Manual mode
This mode is used on test stands for which manual control is desired. I
ds,ref
is entered manually via
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
s
is aligned to the q-axis.
