Program Continuation:

Block %2 spindle/axis %3 not available in channel %1 because active in channel %4

%1 = Channel number

%2 = Block number, label

%3 = Axis name, spindle number

%4 = Number of the channel in which the spindle/axis is currently active.

The specified spindle/axis is required in channel %1 for the correct execution of a function. The spindle/axis is currently active in the %4 channel. The constellation can only occur with replacement axes.

Problem case: A synchronized spindle coupling was programmed. The master spindle/ axis is not contained in the channel programmed for the coupling at the time the coupling is activated. The master spindle/axis can be moved by FC18 or synchronized actions. When using FC18, please note that the master spindle/axis must be assigned to the channel which activates the coupling. When FC18 terminates, the master spindle/axis must not be assigned to another channel via PLC while the coupling is still active (VDI interface signals).

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Program a GET for the master spindle/axis in the NC program before activating the coupling, or

Assign the master spindle/axis to the channel that activated the coupling via PLC.

Clear alarm with the Delete key or NC START.
