) Note!
If one of the inputs is set to HIGH, it is not possible that a LOW−HIGH edge occurs
at the resulting signal.
3.5.26.6 Controller state
The status is binary coded via the outputs DCTRL−STAT*x. These outputs are connected with the
STAT function block inside the device.
The status can be evaluated via the status word C0150, CAN status word, and AIF status word.
STAT*8 STAT*4 STAT*2 STAT*1 Action of the controller

0 0 0 1 Switch−on inhibit (LOCK MODE), restart protection is active C0142
0 0 1 1 Drive is inhibited
0 1 1 0 Controller enabled
0 1 1 1 The activation of a monitoring function resulted in a "message"
1 0 0 0 The activation of a monitoring function resulted in a "trip"
1 0 1 0 The activation of a monitoring function resulted in a "FAIL−QSP"
3.5.26.7 Speed threshold n

=0rpm
The standstill message (DCTRL−NACT=1) is set if the actual speed (MCTRL−NACT) is lower than the
threshold set in C0019.
The standstill message (DCTRL−NACT=0) is cancelled if the actual speed (MCTRL−NACT) exceeds
a threshold from C0019 plus hysteresis. The amount of hysteresis corresponds to 1 % of the max.

from C0011.
) Note!
The hysteresis provides for a stable standstill signal, even in the case of a jittering
actual speed value. The hysteresis only has an effect during start−up and is not
active during a stop process.
