Adjusting Gains Values for the Servo Axis 111
Adjusting Gains Values for the Servo Axis
The Adjust Gains dialog box is accessible only if the start-up (offline)
gain values and the working (online) gain values are identical.
Equalizing the Working and Set-up Gains Values
You must be online to set the working and the setup gain values equal to
each other. To set the values, do one of the following:
• On the Apply page of the Configure Axis Use dialog box, select
Upload or Download (depending upon the version of the axis use
configuration you want to use).
• On the General page of the Control Options dialog box, select
Download Axis/Drive. The current application program is
downloaded.
Adjusting Gains
You can use the Adjust Gains dialog box to:
• Make incremental changes to working gain values, start-up gain
values, or both.
• Start, stop, or kill the program, as needed, as you fine-tune the gain
values.
These digitally-set gain values provide software control over the servo
dynamics and allow the servo system to stabilize.

ATTENTION: The Up and Down buttons immediately
affect the control’s gains. Some gains values can cause
unpredictable motion. Keep clear of dangerous moving
machinery.
