Table 9: Piccolo Status Indications

Notes:

• Without latch mode:

The status indications are reset when the fault disappears.

• With latch mode:

The Short, Over Temperature and Commutation Failure status indications are reset when

the enable signal is temporarily removed from the enable input.

• Multiple faults:

Only the reading of the first fault is reliable. Additional faults add on to the status outputs

and the indication is therefore meaningless.
