Output Voltage Control (Output Vlt Ref) - GE AV-300i User Manual

N !
OTE In order to use the Catch on Fly function, it is necessary to set Lock Flux pos = Off.
Furthermore, in Magn ramp time it is possible to set the magnetizing current ramp time in seconds, which can be
used:
· To slow down the temporary magnetizing period and avoid a rotation of the motor shaft due to the stator-rotor
alignment.
· To speed up the magnetizing phase.

1.10.3 Output Voltage Control (Output Vlt Ref)

The Function allows the regulation of the flux in the constant power area where a voltage margin must be
available for the regulation. This value is usually equal to 2% of the maximum output voltage.
A higher value allows a faster response of the voltage regulator but with a lower amount of available voltage on
the output. A lower value allows a higher output voltage with a decrease of the dynamic performances.
The Outvlt lim src source allows to select the function control signal.
In the standard configuration the source is connected to Int Outvlt lim, internal value.
Via the Int Outvlt lim parameter, which can be set in the configurations, it is also possible to control the maximum
value of the output voltage and to state, therefore, the starting voltage of the discharge point (380V standard).
This value can not be higher than the one stated by Available Outvlt.
The available voltage margin is stated via the Dyn vlt margin parameter, which can be set in the configurations.
As for the normalized value see paragraph 1.1.3 Normalizations Signal.

The Function is active only in a Sensorless and Field oriented mode.
