Brake chopper/braking resistor connection
The task of the brake chopper is to dissipate any unneeded energy in the event of
rapid changes in speed. If the set voltage threshold is exceeded, the external resistor
is switched on. For information relating to the chopper current and the recommended
braking resistance, please refer to the chapter "
INFORMATION
• The braking resistor is not included in the scope of delivery.
• The braking resistor is tested and designed according to the drive application.
(Observe maximum power loss!)
