9.2 General SpecificationsMains supply (L1, L2, L3)Supply voltage 200-240 V ±10%, 380-480 V ±10%, 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 minimumstop level, which corresponds typically to 15% below the FC's lowest rated supply voltage. Power-up and full torque cannot beexpected at mains voltage lower than 10% 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 () ≥ 0.9 nominal at rated loadDisplacement Power Factor (cos) near unity (> 0.98)Switching on input supply L1, L2, L3 (power-ups) ≤ enclosure type A maximum twice/min.Switching on input supply L1, L2, L3 (power-ups) ≥ enclosure type B, C maximum once/min.Switching on input supply L1, L2, L3 (power-ups) ≥ enclosure type D, E, F 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, 480/600 Vmaximum.Motor output (U, V, W)Output voltage 0 - 100% of supply voltageOutput frequency 0 - 590 Hz*Switching on output UnlimitedRamp times 1 - 3600 s* Dependent on power size.Torque characteristicsStarting torque (Constant torque) maximum 110% for 1 min.*Starting torque maximum 135% up to 0.5 s*Overload torque (Constant torque) maximum 110% for 1 min.**Percentage relates to the frequency converter's nominal torque.Cable lengths and cross sectionsMax. motor cable length, screened/armoured VLT® HVAC Drive: 150 mMax. motor cable length, unscreened/unarmoured VLT® HVAC Drive: 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 inputsProgrammable 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.General Specifications and ...
