Definitions: The axis is active in a coupling as a following axis. The master axes
have different states regarding axis/spindle disable.
The alarm can be suppressed with machine data 11415 SUPPRESS_ALARM_MASK_2 Bit0 =1.
Reaction: Alarm display.
Remedy: Set the same axis/spindle disable for all master axes.
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
16774 Channel %1 Synchronization aborted for slave axis/spindle %2
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: For the indicated axis, the synchronization procedure (EGONSYN or EGONSYNE) was aborted.
There are several reasons for aborting the synchronization process:
- RESET
- End of program
- Axis goes to follow-up mode
- Rapid stop caused by an alarm
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: If the abort of the synchronization procedure can be tolerated or is intended, the alarm can be sup-
pressed with machine data 11410 SUPPRESS_ALARM_MASK Bit31 = 1.
Only applicable for electronic gear (EG):
If it is not possible to abort the synchronization procedure, you can achieve it by specifying the block
change criterion FINE in EGONSYN or EGONSYNE.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16777 Channel %1 block %2 coupling: following axis %3 for lead axis %4 not
available
Parameters: %1 = channel number
%2 = block number, label
%3 = axis name, spindle number
%4 = axis name, spindle number
Definitions: A coupling has been switched on in which the slave spindle/axis is currently not available. One pos-
sible cause:
The spindle/axis has been under the control of the PLC and has not yet been released.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Put the master spindle/axis with spin-
dle/axis exchange into the necessary channel or release from the PLC.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16778 Channel %1 block %2 coupling: Ring coupling at following axis %3 and
leading axis %4 impermissible
Parameters: %1 = channel number
%2 = block number, label
%3 = axis name, spindle number
%4 = axis name, spindle number
Definitions: A coupling has been switched on which will create a ring coupling when other couplings are taken into
account. This ring coupling cannot be uniquely computed.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
