10.7.6.8 Flying restart controller
For a quick commissioning, the calculaons and sengs are made automacally during the
motor calibraon.
Precondions
The ying restart controller is only eecve in the following motor control types:
•
V/f characterisc control (VFC open loop)
•
Sensorless control (SL PSM)
•
Sensorless vector control (SLVC)
Details
The following parameter is only relevant for the ying restart circuit if an asynchronous motor
is controlled. In case of a sensorless control of a synchronous motor (SL-PSM) the parameter
has no meaning.
Parameter
Address Name / seng range / [default seng] Info

1 ... [5911]* ... 60000 ms
* Default seng depending on the size.
Integraon me for controlling the ying restart circuit.
10.7.6.9 SLVC controller
For a quick commissioning, the calculaons and sengs are made automacally during the
motor calibraon.
Precondions
The SLVC controller is only eecve in the motor control type "Sensorless vector control
(SLVC)".
Parameter

0x2B40:001 Gain
0.0000 ... [0.2686]* ... 1000.0000 Hz/A
* Default seng depending on the size.
Gain of the SLVC-Q controller.

1.0 ... [2.3]* ... 2000.0 ms
* Default seng depending on the size.
Reset me of the SLVC-Q controller.
10.7.6.10 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 for asynchro-
nous motor (VFC closed loop)". ^ 192
Details
•
The slip controller is designed as a PI controller.
•
In order to improve the response to setpoint changes, the setpoint speed or setpoint fre-
quency is added as a 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.
Parameter
