The control method for the motor is defined with this parameter. The following constraints must be
observed: In comparison with the
setting "0", the setting "2" enables somewhat higher dynamics
and control precision, however it requires greater effort for parameterisation. In contrast, the
setting "1" operates with speed feedback from an encoder and therefore enables the highest
possible quality of speed control and dynamics.
0 =
Off (VFC open -loop) 1)
Speed control without encoder feedback
1 =
On (CFC closed-loop) 2)
Speed control with encoder feedback
2 =
Obs (CFC open-loop)
Speed control without encoder feedback
NOTE:
Commissioning information ( Abschnitt 4.2 "Selecting the operating mode for motor control").
1)
Corresponds to the previous setting "OFF"
2)
Corresponds to the previous setting "ON"

Rotary encoder res.
(Rotary encoder resolution)
0 ... 17
{ 6 }
Input of the pulse-count per rotation of the connected encoder.
If the encoder rotation direction is not the same as the FI, (depending on installation and wiring),
this can be compensated for by selecting the corresponding negative pulse numbers 8...16.
0 = 500 pulses
1 = 512 pulses
2 = 1000 pulses
3 = 1024 pulses
4 = 2000 pulses
5 = 2048 pulses
6 = 4096 pulses
7 = 5000 pulses
8 = -500 pulses
9 = -512 pulses
10 = -1000 pulses
11 = -1024 pulses
12 = -2000 pulses
13 = -2048 pulses
14 = -4096 pulses
15 = -5000 pulses
16 = -8192 pulses
17 = 8192 pulses
NOTE:
(P301) is also significant for position control via incremental encoders. If an incremental encoder
is used for positioning (P604=1), the setting of the pulse number is made here.

Speed controller P
(Speed controller P)
P
0 ... 3200 %
{ 100 }
P-component of the speed 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.

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).
