Increase MD 34 060 REFP_MAX_MARKER_DIST, but the value may not
be higher than the distance between 2 zero marks. This would possibly switch
off the monitoring!
Press the RESET key to clear the alarm. Restart part program.
Channel %1 axis %2 reference mark missing
%1 = Channel number
%2 = Axis name, spindle number
The required 2 reference marks of the distance-coded length measuring sys-
tem have not been found within the defined search path (axis-specific
MD 34 060 REFP_MAX_MARKER_ DIST).
Distance-coded scales do not need reducing cams. (But if any, it will be evalu-
ated.) The conventional direction key defines the search direction.
The search path REFP_MAX_MARKER_ DIST expected within the 2 refer-
ence marks counts from the start point.
NC Stop at alarm.
NC Start inhibited.
Alarm display.
Interface signals are set.
Determine the distance between 2 odd reference marks (reference-point inter-
val). Then enter this value (in the case of Heidenhain scales, 20.00 mm) in MD
34 060 REFP_MAX_MARKER_DIST.
Check the reference track of the scale incl. evaluation electronics.
Press the RESET key to clear the alarm. Restart part program.
Channel %1 axis %2 reference point approach aborted
%1 = Channel number
%2 = Axis name, spindle number
The channel-specific referencing could not be completed for all axes specified
(e.g. cancellation due to missing servo enable, measuring system change, re-
leasing the direction key, etc.).
NC Stop at alarm.
NC Start inhibited.
Alarm display.
Interface signals are set.
Check cancel facilities:
•
Servo enable missing (V 380x0001.1)
•
Direction keys + or - missing (V 380x0004.6 and .7)
•
Feed override = 0
Which axes are involved in channel-specific referencing is determined by the
axis-specific MD 34 110 REFP_CYCLE_NR.
-1: No channel-specific referencing, NC start without referencing
0: No channel-specific referencing, NC start with referencing.
