74 ADL300 • Functions description and parameters list
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.

17.13 2300 Minimum speed OL rpm INT16 15 0 CALCI ERW __S
Setting of the minimum speed threshold in the sensorless vector control mode. Below this limit the sensorless regulator is
disabled.

17.15 2304 Speed filter OL ms FLOAT 5.0 0.1 20.0 ERWZ __S
Setting of the time constant for the estimated speed in sensorless vector 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.

17.16 2306 Flux observe gain OL FLOAT 500.0 10.0 5000.0 ERW __S
Flux observer gain in open-loop ux vector control mode.
In case at the low speed (<400 rpm) the oscillation is still present change the setting of this parameter at a lower value.
In case at the high speed (> 800 rpm) the oscillation is still present change the setting of parameter 2604 at a higher value.

17.18 2310 Flux weakening OL ENUM Disable 0 1 ERWZ __S
Enables or disables ux reduction in the open-loop ux vector control mode.
If set to Disable, the ux is not reduced when the speed of the motor exceeds the nominal speed. This results in loss of
control and instability.
This problem can be prevented by setting the parameter to Enable.
In the open-loop mode a ux value of less than the nominal speed of the motor is advantageous in terms of stability.
