Protection and Features• Electronic thermal motor protection against overload.• Temperature monitoring of the heatsink ensures that the frequency converter trips when the temperature reaches95 °C ± 5 °C. An overload temperature cannot be reset until the temperature of the heatsink is below 70 °C ± 5 °C(Guideline - these temperatures vary for different power sizes and enclosures). VLT® AQUA Drive has an autoderating function to prevent its heatsink reaching 95 °C.• The frequency converter is protected against short-circuits on motor terminals U, V, W.• If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuitvoltage is too low or high.• The frequency converter is protected against earth faults on motor terminals U, V, W.Mains supplySupply terminals (6-pulse) L1, L2, L3Supply terminals (12-pulse) L1-1, L2-1, L3-1, L1-2, L2-2, L3-2Supply voltage 380-480 V ±10%Supply voltage 525-600 V ±10%Supply voltage 525-690 V ±10%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 lowest rated supply voltage. Power-up and fulltorque cannot be expected at mains voltage lower than 10% below the lowest rated supply voltage.Supply frequency 50/60 Hz +4/-6%The frequency converter power supply is tested in accordance with IEC61000-4-28, 50 Hz +4/-6%.Max. imbalance temporary between mains phases 3.0% of rated supply voltageTrue Power Factor (λ) ≥ 0.9 nominal at rated loadDisplacement Power Factor (cosφ) near unity (> 0.98)Switching on input supply L1, L2, L3 (power-ups) ≥ enclosure type D, E, F 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, 480/600 Vmaximum.Motor output (U, V, W)Output voltage 0–100 % of supply voltageOutput frequency 0-590 HzSwitching on output UnlimitedRamp times 1–3600 sTorque characteristicsStarting torque (Constant torque) maximum 110% for 1 minute*Starting torque maximum 135% up to 0.5 s*Overload torque (Constant torque) maximum 110% for 1 minute**Percentage relates to nominal torque of VLT AQUA Drive.Selection VLT® AQUA Drive FC 202 Design GuideMG20Z102 - VLT® is a registered Danfoss trademark 473 3
