In addition to the angle encoder configuration, this menu can also be used to perform basic
configurations concerning the control system.
 Commutation: Block commutation or sine commutation.
 Speed controller recirculation: Encoder or Motor-EMK (separately for P-component and
I-component).
If a motor with analog Hall sensors is used for the commutation, the automatic adjustment of the
encoder signals can be started by pressing the button
Automatic encoder optimization . The
DUET_FL determines the optimum offset values and the amplitude values of the SIN and COS track
signals and saves them. This reduces the tolerances of the encoder and of the encoder evaluation in
the DUET_FL and improves the running behavior.
Caution! During the adjustment, the shaft automatically starts to move for approximately
60 seconds.
Recirculation through the Motor-EMK (electromotive force of the motor) has a positive effect on the
running behaviour of the motor if encoders with a poor resolution (e.g. Six-Step Hall encoders) or a low
level of accuracy are used. In order to use the recirculation through the Motor-EMK, other electrical
parameters of the motor have to be entered in the menu
Options/Device parameters/Motor data
(see chapter 3.1.1 Motor data ).
Be careful when activating the recirculation through the Motor-EMK!
The actual speed of the motor may deviate significantly from the setpoint if the function
and the motor data are not properly configured. The tolerances of the magnets and the
windings of the motors in the series also affect the result.
A good compromise between smooth running and a good stationary accuracy can be
realized by setting only the P-component of the speed controller to EMK.
3.1.1 Motor data
This menu must be used if the motor could not be identified with the help of the motor list.
