Sinumerik Alarm 20160 Channel %1 tool management: PLC can terminate only incorrectly aborted commands
%1 = Channel number
Indication that the PLC wanted to interrupt an active command from the tool management (tool change); or that there is no command active for abort. NCK refuses because the channel status is either ‘active’ (abort is then not allowed), or ‘reset’ (then there is nothing to abort).
– Alarm display.
– Interface signals are set.
For information only.
Clear alarm with the Delete key or NC START.
