4.2.4 Brake resistor
Brake resistor 4- ][Funktion_Bremswiderstand_protego_D_01_24
When the servo motor is braked, energy is fed back to the servo ampli-
fier. This means that the capacitors in the intermediate circuit are
charged at higher voltages. The servo amplifier switches the brake resis-
tor to the intermediate circuit via the brake chopper. The brake resistor
converts the braking energy into heat.
The servo amplifier PMCprotego D has integrated brake resistors. Alter-
natively, external brake resistors may be connected.

Parameter setting
The thresholds for connecting the brake resistor to the mains voltage of
the servo amplifier are adjusted in the commissioning software.
Our Customer Support team can help you calculate the brake power you
will need for your plant.
