Monitors voltage in the motor.Voltage control80
See section Motor voltage control.
Selected / unit16Defines the source for the Energy optimization enable
signal.
Energy optimization

80.01
The function automatically adjusts motor flux reference
to optimize the motor current considering the actual
mechanical load conditions.
Note: If Energy optimization is enabled, the U/F curve
settings has no effect.

Defines the source for the U/F curve enable signal.
When this parameter is enabled, the function will
control motor flux reference based on user settings
U/F curve enable80.10
with parameters 80.11 Frequency point 1...80.18
Frequency point 8. The requested change in voltage
reference is internally converted to motor flux reference
correction at a corresponding frequency point. The
effect of applied settings can be monitored through
signals 80.80 Flux correction and 80.81 Flux reference.
