20210 Channel %1 block %3 spindle %2 wrong values for centerless grinding
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Block number, label
Definitions: It was not possible to calculate a tool diameter (no speed specified for the spindle) for centerless
grinding because it was not allowed by the input positions. The old S value still applies.
Reaction: Alarm display.
Remedy: - Modify program
- Select new traversing positions for centerless axes
- or suppress computation by G00.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20211 Channel %1 block %3 spindle %2 support point beyond range limits
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Block number, label
Definitions: The support point calculated for centerless grinding is beyond the range limits.
Machine data:
Modify MD 21518: TRACLG_CONTACT_UPPER_LIMIT
Modify MD 21520: TRACLG_CONTACT_LOWER_LIMIT
Reaction: Alarm display.
Remedy: - Check centerless axis positions and machine data.
- Modify program.
- Select new traversing positions for centerless axes
- or suppress computation by G00.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20300 Channel %1 axis %2 orientation not possible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: On traversing the displayed (virtual) orientation axis, a tool orientation is to be set
for which the kinematics of this machine are not possible.
Reaction: Alarm display.
Remedy: Abort the JOG movement and specify another (possible)
change of orientation.
Program Clear alarm with the Delete key or NC START.
