Overview of Alarms
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21616
Channel %1 block %2 overlaid motion active at transformation switchover
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The overlaid motion in the BCS changes its significance because of the transformation
change and can therefore lead to undesired axis movements.
Reactions: - Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Take out the overlaid movement.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
21617
Channel %1 block %2 transformation does not allow to traverse the pole
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The preset curve passes through the pole or a forbidden area of the transformation.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Modify part program (if alarm has occurred in AUTO mode).
To escape from the alarm position, transformation must be deselected (it is not enough to
try a RESET if the transformer remains active when RESET is applied).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21618
Channel %1 as from block %2 transformation active: overlaid motion too great
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The share of overlaid motion on the transformation-related axes is so high that the path
movement planned by the preparation no longer sufficiently corresponds to the actual
ratio for the interpolation. Strategy of singularities, monitoring of working range limitation
and dynamic Look Ahead are possibly no longer correct.
Reactions: - Alarm display.
Remedy: With overlaid motion it is necessary to keep a sufficiently large path safety distance with
regard to poles and working range limitations.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
21619
Channel %1 block %2 transformation active: motion not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The machine kinematics does not allow the specified motion. Transformation-dependent
error causes can be in:
TRANSMIT: A (circular) area exists around the pole, where positioning is not possible.
The area is caused by the fact that the tool reference point cannot be traversed as far as
into the pole. The area is defined by:
