Chapter 9 Manual Tune
Axis Configuration Types
Manual Tune applies to Position Loop and Velocity Loop axis configurations.
Manual Tune is not available for any other axis configurations. If you change the
axis configuration to a value other than Position Loop or Velocity Loop while
Manual Tune is open, the contents of the Manual Tune expander becomes
disabled. This also applies to the Additional Tune functions.
Current Tuning Configuration
Manual Tune displays the current tuning configuration. All parameters on the
Manual Tuning dialog box are available while online.
When you adjust the sliders it tells you what gains you need to update. When
servo is on, the left area of the dialog box lights up. This gives you real manual
tuning capability. When you expand the Tuning Configuration, you are
reminded of the application type and coupling (loop response affects the system
damping) you selected. These values are governing the displayed values.
There are three Loop Response settings on the General dialog box.
TIP
In the RSLogix 5000 software, version 20 and later you can make edits when
online. In the RSLogix 5000 software, version 19 and earlier, changes can only
be made when online and the SERVO is enabled.
Loop Response relates to the
following values for System
Damping.
Low = 1.5
Medium = 1.0
High = 0.8
System Damping is for
setting the axis
Bandwidth and Error
Tolerance values.
