Correct NC part program. Create the zero mark synchronization by positioning, by rota-
tion (at least 1 revolution) in speed control mode or G74 before switching the alarm gener-
ating function on.
Clear alarm with the Delete key or NC START.
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 func-
tion. 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).
- Alarm display.
- NC Stop on alarm.
- Interface signals are set.
• 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.
Channel %1 block %3 spindle %2 no transition from speed control mode to position
control mode
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
• An oriented spindle stop (SPOS/SPOSA) has been programmed or the position control
of the spindle was switched on with SPCON but no spindle encoder has been defined.
• When switching on the position control, the spindle speed is greater than the limiting
speed of the measuring system.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
Spindle without attached encoder: Any NC language elements requiring the encoder sig-
nals must not be used.
Spindle with attached encoder: Enter the number of spindle encoders used in the MD
NUM_ENCS.
Clear alarm with the RESET key. Restart part program
