I55AE311F10V1100WS Lenze Variable Frequency Drives (VFD)

Lenze I55AE311F10V1100WS is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter within the Drives sub-range, designed for variable speed and frequency control with additional features including compact inverter DC-injection braking, brake management for brake control, S-ramps for smooth acceleration and deceleration, flying restart circuit, and a PID controller. It incorporates a built-in RFI filter, standard I.O. conformal coating, and supports Modbus TCP communication protocol. Protection functions cover overvoltage category, leakage current, earth fault resistance, and overtemperature of the motor. The rated current is specified as 28.2A for light-duty at 400Vac, 25.2A for light-duty at 480Vac, 23.5A for heavy-duty at 400Vac, and 21A for heavy-duty at 480Vac. It operates on a supply voltage of 400Vac / 480Vac, suitable for control cabinet or surface/wall mounting. The ambient air temperature for operation is capped at a maximum of 45°C at a switching frequency of 2kHz or 4kHz, and 40°C at a switching frequency of 8kHz or 16kHz, with a degree of protection rated at 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 features 1 x analog output (0-10Vdc; 0-20mA or 4-20mA), 5 x digital inputs (PNP/NPN logic), 1 x digital output (max. 100mA), and 2 x analog inputs (-10...+10Vdc; 0-20mA or 4-20mA). Rated active power is 15kW for light-duty and 11kW for heavy-duty, both at 400Vac / 480Vac, with rated power of 20HP for light-duty and 15HP for heavy-duty, at the same voltages.
