P310 Speed controller P P
Factory setting { 100 }
P-component of the encoder (proportional amplification).
Amplification factor, by which the speed difference between the setpoint and actual
frequency is multiplied. A value of 100 % means that a speed difference of 10 %
produces a setpoint of 10 %. Values that are too high can cause the output speed to
oscillate.
P311 Speed controller I P
Factory setting { 20 }
I-component of the encoder (Integration component).
The integration component of the controller enables complete elimination of any
control deviation. The value indicates how large the setpoint change is per ms. Values
that are too small cause the controller to slow down (reset time is too long).
P312 Torque current controller P S P
Description Current controller for the torque current. The higher the current controller parameters
are set, the more precisely the current setpoint is maintained. Excessively high values
in P312 generally lead to high-frequency oscillations at low speeds; on the other hand,
excessively high values in P313 generally produce low frequency oscillations across
the whole speed range.
If the value "Zero" is set in P312 and P313, the torque current control is switched off.
In this case, only the motor model lead time is used.
P313 Torque current controller I S P
0 … 800 % / ms
I component of the torque current controller (see P312 "Torque current controler P").
P314 Limit of torque current control S P
Setting range 0 … 400 V
Limit of torque current control
". Determines the maximum voltage increase of the
torque current controller. The higher the value, the greater the maximum effect that
can be exercised by the torque current controller. Excessive values in P314 can
specifically lead to instability during transition to the field weakening zone (see P320).
The values for P314 and P317 should always be set roughly the same, so that the
field and torque current controllers are balanced.
