4.5 General SpecificationsMains supply (L1, L2, L3):Supply voltage 200-240 V ±10%Supply voltage AutomationDrive FC 301: 380-480 V / AutomationDrive FC 302: 380-500 V ±10%Supply voltage AutomationDrive FC 302: 525-690 V ±10%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) ≥ 0.9 nominal at rated loadDisplacement Power Factor (cos ϕ) near unity (> 0.98)Switching on input supply L1, L2, L3 (power-ups) ≤ 7.5 kW maximum 2 times/min.Switching on input supply L1, L2, L3 (power-ups) 11-75 kW maximum 1 time/min.Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW maximum 1 time/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, 240/500/600/ 690 V maximum.Motor output (U, V, W):Output voltage 0 - 100% of supply voltageOutput frequency (0.25-75 kW) AutomationDrive FC 301: 0.2 - 1000 Hz / AutomationDrive FC 302: 0 - 1000 HzOutput frequency (90-1000 kW) 0 - 800* HzOutput frequency in Flux Mode (AutomationDrive FC 302 only) 0 - 300 HzSwitching on output UnlimitedRamp times 0.01 - 3600 sec.* Voltage and power dependentTorque characteristics:Starting torque (Constant torque) maximum 160% for 60 sec.*Starting torque maximum 180% up to 0.5 sec.*Overload torque (Constant torque) maximum 160% for 60 sec.*Starting torque (Variable torque) maximum 110% for 60 sec.*Overload torque (Variable torque) maximum 110% for 60 sec.*Percentage relates to the nominal torque.Cable lengths and cross sections for control cables*:Max. motor cable length, screened AutomationDrive FC 301: 50 m / AutomationDrive FC 301 (A1): 25 m/ AutomationDrive FC 302: 150 mMax. motor cable length, unscreened AutomationDrive FC 301: 75 m / AutomationDrive FC 301 (A1): 50 m/ AutomationDrive FC 302: 300 mMaximum cross section to control terminals, flexible/ rigid wire without cable end sleeves 1.5 mm2/16 AWGMaximum cross section to control terminals, flexible wire with cable end sleeves 1 mm2 /18 AWGMaximum cross section to control terminals, flexible wire with cable end sleeves with collar 0.5 mm2 /20 AWGMinimum cross section to control terminals 0.25 mm2 / 24 AWG* Power cables, see tables in section “Electrical Data” of the Design Guide4 AutomationDrive FC 300 Selection FC 300 Design Guide78 MG.33.BC.02 - VLT® is a registered Danfoss trademark4
