NXGPro+ Control Description
4.7 Control Modes
• I
• Drive output PF < 1
• Motor PF (rotor reference) = 1
• Auto PF is on
Manual mode
This mode is used on test stands for which manual control is desired. I
parameter Output Ids (2982). The value entered can be positive or negative 100% of the motor
current rating. The magnitude is prevented from becoming less than 1% to prevent instability. V
is aligned to the q-axis.
The figures below show the vector diagrams for manual mode and manual network mode with
positive I
