8.4.4.9 Slip controller
In case of V/f characterisc control with feedback (VFC closed loop), the slip is calculated and
injected by the slip controller. The default seng of the slip controller provides robustness
and moderate dynamics.
Precondions
In 0x2C00 (P300.00), the motor control type "V/f characterisc control (VFC closed loop) [7]"
is selected and congured. For details, see chapter "V/f characterisc control (VFC closed
loop)". ^ 172
Details
•
The slip controller is designed as PI controller.
•
In order to improve the response to setpoint changes, the setpoint speed of setpoint fre-
quency is added as feedforward control value to the output (correcng variable) of the slip
controller.
•
With the seng 0x2B14:003 = 0 Hz, the slip controller is deacvated.
