Diagnostics
With parameter 90.45 Motor feedback fault, you can select how the drive reacts when
it detects that the encoder signal is lost.
•
90.45 = 0 (Fault) – The drive generates a fault (7301 Motor speed feedback), and
the motor coasts to a stop.
•
90.45 = 1 (Warning) – The drive generates a warning (A7B0 Motor speed feedback)
and continues operation using estimated feedbacks.
If the drive generates this fault or warning:
