The OMRON / Yaskawa CIMR-F7Z4018 Varispeed F7 Inverter is a 400V class AC drive delivering 18.5 kW maximum motor capacity with 40A rated output current. Built on current vector control architecture, it provides multiple control methods including open-loop current vector, full flux vector, torque, and PID control for demanding industrial motion applications. The unit features precision torque limit functionality, static autotuning, and energy-saving design. Network-ready with DeviceNet, Profibus, CANOpen, and RS485 Modbus support, it integrates directly into automated control systems. Rated for 150 Hz output in heavy-duty constant-torque service and 400 Hz in variable-torque modes. Protection includes 150% overload capacity (1 minute), 200% overcurrent shutdown, and dual-threshold overvoltage/undervoltage monitoring on the DC bus. Enclosed wall-mounted design meets IEC IP20 and NEMA Type 1 specifications. CE, UL, and c-UL certified.
