The new FR-A700 frequency inverters combine innovative functions and reliable technology with maximum power, economy and flexibility. The FR-A700 is particularly well suited for demanding applications like cranes and lifting gear, high-bay warehousing systems, extruders, centrifuges and winding machines.

Precision without encoders – Even without encoders the FR-A700 continuously calculates the optimum magnetic flux for every operating state. This now makes it possible to use inverters for many applications that were previously the exclusive domain of DC or closed-loop vector drives.

Ultra-precise speed and torque – When operated with an encoder, the FR-A700 drives impress with ultra-precise speeds across the entire control range (precision ±0.01 %) and extremely exact torque control (±10 % precision and ±5 % repeatability).

Autotuning – This new generation of inverters has an autotuning function that can obtain all the necessary specifications from the motor in less than a minute, even when the motor is not running.

Network capabilities – It comes with both a USB port and a connection for Modbus-RTU as standard equipment. Support is also available for Profibus, CC-Link, CANopen and the SSCNET III motion control network.
