Overview of Alarms
• Reason 2: Wait until synchronism is achieved on setpoint side before you set PLC sig-
nal DB31..,DBX31.6 'Correct synchronism'.
• Reason 3: Set override value $AA_COUP_CORR[Sn] to 0 prior to setting PLC signal
DB31..,DBX31.6 'Correct synchronism'.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22036
Channel %1 block %2 following spindle %3 synchronism offset not possible.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
Definitions: Synchronism override intended by setting VDI signal DB31..,DBX31.6 'Correct synchro-
nism' or writing variable $AA_COUP_CORR[Sn] can currently not be considered.
The reasons may be:
• Reference point approach or zero mark synchronization is active
• NC reset is running
Reactions: - Alarm display.
Remedy: Wait until the conditions for override value processing are available again prior to setting
PLC signal DB31..,DBX31.6 'Correct synchronism' or writing variable
$AA_COUP_CORR[Sn].
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22040
Channel %1 block %3 spindle %2 is not referenced with zero marker
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The current position is not referenced with the MS position although reference is made to
it.
Reactions: - Alarm display.
Remedy: 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.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22045
Block %2 spindle/axis %3 not available in channel %1 because active in channel
%4
Parameters: %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.
Definitions: 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 spin-
dle/axis is not contained in the channel programmed for the coupling at the time the cou-
pling 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).
