I55AE411F1AV11000S Lenze Variable Frequency Drives (VFD)

Lenze I55AE411F1AV11000S is a variable speed/frequency drive (VSD/VFD) and inverter within the Drives sub-range, designed for variable speed and frequency control, compact inverter functionality, DC-injection braking, brake management, S-ramps for smooth acceleration and deceleration, flying restart circuit, and PID controller operations. It features a built-in RFI filter, safe torque off (STO) safety standard, I.O. conformal coating, and has dimensions of H685mm x W258mm x D304mm. This model does not include a communication interface but offers protection functions against overvoltage, leakage current, earth fault resistance, and overtemperature of the motor. It supports rated currents of 254A and 216A for light-duty at 400Vac and 480Vac respectively, and 212A and 180A for heavy-duty at the same voltages. The supply voltage is rated for 400Vac / 480Vac, with mounting options for control cabinet or surface/wall mounting. The operational ambient air temperature ranges up to 45°C at a switching frequency of 2kHz or 4kHz, and up to 40°C at 8kHz or 16kHz, with a degree of protection of IP20. It operates on a 3-phase network (3P / 3AC) with a network frequency of 45-65 Hz (input) and 0-599 Hz (output). The device includes 1 analog output, 5 digital inputs with optional uses for two of them, 1 digital output, and 2 analog inputs with optional voltage or current input functionality. The rated active power is 132kW for light-duty and 110kW for heavy-duty, with corresponding rated power of 180HP and 150HP for 400-480Vac operations.
