Comments Notes on the SetPositionScale command (Code
• If the scale factor for scaling the position values is changed, then the application program's
calibration factor for calculating RTC
position values (in mm) (see
scaling. In addition, the jump and marking speed should be adjusted.
• The currently set scaling factor can be queried with Data = 053F
Note on the SetPosAcknowledgelevel command (Code
• The threshold value must be specified related to a 16-bit position range. This value is converted
by the RTC
cable reconverted by the XY2-100 converter).
• The default start behavior is for the scan system to set the threshold value to 0.28% of the full
position range after every power-up or reset (for iDRIVE
this corresponds to 0.28% of 2
face to 0.28% of 2
If other threshold values are desired, they must be separately set for each axis (Code
SCANLAB recommends setting only threshold values (Code
position range). Lower values can lead to frequent system safety shutdowns due to Position
Acknowledge time outs (set position not reached for an excessive time).

20-bit range, even in RTC
