Remarks
1 Operation enabled
Enable electronics and pulses, then ramp up to
active setpoint.
0 Operation inhibited
1 Fault active

1 Setpoint/actual value monitoring within tolerance
band
Actual value within a tolerance band; dynamic
overshoot or undershoot for t < t
e.g.
n = n ±
set
f = f ±, etc.,
set
t can be parameterized
max
0 Setpoint/actual value monitoring not within
tolerance band
1 Control requested
The PLC is requested to assume control. Condition
for applications with isochronous mode: Drive
synchronized with PLC system.
0 Local operation
Control only possible on device
