Manual Tune
The Manual Tune function lets you manually improve motion performance by
adjusting system bandwidth, damping factor, and drive loop gains, filters, and
compensations via direct online control. Perform a manual tune when you are
online with a controller to get a real-time tune of an axis.
Manual Tune an Axis
If Autotune does not meet your system specifications, the manual tuning feature
lets you customize your tuning parameters. Perform a manual tune when you are
online with the controller to perform real-time adjustments to an axis. The
default Application Type is Basic, which implies manual tune modifies
proportional gains.
If you are not sure you need to Manual Tune, use this process:
• If the software calculation defaults are acceptable, tuning is complete.
• If the software calculation defaults are not acceptable, perform an
Autotune. If the Autotune results are acceptable, tuning is complete.
See Autotune Dialog Box on page 160
for details.
• If the Autotune results are not acceptable, perform a Manual Tune.
