BIT 4: VOLTAGE ENABLED
High voltage is applied to the drive when this bit is set to 1.
BIT 5: QUICK STOP
When reset, this bit indicates that the drive is reacting on a quick stop request. Bits 0, 1 and 2
of the statusword must be set to 1 to indicate that the drive is capable to regenerate. The
setting of the other bits indicates the status of the drive (e.g. the drive is performing a quick
stop as result of a reaction to a non-fatal fault. The fault bit is set as well as bits 0, 1 and 2).
BIT 7: WARNING
A drive warning is present if bit 7 is set. The cause means no error but a state that has to be
mentioned, e.g. temperature limit, job refused. The status of the drive does not change. The
cause of this warning may be found by reading the fault code parameter. The bit is set and
reset by the device.
If a fault on static brake occurs it is reported on bit7 (warning).
