Frequency converter
max. 217 A | FC 71 SIEB & MEYER

The SIEB & MEYER frequency converter FC71 is used for the vector-controlled drive of asynchronous and synchronous motors. Speeds up to 150,000 rpm are reached. The vector control provides full torque at low speeds and allows back-magnetization of synchronous motors. Thus, also field-weakened motors can be accelerated up to their maximum speed.
In the machine tool the frequency converters reach positioning accuracies of 0.007°. Beside precise orientation during tool change this also allows interpolated working with feed axes, for example in threading applications.
