Drive-Based Autotuning; Drive-Based Autotuning - Fast - Servotronix CDHD2S User Manual

Tuning
Initially use the Autotuning wizard to set the HD control loop parameters. Drive tuning
performed by the wizard is usually sufficient. However, you may need to manually tune control
parameters to optimize them for your specific application. Parameters can be viewed and modified
in the ServoStudio2 Position Loop - HD Controller screen.
Automatic and manual tuning use similar methods. During the autotuning, the movement
quality is measured and evaluated by the drive or software. During manual tuning, the quality of
movement is evaluated by the user. In both cases, modify the servo control parameters step by step
and select the values that deliver the best performance.
The Autotuning wizard can also be used to optimize drive parameters to produce the most
efficient transmission for a specific task or application. Setting and optimizing parameters via the
Autotuning wizard can be drive-based or PC-based:
If an electronic motor nameplate is detected at power-up (such as PRO2 and PRDH2
⚫
motors with sensAR magnetic encoders), or if the software is running offline,
ServoStudio2 will activate the drive-based autotuning wizard.
If no electronic motor nameplate is detected at power-up, ServoStudio2 will activate the
⚫
PC-based autotuning wizard.

8.3 Drive-based autotuning

If an electronic motor nameplate with a servo parameter bundle is detected at power-up (e.g.
PRO2 and PRHD2 motors with sensAR magnetic encoder), ServoStudio2 will activate the drive-
based autotuning wizard. This wizard is also activated if the software is run offline.
There are four possible common options for drive-based autotuning: Fast/Internal,
Fast/External, Advanced/Internal and Advanced/External.
Fast autotuning requires no user input, just activate each step.
⚫
Advanced autotuning requires user input.
⚫
Internal reference - Drive commands used for tuning are generated by the drive.
⚫
External reference - Drive commands used for tuning are generated by an external
⚫
controller (e.g. PLC).

8.3.1 Drive-based autotuning - fast

Fast autotuning requires no user input, just activate each step.
Fast autotuning consists of the following steps:
1. Select Fast/Internal or Fast/External.
2. Start autotuning.
3. Test results.
4. Save parameters.
