1.8 General Technical DataProtection and features• Electronic thermal motor protection motor protection against overload.• Temperature monitoring of the heatsink ensures that the frequency converter trips in case of overtemperature.• The frequency converter is protected against short-circuits between motor terminals U, V, W.• If a motor phase is missing, the frequency converter trips and issues an alarm.• 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 too high.• The frequency converter is protected against earth faults on motor terminals U, V, W.Mains supply (L1/L, L2, L3/N)Supply voltage 200-240 V ±10%Supply voltage 380-480 V ±10%Supply frequency 50/60 HzMax. imbalance temporary between mains phases 3.0% of rated supply voltageTrue Power Factor ≥0.4 nominal at rated loadDisplacement Power Factor (cosφ) near unity (>0.98)Switching on input supply L1/L, L2, L3/N (power-ups) maximum 2 times/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, 240/480 Vmaximum.Motor output (U, V, W)Output voltage 0-100% of supply voltageOutput frequency 0-200 Hz (VVCplus), 0-400 Hz (u/f)Switching on output UnlimitedRamp times 0.05-3600 sCable lengths and cross sectionsMax. motor cable length, screened/armoured (EMC correct installation) 15 mMax. motor cable length, unscreened/unarmoured 50 mMax. cross section to motor, mains*Connection to load sharing/brake (M1, M2, M3) 6.3 mm insulated Faston PlugsMax. cross section to load sharing/brake (M4, M5) 16 mm2/6 AWGMaximum cross section to control terminals, rigid wire 1.5 mm2/16 AWG (2x0.75 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 1.7 Specifications for more information!Digital inputs (pulse/encoder inputs)Programmable digital inputs (pulse/encoder) 5 (1)Terminal number 18, 19, 27, 29, 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 kMax. pulse frequency at terminal 33 5000 HzMin. pulse frequency at terminal 33 20 HzQuick Guide VLT® Micro Drive Quick Guide16 MG02B702 - VLT® is a registered Danfoss trademark11
