19.12 2292 Voltage margin perc FLOAT 5.0 0.0 10.0 ERWS F_S
Setting of the voltage regulation margin according to the available voltage. In case of a Voltage base setting
close to or equal to the actual mains value, Voltage margin represents the margin allowable by the voltage
regulation to perform rapid current variations when load steps are suddenly applied.
A value of 5% allows a very fast response to load steps but with a loss of output voltage and thus power output
(reduced power output).
The minimum value (1%) allows a maximum output voltage (around 98%) of the mains voltage to be achieved
but with loss of quality of the dynamic response.

19.13 2300 Minimum speed OL rpm INT16 30 0 CALCI ERW __S
Setting of the minimum speed threshold in the Flux vector OL control mode. Below this limit the sensorless
regulator is disabled.

19.14 2302 Min speed delay OL ms UINT16 200 0 5000 ERW __S
Setting of the delay for disabling the sensorless regulator.

19.15 2304 Speed filter OL ms FLOAT 5.0 0.1 20.0 ERWZ __S
Setting of the time constant for the estimated speed in Flux vector OL mode. By increasing this parameter it
is possible to reduce the level of disturbance of the estimated speed, but the speed control dynamics are also
lowered.

19.16 2306 Flux observ gainH OL FLOAT 250.0 10.0 5000.0 ERW __S
Gain value of the Flux observer at the high frequency/speed (Flux vector OL control mode).
Note! Frequency value set in IPA2322 must be higher than the value set in IPA2324 (without sign). All the Flux gain values between the
two frequency are obtained through linear interpolation.
The default gain value set at the low frequncy (IPA 2316) should guarantee smooth operation for all motor power sizes.
For any possible issues during the speed starting phase is possible to improve the response of the motor by changing the value of
the gain. Normally high gain values guarantee more stability, but could lead to errors on estimation Torque value.
The gain at high frequency (IPA 2306) must be changed if speed fluctuations at high rpm are shown.
By increasing the gain value it is possible to get better performance, however, too high values could lead to instability of the mo-
tor speed control.
