P310 Speed controller P P
Setting range
0 … 3200 %
Factory setting
{ 100 }
Description
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
Setting range
0 … 800 % / ms
Factory setting
{ 20 }
Description
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 curr. ctrl. P S P
Setting range
0 … 1000 %
Factory setting
{ 400 }
Description
Current controller for the torque current. The higher the current controller parameters
are set, the more precisely the current setpoint is maintained. At low frequencies,
excessively high values of P312 generally result in high frequency oscillations. On the
other hand, excessively high values of P313 usually cause low frequency oscillations
over the entire speed range
If the value "Zero" is set in P312 and P313, the torque current control is switched off.
In this case, only the lead time for the motor model is used.
P313 Torque curr. ctrl. I S P
Setting range
0 … 800 % / ms
Factory setting
{ 50 }
Description
I component of the torque current controller (see
P312
"Torque curr. ctrl. P").
