Adjusting Resolution
(Original Document)
At a Glance
This adjustment is used to compensate for error resulting firstly from imprecise entry of configuration parameter values, and secondly from imperfections in the kinematics string.

Adjustment Procedure
Perform the following operations on the TSX CAY Debug screen:
Step
Action
1
Select Manual mode
2
Create a manual reference point if the encoder is of incremental type
3
Choose Theoretical distance as the value to run which corresponds to the greatest possible range of movement: position 1 and enter this value into the Param field (e.g. 300,000 microns)
4
Give the Inc- or Inc+ command depending on the direction of movement
5
Measure, with a sufficiently precise external device, the distance actually covered by the moving part (Observed distance)
6
Change to measurement mode DRV_OFF
Carry out the following operations from the Adjustment screen:
Step
Action
7
Press the Correction button, which displays the following dialog box:
  • Enter the distance to be covered in the Theoretical distance field. For example: 300,000 microns
  • Enter the distance done in the Observed distance field. For example: 293,000 microns
8
Press OK to activate the automatic resolution calculations. The new Distance and No. of pulses values are then re-calculated.
9
Repeat steps 2, 3, 4 and 5. If the distance measured reveals a deviation below requirements, then adjustment is finished. If this is not the case, carry out a new correction (steps 7 and 8).
NOTE: If you modify the Initial resolution and VMAX parameter values after adjusting the resolution, it is mandatory to resume the adjustment.
In general, modifying any configuration in offline mode means that the resolution must be re-adjusted in online mode.
