Overview of Alarms
NCK alarms
4260 Machine data %1 illegal
Parameters: %1 = String: MD identifier
Definitions: Selected cam pair not activated by MD $MN_SW_ASSIGN_TAB or several cam pairs selected.
Reaction: Mode group not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Activate the cam pair or select only one cam pair.
Program Switch control OFF - ON.
Continuation:
4270 Machine data %1 assigns not activated NCK input/output byte %2
Parameters: %1 = String: MD identifier
%2 = Index
Definitions: The specified machine data assigns a digital input/output byte or an analog input/output signal the
processing of which has not been activated to an NC function.
Reaction: NC not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Correct machine data. Activate required
inputs/outputs via MDs:
- $MN_FASTIO_DIG_NUM_INPUTS
- $MN_FASTIO_DIG_NUM_OUTPUTS
- $MN_FASTIO_ANA_NUM_INPUTS
- $MN_FASTIO_ANA_NUM_OUTPUTS
Activation of fast inputs/outputs does not require the corresponding hardware configuration to be
available at the control. All functions using fast inputs/outputs can also be made use of by the PLC
specification/modification defined in the VDI interface, if the response time requirements are reduced
accordingly.
Activated inputs/outputs increase the computation time requirement of the interpolation cycle because
the PLC manipulation signals are handled cyclically. Note: Deactivate any inputs/outputs not in use.
Program Switch control OFF - ON.
Continuation:
4275 Machine data %1 and %2 both assign the same NCK output byte no. %3
several times
Parameters: %1 = String: MD identifier
%2 = String: MD identifier
%3 = No. of output
Definitions: The specified machine data assign two NC functions to the same digital/analog output.
Reaction: NC not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Correct machine data.
Program Switch control OFF - ON.
Continuation:
