The quality of the control behaviour is set via the Vp-gain
factor
CO77 and the adjustment time Tn C078.
Therefore the field frequency is reduced with a
reduction
of the
torque setpoint,
until
the ratio between
Speed
and torque is stable.
If
the
,torque
setpoint
is increased, the field frequency increases.
Here, the field frequency input via terminal 8 or via the digital
frequency input or via
code
CO46 is used to limit the maximum field
frequency.
