5.2.4 Control parameter
In combination with an HTL incremental encoder, a closed speed control loop can be set up using
digital inputs 2 and 3 of the VFD.
Alternatively, the incremental encoder signal can also be used in another way. In order to do this,
select the required function in parameter P325.
In order to make this parameter visible, set the supervisor parameter P003 to 2 or 3.

The control method for the motor is defined with this parameter. The following constraints must be
observed: In comparison with the "0" setting, the "2" setting enables somewhat higher dynamics
and control precision but it requires greater parameterization effort. In contrast, the "1" setting
operates with speed feedback from an encoder and therefore enables the highest possible quality
of speed control and dynamics.

Input of the pulse number per revolution of the connected incremental encoder.
If the encoder rotation direction is not the same as that of the VFD (depending on installation and
wiring), this can be compensated for by selecting the corresponding negative pulse numbers
8...16 or 19.
