6.2 General SpecificationsMains supply (L1, L2, L3)Supply Terminals L1, L2, L3Supply voltage 380-480 V:-15% (-25%)1) to +10%1) The frequency converter can run at -25% input voltage with reduced performance. The maximum output power of thefrequency converter is 75% in case of -25% input voltage and 85% in case of -15% input voltage.Mains voltage low/mains drop-out:During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage dropsbelow the minimum stop level, which corresponds typically to 15% below the frequency converter's lowest rated supply voltage.Full torque cannot be expected at mains voltage lower than 10% below the frequency converter'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.The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 480 V maximum.Motor output (U, V, W)Output voltage 0-100% of supply voltageOutput frequency (0.37-75 kW) 0-500 HzOutput frequency in VVCplus Mode 0-200 HzSwitching on output UnlimitedRamp times 0.01-3600 sTorque characteristicsStarting torque (constant torque) maximum 160% for 60 s1)Overload torque (constant torque) maximum 160% for 60 s1)Starting torque (variable torque) maximum 110% for 60 s1)Overload torque (variable torque) maximum 110% for 60 sStarting current maximum 200% for 1 sTorque rise time in VVCplus (independent of fsw) 10 ms1) Percentage relates to the nominal torque.2) The torque response time depends on application and load but as a general rule, the torque step from 0 to reference is 4-5 xtorque rise time.Control cable lengths and cross sections1)Max. motor cable length, screened 50 mMax. motor cable length, unscreened 100 mMaximum cross section to control terminals, flexible/rigid wire 2.5 mm2/14 AWGMinimum cross section to control terminals 0.55 mm2/ 30 AWG1) For power cables, see Table 6.1 to Table 6.3.Digital inputsProgrammable digital inputs 7Terminal number 18, 19, 271), 291), 32, 33, 31Logic 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' NPN2) > 19 V DCVoltage level, logic '1' NPN2) < 14 V DCMaximum voltage on input 28 V DCPulse frequency range 4 Hz-32 kHz(Duty cycle) Min. pulse width 4.5 msSpecifications VLT® AutomationDrive FC 360 Design GuideMG06B202 - VLT® is a registered Danfoss trademark 696 6
