%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.
Reactions: - Alarm display.
Remedy: Abort the JOG movement and specify another (possible)
change of orientation.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
21550
Channel %1 axis %2 Travel from hardware limit switch not possible. Reason: %3
Parameters: %1 = Channel number
%2 = Axis name
%3 = Cause
Definitions: It has been tried to retract a following axis of an axis coupling or an output axis of a trans-
formation through the master axis or input axis of a transformation. This is not permitted in
the current situation.
Possible reasons:
1 No permissible direction of retraction
2 Coupling not synchronous
3 Retraction not permitted for the active coupling
4 Reserved
5 Retraction not permitted for the active transformation
Reactions: - NC Start disable in this channel.
- Alarm display.
Remedy: Remedy for error cause:
1 Define another travel direction
2 Deactivate the coupling and travel the axis/axes separately
3 Deactivate the coupling and travel the axis/axes separately
4 Reserved
5 Deactivate the transformation and travel the axis/axes separately
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21600
Monitoring for ESR active
Definitions: -
Reactions: - NC not ready.
- Alarm display.
- All alarm reactions are delayed by one IPO cycle with this alarm.
Remedy: The display can be suppressed with the machine data MD 11410:
SUPPRESS_ALARM_MASK Bit 16 = 1
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
21610
Channel %1 axis %2 encoder %3 frequency limit exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = String (encoder number)
Definitions: The maximum permissible frequency of the currently active encoder (axis-specific inter-
face signal DB 31 - 48, DBX 1.5 and DBX 1.6) in the axis-specific machine data 36 300
ENC_FREQ_LIMIT [n] (n ... encoder number, 1 or 2) has been exceeded. The reference
of the actual value to the mechanical carriage position may be lost.
