Interrelated parameterisations are partly shown on several device parameters (Px...) by the plug-in
with internal parameters (I...). Here, this is, for example, allocation and switching function of the refer-
ence switch.

2.3.7
Encoder interface
The working area contains parameter groups to display, configure and parameterise the encoder. The
configuration and parameterisation options are dependent on the properties of the applicable
encoder.
Parameters of the Configuration of encoder 1 (incremental) and Configuration of encoder 1 (BiSS-C)
groups can only be edited if a user-defined motor has been configured.
The configuration data can be automatically applied or read out in the following cases:
–
In offline configuration mode, the configuration data is automatically transferred to the project
upon selection of the motor.
–
The configuration data of motors and encoders with electronic rating plates are read out during
online configuration.

"Encoder selection of position control"
The encoder for the position controller is selected in this parameter group.
Additional information on encoder selection
è
Parameters of the actual value management.
"Feed constant"
The calculated feed constant for the encoder is displayed in this parameter group and adjusted to the
mechanics.
The parameter group is only visible if a linear axis is configured.
The feed constant is calculated as a fraction of the counter and denominator. A corresponding mes-
sage is displayed if the calculated value has to be rounded off.
"Encoder 1"
The encoder at encoder interface 1 is displayed and configured in this parameter group. This encoder
is the motor encoder.
When using Festo motors, encoder interface 1 does not need to be configured.
Additional information about encoder parameters
è
Encoder parameters and diagnostic messages.
"Configuration of encoder 1 (incremental)"
The encoder at encoder interface 1 is specially configured in this parameter group if it is an increment-
al encoder.
Additional information about encoder parameters for incremental encoders
è
Parameters of digital incremental encoders (A, B and N signals).
