Possible cause
Frequency converter fan does not
start.
NXS control unit can not control NXP
power unit and vice versa
Supplementary board exchanged.
Different power ratings.
Supplementary board added.
Drive with other power ratings added.

Unknown supplementary board or
unknown drive.
Overtemperature protection of IGBT
inverter has detected an increased
short-time overload current.
Overtemperature protection of internal
braking resistor has detected
too heavy braking.
Note deviating fault time data record.
