The servo inverter Sinamics V90 is intended for use with applications for dynamic motion and processing. The V90 already contains an integrated brake resistor. Nonetheless, some applications require an external brake resistor. KOCH offers safe brake resistors that are ideal for this purpose. They safely dissipate the generative electrical energy and thereby considerably improve the brake and delay capacities.
