P311
Speed controller I
(Speed controller I)
P
0 ... 800 % / ms
{ 20 }
I-component of the encoder (Integration component).
The integration component of the controller enables the 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
(Torque current controller P)
S P
0 ... 800 %
{ 200 }
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 entered in P312 and P313, then the torque current control is switched off. In
this case, only the motor model pre-control is used.

P314
Torque current controller limit
(Torque current controller limit)
S P
0 ... 400 V
{ 400 }
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.

P315
Field current controller P
(Field current controller P)
S P
0 ... 800 %
{ 200 }
Current controller for the field current. The higher the current controller parameters are set, the
more precisely the current setpoint is maintained. Excessively high values for P315 generally lead
to high frequency vibrations at low speeds. On the other hand, excessively high values in P316
generally produce low frequency vibrations across the whole speed range If the value "Zero" is
entered in P315 and P316, then the field current controller is switched off. In this case, only the
motor model pre-control is used.
