This word parameter indicates fault conditions in the Drive that CANNOT be configured as warnings. When a bit is set
to “1”, the corresponding condition in the Drive is true, otherwise the condition is false. Bit 0–3 are detected by hardware
and 4–15 are detected by software.
This word parameter indicates a fault condition which has been detected during power up or reset of the drive. Where
the bit is set to “1”, the corresponding condition in the Drive is true, otherwise the condition is false.
