A.10
This fault occurs if heat sink temperature <= -10° C for 2 seconds. In cases of
multiple Inverter Units, this fault is for the first Inverter Unit. This fault will also
come if thermistor is not connected or loosely.
It indicates that V phase current sensor has failed.
It indicates that W phase current sensor has failed.
This fault occurs if thermistor sensor is short.
This fault will come if thermostat is not connected or loosely.
This fault occurs if RUN did not turn OFF after engaging the external brake.
This fault occurs if the brake command and answer signal from the brake do
not match.
It indicates that current sensor has failed of respective U/V/W phase of
respective inverter unit. These faults applicable only for PCA-2049A parallel
interface board.
