Product details

Where 1FK7043-4CH71-1RG0 sits on the 1FK7 shelf

Servo motors in this class feed the position loop of a Siemens drive (SINAMICS family controller pairing), where the rotor inertia and the high-dynamic winding design determine how fast the axis can accelerate before the drive trips on overcurrent or following error.
