XPS-D Controller User Interface Manual
2.16 Stages – Tuning
2.16.1 Tuning – Auto-Scaling
Auto-scaling is only available with positioners that feature a direct drive motor such as
the XM, ILS-LM, IMS-LM or RGV100BL. To guarantee consistent performance of
these stages, it is strongly recommended to perform Auto-scaling once the load is
attached to the stage. During auto-scaling, the XPS controller measures the mass (inertia
for rotation stages) on the positioner and returns recommended values for the Scaling
Acceleration parameter.
Repeat Auto-scaling with any major change of the payload on the positioner. With no
major change of the payload, there is no need to redo Auto-scaling.
To perform Auto-scaling, do the following:
1. Select the main tab TUNING. Then select a positioner name. The following screen
appears:
2. Click “Kill” if not in “Not initialized state”, then click “Auto-scaling”. The stage
vibrates and an auto-scaling progress bar appears.
