Channel %1 axis %2 measuring system error

Parameters:

%1 = Channel number

Definitions:

%2 = Axis name, spindle number

In a measuring system with distance-coded reference marks, the distance between two adjacent markers has been found to be more than twice the distance entered in the machine data 34300 ENC_REFP_MARKER_DIST.

Reactions:

The control issues the alarm after having made a second attempt in reverse direction with half the traversing velocity and detecting that the distance is too large again.

- NC Start disable in this channel.

Remedy:

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Determine the distance between 2 odd reference point markers (reference point marker interval). This value (which is 20.00 mm on Heidenhain scales) must be entered in the machine data 34300 ENC_REFP_MARKER_DIST.

Program Continuation:

Check the reference point track of the scale including the electronics for the evaluation. Clear alarm with the RESET key. Restart part program
