5.4.3 Motor control modes
Most applications like fans, pumps, and conveyors are possible in V/f (Voltage/frequency) mode. If the applica-
tion requires more dynamic and speed assurance then the SLVC (Sensor less Vector Control) mode can be used.
1: P208:1 AC input voltage
2: P303:1 Base Voltage
5: P303:2 Base Frequency
6: P211:0 Maximum frequency
