F42 Brake resistor overtemperature
F42 displayed.
Check logged
data in
fault history.
Is it possible to slow
down the process?
NOTE:
This fault code can appear only when internal
brake resistor and internal brake chopper is used.
Software
has detected too
high temperature
on internal
brake resistor.
Increase decceleration
time and start again.
Install properly
dimensioned, external
external brake resistor and
make parameter changes.
F42 again?
Wrong parameter
setting.
NO
NO
YES
Fault occurred due
to
wrong dimensioning
of brake resistor.
YES
YES
