Description
Selects the source of motor speed and motor position
used as feedbacks for speed control and motor model.
A calculated speed estimate
Actual speed measured by encoder 1.
control.
Motor speed filter time.
Selects how the drive reacts to loss of measured motor
feedback.
Drive trips on a 7301 Motor speed feedback fault.
Drive generates a A7B0 Motor speed feedback 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 sel).
Defines the speed feedback used for motor control.
The motor model uses the feedback selected by 90.41
Motor feedback sel.
The motor model uses the calculated speed estimate
(regardless of the setting of 90.41 Motor feedback sel,
which in this case only selects the source of feedback for
the speed controller).
Enables motor encoder drift detection
Does not generate an error if encoder drift is detected.
Generates fault 7301 Motor speed feedback if encoder
drift is detected.
Description
Validates any changed encoder interface module
parameters. This is needed for any parameter changes
in groups 90...92 to take effect. After refreshing, the
value reverts automatically to Done.
Note: The parameter cannot be changed while the drive
is running.
Refreshing done.
