Correspondence between marker of channel %1 and channel %2 is invalid.
%1 = Channel ID
%2 = Channel ID
This channel defines a WAIT marker with other channels, which on their part have no cor-
respondence with this wait marker.
This channel's WAIT marker has no explicit counterpart in the other channel; i.e. the
channels do not mutually wait.
============================================================
Example
Ch 3 Ch 5
WAITM(99,3,5) WAITM(99,3,5)
The wait markers in channels 3 and 5 mutually wait for each other and channel 7 only
waits for channel 5. Therefore, channel 7 may continue when 5 and 7 have reached the
wait marker, but channel 3 is still far in front of the wait marker.
When it continues, channel 7 deletes its wait marker. When wait marker 99 is reached
again, you can no longer determine the behavior precisely.
============================================================
- Alarm display.
In each wait marker, list all channels with which you want to synchronize, or suppress the
alarm with $MN_SUPPRESS_ALARM_MASK, bit 23.
============================================================
Sample solution A:
Ch 3 Ch 5
WAITM(99,3,5,7) WAITM(99,3,5,7)
============================================================
Sample solution B:
Ch 3 Ch 5
WAITM(99,3,5) WAITM(99,3,5)
WAITM(88.50.7)
============================================================
Sample solution C:
Ch 3 Ch 5
WAITM(88.50.7)
WAITM(99,3,5) WAITM(99,3,5)
Clear alarm with the Delete key or NC START.
Channel %1 search run with hold block
%1 = Channel ID
Informational alarm.
The search run was not performed on the interruption block,
instead, it touches down shortly before that. This so-called "hold block"
is generated by the part program command IPTRLOCK, or implicitly defined by
$MC_AUTO_IPTR_LOCK. This is to prevent
you from performing a search run in critical program areas
(e.g. gear hobbing).
The alarm also displays that, instead of searching for the
block that actually was interrupted before, another block is being searched for.
This behavior is desired and the alarm serves only informational purposes.
