5.1.4 Speed control
P300 Control method P
Setting range
0 … 2
Factory setting
{ 0 }
Description
The control method for the motor is defined with this parameter. The following
constraints must be observed: In comparison with setting {0}, setting {2} enables
higher dynamics and control precision, however it requires greater effort for
parameterisation. Setting {1} operates with speed feedback from an encoder and
therefore enables the highest possible quality of speed control and dynamics.

Description
"Encoder resolution". Input of the pulse count per rotation of the connected encoder.
If the direction of rotation of the encoder is not the same as the FI, (depending on
installation and wiring), this can be taken into account by selecting the corresponding
negative pulse numbers.
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 (see supplementary POSICON manual).
