LDU ERROR CODES
Lithium
Signal2 Offset Out of Range:
The adapted offset is too high or too
low.
SIN COS Sensor Not Connected:
Check that the unit circle vector is
constant. The system will detect a
broken signal even if the motor is not
rotating.
Speed Error:
The speed calculated from the
sensor signals is not valid.
High Side Output Low:
The high side output has been
detected to be low. This indicates a
short circuit to B-.
High Side Output High:
The high side output has been
detected to be high. This indicates a
short circuit to B+.
High Side Output Not Connected:
The system detected that nothing is
connected to the high side output.
High Side Switch SHC Supervision:
A short circuit of the high side switch
controlled by the supervision CPU
was detected. This indicates a
hardware failure.
High Side Switch SHC Main:
A short circuit of the high side switch
controlled by the main CPU was
detected. This indicates a hardware
failure.
High Side Plausibility Error:
An internal high side failure was
detected. This indicates that the high
side output is not producing the
expected voltage.
Signal1 Amplitude Out of Range:
The adapted amplitude is too high or
too low.
