Sizing the external braking resistor
NOTICE
The selection of the external braking resistor is the responsibility of the machine builder
or plant engineer.
Whether and which external braking resistor is necessary depends on the circumstances of the
machine in which this component is to be installed.
►
Changes or modifications to the product are not permitted without the prior written consent of
Nanotec.
►
Contact Nanotec if you wish help selecting the external braking resistor or a specifc
customization of the product.
The value of the overall braking resistor (R
b
) depends on the maximum needed power (P
max
) of your
application and the desired switching threshold of the brake chopper (U
on
):

The value of the overall braking resistor results from the internal (4.7 Ohm) and the external resistor you
select. The external braking resistor is connected in parallel to the internal.
NOTICE
When selecting the external braking reistor, make sure that the permissible current of 40 A is not
exceeded (see
Electrical properties and technical data
). Following minimum values reult depending on
the operating voltage:
