14.11.10 Dynamic braking
Overview
With the help of dynamic braking, the converter brakes the motor without causing an additional
temperature rise in the motor. An external braking resistor converts the braking energy of the
motor into heat.
Requirement
Converter with the number "0" at the 8th position of the Article number: 6SL4113-0…
Description of function
Figure14-190 Power ow during dynamic braking
The braking resistor converts the regenerative energy E generated when the motor brakes
into heat in a braking resistor.
