47.23 Integral term Usd
Displays the integration terms of the control variable for the id controller.
47.24 Usq control output
Output value of the PI current controller.
47.25 Usd control output
Output value of the PI current controller.
47.26 Back-EMF feedforward
Displays the voltage set value from the BACK-EMF feedforward.
This results from the speed actual value (Z18.22–), the motor voltage constant ("Ke fac-
tor" Z107.20–) and the flux set value Z146.13–.
The exact correlation between the speed actual value and the EMF feed forward is shown
in adaption EMF feed forward (
ZFig. 173– on page 523)
47.27 U Alpha set value
Real part of the control variable for the current controller in stator frame coordinates.
47.28 U Beta set value
Imaginary part of the control variable for the current controller in stator frame coordinates.
47.29 Control value U
Modulation level of the IGBTs in Phase U. A value of 0 or 1 means full modulation.
47.30 Control value V
Modulation level of the IGBTs in Phase V. A value of 0 or 1 means full modulation.
