Avoiding unwanted axis movements
Automatic servo tuning is based on the analysis of measurements. These measurements
require the axis to move.
Carefully ensure that all axes are in a safe position and no collisions will occur during the
traversing motion that is required.
Number of measurements
For tuning purposes, the following measurements are taken with the speed controller:
Speed controlled system:
● Overall bandwidth: Preliminary measurement in both directions
● Overall bandwidth: Measurement in both directions
● Reduced bandwidth: Preliminary measurement in both directions
● Reduced bandwidth: Measurement in both directions
Mechanical system motor to DMS:
● Measurement in both directions
Tuning the X axis
Procedure:
1. Softkey "Options >", to select options when performing the measurements.
2. Softkey "Select strategy >", to select a strategy: Default setting 102, 203, 303.
3. Check that the tuning objective "Moderate responsiveness" is selected
