The external braking resistor must
be
parameterized
via the firm-
ware to protect the drive
controller and the braking resistor against
overload.
See also Parameter Description of the firmware used:
"P-0-0860, Converter configuration"
and
"P-0-0858, Data of external braking resistor"
The drive
controller monitors the operating data of the external
braking resistor against the data
in
"P-0-0858, Data of external
braking resistor". Select braking resistors with a performance that
corresponds to the parameterized
values or more powerful braking
resistors.
