Table 10: Cymbal 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.
