is used to determine another actual speed value of the motor using the terminal voltage at the motor,
the impressed current and the motor parameters.
You can configure the parameters required for calculating the Motor-EMK on the advanced
parameters tab.
Power stage
This menu ( Parameters/Device parameters/Power stage ) determines the behaviour of the power
stage.
You can select a clock frequency of 10 kHz or 20 kHz.
If the clock frequency is low, the motor emits a singing sound. If you want the motor to run as quietly as
possible, choose the 20 kHz clock frequency. In addition, the losses in the motor are slightly reduced at
a high clock frequency (on the other hand the losses in the DUET_FL servo positioning controller will
increase which is why the adjustable maximum current limits are slightly lower). The clock frequency
has practically no influence on the control behaviour. The default setting of the clock frequency of the
power stage is 10 kHz.
The settings can only be changed if the power stage is switched off. In addition, you have
to save the parameter set and reset the device to make the setting effective.
