Autotune Wizard
The Autotune Wizard tunes the MicroFlex e190 for optimal performance with the
attached motor. This removes the need for manual fine-tuning of the system,
although in some critical applications this might be required.
Click Options... to configure optional autotuning parameters. Each Option shows
settings relevant to the adjacent test.
WARNING! The motor moves during autotuning. For safety it is advisable to
disconnect any load from the motor during initial autotuning. The motor can be
tuned with the load connected after the Commissioning Wizard has finished.
Autotune:
Click START to begin the auto-tuning process. Mint WorkBench takes measurements
from the motor and then performs small test moves.
For further information about tuning with the load attached, see Further tuning - with
load attached on page 101 .
Note: Even if you do not perform any further tuning or configuration, the STO function
must be tested; see Appendix: Safe Torque Off (STO) on page 187 .

Further tuning - no load attached
The Autotune Wizard calculates many parameters that allow the MicroFlex e190 to
provide good control of the motor. In some applications, these parameters need to be
fine-tuned to provide the exact response that you require.
1. Click the Fine-tuning icon in the Toolbox on the left of the screen.


The Fine-tuning window is displayed at the right of the screen. This already shows
some of the parameters that have been calculated by the Commissioning Wizard.


The main area of the Mint WorkBench window displays the capture window.
When further tuning tests are performed, it displays a graph representing the
response.
2. The Fine-tuning window has a number of tabs the bottom.


Click on the Current tab to fine tuning the current loop.

Click on the Velocity/ Position tab to fine tuning the velocity/position loop in
velocity / torque servo configuration.
