I55AE411F10V11003S Lenze Variable Frequency Drives (VFD)

Lenze I55AE411F10V11003S is a variable speed/frequency drive (VSD/VFD) and inverter within the Drives sub-range, designed for compact inverter applications with DC-injection braking and brake management for brake control. It features S-ramps for smooth acceleration and deceleration, a flying restart circuit, and a PID controller. The design includes a built-in RFI filter, standard I.O., and conformal coating. Its dimensions are H685mm x W258mm x D304mm, and it supports the Modbus RTU communication protocol. Protection functions cover overvoltage category, leakage current, earth fault resistance, and overtemperature of the motor. The rated current varies with duty and voltage: 254A (light-duty; 400Vac), 216A (light-duty; 480Vac), 212A (heavy-duty; 400Vac), and 180A (heavy-duty; 480Vac). It operates on a supply voltage of 400Vac / 480Vac and can be mounted in a control cabinet or on a surface/wall. The ambient air temperature for operation is max. 45°C (at a switching frequency of 2kHz or 4kHz) and max. 40°C (at a switching frequency of 8kHz or 16kHz), with a degree of protection of IP20. It is designed for a 3-phase network (3P / 3AC) with a network frequency of 45-65 Hz (input) and 0-599 Hz (output). The unit includes 1 x analog output (0-10Vdc; 0-20mA or 4-20mA), multiple digital inputs with flexible functionality, 1 x digital output (max. 100mA), and 2 x analog inputs (-10...+10Vdc; 0-20mA or 4-20mA) with optional usage. The rated active power is 132kW (light-duty; 400-480Vac) and 110kW (heavy-duty; 400-480Vac), with rated power of 180HP (light-duty; 400-480Vac) and 150HP (heavy-duty; 400-480Vac).
