Operating within an input range of 380 VDC to 480 VAC across a 50\/60 Hz frequency line, this unit converts line power into regulated output frequency spanning 0.1 to 599 Hz. Rated for a nominal output of 22 kW (30 hp) at 480 V, the assembly features an integrated EMC filter alongside a heavy-duty cooling heat sink to sustain maximum torque profiles under variable load conditions.\u003c\/p\u003e\n\u003ch3\u003e\nHardware Specifications\n\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cstrong\u003eParameter\u003c\/strong\u003e\n\u003c\/th\u003e\n\u003cth\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e\n\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nModel\n\u003c\/td\u003e\n\u003ctd\u003e\nATV71HD22N4\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nBrand\n\u003c\/td\u003e\n\u003ctd\u003e\nSchneider Electric\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nOrigin\n\u003c\/td\u003e\n\u003ctd\u003e\nFrance\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nWeight\n\u003c\/td\u003e\n\u003ctd\u003e\n21 kg\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nDimensions\n\u003c\/td\u003e\n\u003ctd\u003e\n230 mm x 420 mm x 236 mm\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nOperating Temp\n\u003c\/td\u003e\n\u003ctd\u003e\n-10 to 50 deg C (without derating)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nPower Consumption\n\u003c\/td\u003e\n\u003ctd\u003e\n22 kW (30 hp) output rating\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nInput Voltage Range\n\u003c\/td\u003e\n\u003ctd\u003e\n380...480 VAC (-15% to +10%), 3-phase\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nLine Current\n\u003c\/td\u003e\n\u003ctd\u003e\n42 A at 480 V \/ 50 A at 380 V\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nContinuous Output Current\n\u003c\/td\u003e\n\u003ctd\u003e\n40 A at 4 kHz \/ 460 V\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nMaximum Transient Current\n\u003c\/td\u003e\n\u003ctd\u003e\n72 A for 60 s \/ 79.2 A for 2 s\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nOutput Frequency Range\n\u003c\/td\u003e\n\u003ctd\u003e\n0.1...599 Hz\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nSwitching Frequency\n\u003c\/td\u003e\n\u003ctd\u003e\n1...16 kHz (4 kHz nominal)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nIngress Protection\n\u003c\/td\u003e\n\u003ctd\u003e\nIP20\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nAnalog Inputs\n\u003c\/td\u003e\n\u003ctd\u003e\n1x differential voltage (+\/-10 VDC), 1x current\/voltage (0-20 mA \/ 0-10 VDC)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nAnalog Outputs\n\u003c\/td\u003e\n\u003ctd\u003e\n1x software configurable (0-20 mA \/ 0-10 VDC)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nDiscrete Inputs\n\u003c\/td\u003e\n\u003ctd\u003e\n7x 24 VDC programmable (LI1...LI6, PWR safety input)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nRelay Outputs\n\u003c\/td\u003e\n\u003ctd\u003e\n2x configurable logic relays (R1A\/R1B\/R1C NO\/NC, R2A\/R2B NO)\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\nIntegrated Protocol\n\u003c\/td\u003e\n\u003ctd\u003e\nModbus RTU (RS 485), CANopen\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e\nBackplane Bus \u0026amp; Deterministic Communications\n\u003c\/h3\u003e\n\u003cp\u003eThe ATV71 drive architecture uses internal bus synchronization protocols to manage deterministic fieldbus exchanges and high-density I\/O expansion. When interfacing with industrial networks via optional communication adapters (such as Modbus TCP, EtherNet\/IP, or Profibus DP), the unit executes control commands while suppressing firmware flash compatibility errors. Internal signal routing ensures isolation between high-voltage power components and low-voltage control terminals, preventing cross-talk and field noise interference from compromising high-speed pulse feedback loops.\u003c\/p\u003e\n\u003ch3\u003e\nFrequently Asked Questions\n\u003c\/h3\u003e\n\u003cp\u003eQ: What are the torque limits and current specs for the PWR safety input terminal?\u003c\/p\u003e\n\u003cp\u003eA: The PWR safety terminal functions as a dedicated Safe Torque Off (STO) circuit operating at 24 VDC with an input impedance of 1500 Ohm.

Control logic terminals accept 2.5 mm2 (14 AWG) wiring tightened to 0.6 N.m.\u003c\/p\u003e\n\u003cp\u003eQ: Can the drive operate without current derating at high switching frequencies?\u003c\/p\u003e\n\u003cp\u003eA: Standard operation uses a nominal 4 kHz switching rate. The drive allows frequency adjustments between 1 and 16 kHz, but operation above 4 kHz requires applying an automated current derating factor to manage heat sink thermal dissipation.\u003c\/p\u003e\n\u003ch3\u003e\nField Installation Guidelines\n\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\nMount the drive in a vertical orientation within +\/- 10 degrees on a flat, non-combustible vertical support surface to ensure uninhibited natural convection across the heat sink cooling fins.\n\u003c\/li\u003e\n\u003cli\u003e\nMaintain clear ventilation paths surrounding the drive housing: ensure at least 100 mm of unobstructed space above and below the chassis for airflow exhaust.\n\u003c\/li\u003e\n\u003cli\u003e\nEnsure all motor leads consist of shielded cabling up to a maximum length of 100 m (or 200 m for unshielded cabling) to comply with integrated EMC filter limits and prevent high-frequency radiation.\n\u003c\/li\u003e\n\u003cli\u003e\nEstablish direct PE (Protective Earth) low-impedance grounding connections using copper conductors rated for at least 75 deg C.
