7-26 Setting Up Your SLC Servo Module
Configuration Parameters This section provides information to help you set discrete and
floating-point parameters for the SLC Servo Module. These parameters
are grouped according to their function:
•
Feedback parameters
•
Servo loop parameters
•
Motion parameters
•
Axis parameters
•
Homing parameters
•
System parameters
You can determine these parameters by using the integration
procedure described in the Setting Up Your SLC Servo Module chapter.
Feedback Parameters
Feedback parameters define the position feedback sent to the SLC
Servo Module. This position feedback is for the axis controlled by the
SLC Servo Module. Use Figure 7.3 and the following table to see how
feedback parameters work with the servo loop parameters.
Figure 7.3 How Feedback Parameters Work with Servo Loop Parameters
The following table provides the name, file location, and a brief
description of the Feedback parameters. For more detailed
information see Appendix A of this manual.
