Fault
The control card and the firmware (Flash Eprom) do
not match.
Please call customer service.

BR overload
Warning / fault
For the parameterized brake resistor, the drive
converter computes a temperature image. If the brake
resistor is controlled, the drive converter calculates
the assigned temperature. If a threshold is exceeded,
the drive converter signals a brake resistor overload
condition.
Causes outside of the device:
Only for the option W brake resistor:
The brake resistor which is being used has an
excessive ohmic value.
A brake resistor has not been connected.
The connected brake resistor is too low for the energy
which is fed-back into the DC link when braking.
Check the brake resistor.
Causes in the parameterization:
The down-ramp was set too fast.
An incorrect brake resistor was selected.
Only for an external programmable brake resistor:
The values for the resistance, continuous output
and/or thermal time constant were incorrectly
parameterized.
Check the down ramp in P0280.0X
In P0038 check whether the correct brake resistor was
selected.
Information regarding Standard: Every drive converter
output class is assigned a specific brake resistor.
Check the values in P0623 to P0625.
Maintain the max. braking duration and the required no-
load times to the next braking operation. The load
diagram in the instructions for the brake resistor option
can be used to calculate the braking and no-load times.
