Table 9-3 Menu 3 Regen parameter descriptions
Figure 9-2 Current trimming state diagram
The power (Pr 5.03) and the reactive power are the power or VAR's respectively that flow from the supply to the drive. Therefore when this parameter
is positive the phase current flowing from the supply to the drive contains a component that lags the respective phase voltage, and when this
parameter is negative the phase current contains a component which leads the respective phase voltage at the drive terminals.
