Definitions: The indicated axis was stopped due to the risk of collision.
Reaction: Alarm display.
Remedy: In JOG mode: Retract axis from danger zone.
In automatic mode: Determine reason for the risk of collision and eliminate. Possible reasons: wrong
NC program, too large handwheel overrides, axis couplings and vice-versa impairing of two channels.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
26281 [Channel %1: ] Axis %2 risk of collision %3 %4
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = 1st protection zone
%4 = 2nd protection zone
Definitions: The stated axis was stopped due to the risk of collision. The programmed path may have been left
because it was not possible to stop in time on the path (exceptional situation).
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: In JOG mode: Retract axis from danger zone.
In automatic mode: Determine reason for the risk of collision and eliminate. Possible reasons: wrong
NC program, too large handwheel overrides, axis couplings and vice-versa impairing of two channels.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation: The stated axis was stopped due to the risk of collision. The programmed path may have been left
because it was not possible to stop in time on the path (exceptional situation).
26282 [Channel %1: ] Block %2: Invalid definition of the protection zones or the
kinematic chains.
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: There are no valid definitions of the protection zones and / or the kinematic chains.
This alarm only occurs if an error occurred the last time the procedure PROTA was called, and its
cause has not been eliminated.
Reaction: Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy: Protection zones and kinematic chains must be defined without errors.
This is achieved by calling the procedure PROTA and closing it without errors.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26284 [Channel %1: ] Block %2: The call of the function / procedure %3 is only
permissible if the function 'Collision monitoring' is present.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Funktionsname
Definitions: The function or procedure stated in the alarm text (e.g. PROTA or PROTD) can only be called if the
function "Collision avoidance" is present.
Reaction: Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy: The function "Collision avoidance" must be activated. For this, the MD18890
$MN_MM_MAXNUM_3D_PROT_AREAS must contain a value greater than zero.
Program Con- Clear alarm with NC START or RESET key and continue the program.
