Scale Zero Point/Base Point Distance Out of Range

What does DS1448 mean?

This alarm is issued if the distance from the scale zero point (for a linear scale with absolute address reference marks) or the base point (for a linear scale with an absolute address zero point) to the machine's reference position, as configured by parameters 1883 and 1884, exceeds the allowable range of -999,999,999,999 to +999,999,999,999. This indicates an invalid parameter setting for the reference position.

• Scale zero point distance exceeds maximum allowable value.
• Base point distance measurement is out of specification.
• Calibration error detected in the scale measurement system.
• Physical limit for scale zero point exceeded.

Click steps to track your progress.

1. 1

   Check parameters 1883 and 1884 — verify the set machine coordinate value, converted to detection units (machine coordinate × CMR), is within the range of -999,999,999,999 to +999,999,999,999.

2. 2

   Ensure that the physical scale area on the linear scale does not extend across the scale zero point or base point, as this can cause calculation errors.

3. 3

   Re-establish the reference position by following the procedure in the manual (steps <1> through <4> for parameters 1883 and 1884), paying close attention to the machine coordinate measurement.
