Ch.1
Voltage boost It increases the output voltage with low frequencies in order
to compensate the voltage drop on the stator. It avoids the
torque loss with a low output frequency.
Slip comp It compensates the speed change due to the load increase
considering the slip value.
Slip comp filter Filter on the slip compensation. It avoids oscillations due to a
step-load application (non-gradual).
Antioscill gain It allows to damp the current oscillations between the motor
and the DC link, which could be developed in the middle
range of the rated speed.
V/f ILim P gain Proportional gain of the pseudo-regulator
V/f ILim I gain Integral gain of the pseudo-regulator
1.4.3.2 Energy Saving (V/f Save Energy)
The function allows to reduce the motor Flux in order to reduce the losses.
As a consequence it is possible to obtain an energy saving when the load requires a reduced torque as compared
to the rated one (save energy).
Through the input
sources it is possible to select the origin of the save energy command signal and of the signal
stating the flux level.
The sources are:
-SE cmd src save energy command source
-SE flx level src source of the flux level value during the save energy
In the
configurations it is possible to set via Int SE flx level an internal percentage value stating the flux level and
via SE flx ramp time a ramp time on the level.
