NCK alarms
26286 [Channel %1: ] Axis %2 risk of collision preactivated protection zones
interface signal(s) %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Interface signal(s)
Definitions: A collision was detected involving at least one preactivated protection zone.
Such a collision can occur if the interface signal assigned to a preactivated protection zone has been
activated. That is if a preactivated protection zone has become an active protection zone.
Either a preactivated and a (static) active protection zone can be involved in the collision, or two pre-
activated protection zones can be involved. The number(s) of the interface signals assigned to the
preactivated protection zones involved are output in the alarm text.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Alarm reaction in Automatic mode.
NC Stop on alarm.
Remedy: Reset activating interface signals.
Redefine protection zones.
Retract
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26290 [Channel %1: ] Block %2: Maximum number of %4 protection zone facets
exceeded in CAD file %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = File name
%4 = Maximum number of protection zone facets
Definitions: The maximum permissible number of protection zone facets has been exceeded.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Increase the number of allowed Protection Area Facet elements (MD18895
$MN_MM_MAXNUM_3D_FACETS) or reduce the number of defined facets in the CAD file.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:

Definitions: The maximum permissible number of input points has been exceeded.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Increase the number of allowed Protection Area Facet elements (MD18895
$MN_MM_MAXNUM_3D_FACETS) or reduce the number of defined facets in the CAD file.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26294 [Channel %1: ] Block %2: CAD file %3 is not a valid VRML file
Parameters: %1 = Channel number
%2 = Block number, label
