18.7.1
Inverter/feedback combination not possible
18.7.2
No feedback selected
18.7.3
Feedback system is not checked
Note!
The operation of the feedback system on the selected inverter is not possible.
Cause
Effects
Possible remedies
The feedback system selected cannot
be connected to the inverter.
Servo inverters cannot be operated
without feedback.
Use a different feedback system.
• If the feedback is not to be evalu-
ated by the inverter (e. g. feed-
back for slave drive), this conflict
can be ignored (not in the case of
servo inverters).
• Convert the output signal of the
feedback system into a suitable
signal.
Note!
The inverter requires a speed feedback for the control process selected.
Cause
Effects
Possible remedies
A motor without feedback was se-
lected, although the inverter requires
a feedback system for the motor con-
trol.
Possibly the inverter cannot be oper-
ated.
Select the "Feedback" option in the
dimensioning step "Structure of the
drive axis/mechanical".
Note!
Checking the inverter-encoder evaluation is not possible. Check manually whether the inverter is able to
evaluate the feedback system of the motor.
Cause
Effects
Possible remedies
The user motors are not provided
with detailed information on the
feedback system.
Checking the inverter-encoder evalu-
ation is not possible in DSD.
Check the inverter-encoder evalua-
tion manually.
