Example for internal braking resistor application
A 1FL2104-4AG... servomotor with low moment of inertia (with integrated holding brake)
with a mechanical system is fed from a SINAMICS S200 6SL5510‑1BB11‑0A□0. It is to be
braked from 3000 r/min to 600 r/min with a braking duty cycle as t
Moment of inertia of the servomotor 1FL2104-4AG... J
Moment of inertia of the driven mechanical system J = 4 ×10
