B.1.3 Dynamic braking module
Article number: 6SL3201-2AD20-8VA0
Note
This module is applicable for frame sizes AA to C only.
Functionality
The dynamic braking module is typically used in applications in which dynamic motor
behavior is required at different speed or continuous direction changes, for example, for
conveyor drives or hoisting gear.
Dynamic braking converts the regenerative energy, which is released when the motor
brakes, into heat. Dynamic braking activity is limited by the duty cycle selected with the
control knob.
Mounting orientation
The dynamic braking module must be installed in the orientation as shown in the following
diagram. That is, the open slots must always point directly upwards to ensure adequate
cooling.
