power dependentTorque characteristics:Starting torque (Constant torque) maximum 110% for 1 min.*Starting torque maximum 135% up to 0.5 sec.*Overload torque (Constant torque) maximum 110% for 1 min.**Percentage relates to the frequency converter's nominal torque.Cable lengths and cross sections:Max. motor cable length, screened/armoured 150 mMax. motor cable length, unscreened/unarmoured 300 mMax. cross section to motor, mains, load sharing and brake *Maximum cross section to control terminals, rigid wire 1.5 mm2/16 AWG (2 x 0.75 mm2)Maximum cross section to control terminals, flexible cable 1 mm2/18 AWGMaximum cross section to control terminals, cable with enclosed core 0.5 mm2/20 AWGMinimum cross section to control terminals 0.25 mm2* See Mains Supply tables for more information!Digital inputs:Programmable digital inputs 4 (6)Terminal number 18, 19, 27 1), 29 1), 32, 33,Logic PNP or NPNVoltage level 0 - 24 V DCVoltage level, logic'0' PNP < 5 V DCVoltage level, logic'1' PNP > 10 V DCVoltage level, logic '0' NPN > 19 V DCVoltage level, logic '1' NPN < 14 V DCMaximum voltage on input 28 V DCInput resistance, Ri approx. 4 kΩAll digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.1) Terminals 27 and 29 can also be programmed as output.VLT HVAC Low Harmonic Drive Operating In-structions 8 General SpecificationsMG.16.A1.02 - VLT® is a registered Danfoss trademark 1618
