Control Techniques SM-Resolver User Manual page 32

Any trip can be initiated by writing the relevant trip number to Pr 10.38. If any trips
shown as user trips are initiated the trip string is "txxx", where xxx is the trip number.
Trips can be reset after 1.0s if the cause of the trip has been rectified.
A full list of drive trips can be found in the Unidrive SP User Guide.

The SM-Resolver will only provide speed and position feedback when it is selected as
NOTE
the source of the drive speed/position feedback. Hence the SM-Resolver does not
function when the drive is operating in open-loop mode.

Fault description
No errors
Supply short circuit
The wire break detection looks at the SIN and COS signals and expects one signal
to be above the high threshold when the other is below the low threshold, or for
both signals to be in-between the threshold values. If the above conditions are not
satisfied, an error code 2 is produced.
The number of poles of the resolver is greater than 2, but is different to the number
of poles of the motor.
Solutions Module overtemperature.
