(OFF3 inactive)
6 Switching on inhibited active

Explanation
1 Ready for switching on
Power supply on, electronics initialized, line contactor
released if necessary, pulses inhibited
0 Not ready for switching on
1 Ready for operation
Line voltage applied, i.e. line contactor closed (if
present), field being built up
0 Not ready for operation
Reason: No ON command has been issued.
1 Operation enabled
Enable electronics and pulses, then ramp up to active
setpoint
0 Operation disabled
1 Fault active
The drive is faulty and, therefore, out of service. The
drive switches to "switching on inhibited" once the fault
has been acknowledged and the cause has been
remedied. The active faults are stored in the fault buffer.
0 No fault active
There are no faults in the fault buffer.
1 Coasting down (OFF2) not active
0 Coasting down active (OFF2)
An OFF2 command is active.
1 Quick stop (OFF3) not active
0 Quick stop active (OFF3)
An OFF3 command is active.
1 Switching on inhibited
Switching back on is only possible by means of OFF1
and then ON.
0 No switching on inhibited
Switching on is possible.
1 Alarm active
The drive is operational again. No acknowledgement
necessary.
The active alarms are stored in the alarm buffer.
0 No alarm active
No alarms in the alarm buffer.
1 Setpoint/actual value monitoring in tolerance band
Actual value within tolerance band; dynamic overshoot
or undershoot permitted for t < tmax, tmax can be
parameterized. See FP8020 and FP2534
0 Setpoint/actual value monitoring not within tolerance
band
