List of operating parameters
P1 Unit of measurement 1)
Display in millimeters mm
Display in inches inch
P3.1 to P3.3 Radius/diameter display 1)
Display position value as radius RADIUS DISPLAY X
Display position value as diameter DIAM. DISPLAY X
P11 Activate scaling factor 1)
Scaling factor active SCALING ON
Not active SCALING OFF
P12.1 to P12.3 Enter scaling factor 1)
Enter a scaling factor separately for each axis:
Entry value > 1: workpiece will “grow”
Entry value = 1: workpiece will remain the same size
Entry value < 1: workpiece will “shrink”
Input range:
0.100000 to 9.999999
Factory setting: 1.000000
P23 Display of position values for measured
value output 1) 2)
When a measured value is output through pulse, contact or
CTRL B it is first latched (stored in a buffer) and then sent over
the RS-232-C interface. Parameter P23 selects the display
mode for the latching process.
Operating Parameters
