Technology CPU
The data of the encoder used that is necessary to make the settings for the Technology CPU
is shown in the following section. Only the listed input values are evaluated for the respective
encoder.
The following settings refer to the input value for the fine resolution 0.
If a fine resolution 0 (standard) is set in the Technology CPU, this means a fine resolution of
2
11
Encoder parameters in SIMOTION are specified using parameters in the axis configuration
windows or using the configuration data in the expert list as
"TypeOfAxis.NumberOfEncoders.Encoder_1.xxx". The following assignments apply to the
axis configuration windows:
