Description
Selects the motor speed feedback value used during
motor control.
Note: With a permanent magnet motor, make sure an
autophasing routine (see page 57) is performed using the
selected encoder. If necessary, set parameter
run requested requested to Autophasing
fresh autophasing routine.
A calculated speed estimate generated from the vector
control is used.
Actual speed measured by encoder 1. The encoder is set
up by the parameters in group 92 Encoder 1
Defines a filter time for motor speed feedback used for
control (90.01 Motor speed for control).
Motor speed filter time.
Selects how the drive reacts to loss of measured motor
feedback.
Drive trips on a 7301 Motor speed feedback. or
Encoder fault.
Drive generates a A7B0 Motor speed feedback
Encoder warning and continues operation using estimated
feedbacks.
Note: Before using this setting, test the stability of the
speed control loop with estimated feedback by running the
drive on estimated feedback (see 90.41 Motor feedback
selection).
Defines the speed feedback used by the vector motor
model.
The motor model uses the feedback selected by
Motor feedback selection.
The motor model uses the calculated speed estimate
(regardless of the setting of 90.41 Motor feedback
selection, which in this case only selects the source of the
feedback for the speed controller).
Enables/disables the motor encoder drift detection. When
drift is detected, fault 7301 Motor speed feedback
AUX code 4 Drift detected are set.
Drift detection is disabled.
Drift detection is enabled.
Configuration of encoder interface modules.
Validates any changed encoder interface module
parameters. This is needed for any parameter changes in
groups 90...93 to take effect.
After refreshing, the value reverts automatically to Done.
Notes:
• Permanent magnet motors only: The drive will perform
a fresh autophasing routine (see page 57) at next start
if the motor feedback encoder settings have been
changed.
• The parameter cannot be changed while the drive is
running.
