Channel %1 block %2 following spindle %3 'Synchronism follow-up' diagnostics
%4.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
%4 = Diagnostics
Definitions: The following situation has occurred during 'Correct synchronims':
- Diagnosis 1: An existing override motion is terminated on key reset.
- Diagnosis 2: An existing override motion was cleared (e.g. key reset)
- Diagnosis 3: Write override value impermissible. Override motion is stopped.
- Diagnosis 4: Override motion is stopped intermittently (e.g. G74 reference point
approach)
- Diagnosis 5: Currently no dynamic response available for an override motion.
- Diagnosis 6: Currently no speed available for an override motion.
Machine data 11411 ENABLE_ALARM_MASK Bit9 = 1 activates this alarm.
Reactions: - Alarm display.
Remedy: Deactivation of the alarm with machine data 11411 ENABLE_ALARM_MASK Bit9 = 0.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22034
Channel %1 block %2 following spindle %3 PLC signal 'Enable override' has been
set.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
Definitions: PLC signals DB31..,DBX31.6 'Correct synchronism' and DB31.., DBX26.4 'Override
enable' must not be set at the same time. If an override motion exists for the following
spindle, override value $AA_COUP_CORR[Sn] cannot be calculated properly.
Reactions: - Alarm display.
Remedy: Set PLC signal DB31.., DBX26.4 'Override enable' to 0.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22035
Channel %1 block %2 following spindle %3 unable to determine the offset value
(cause %4).
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
%4 = Reason
Definitions: Determination of override value ($AA_COUP_CORR[Sn]) intended by VDI signal
DB31..,DBX31.6 'Correct synchronism' cannot be executed. The reasons may be:
• Reason 1: An additional following spindle motion exists. The override value can there-
fore not be calculated properly.
• Reason 2: No following spindle synchronism exists on setpoint side. The override value
can therefore not be calculated properly.
• Reason 3: The override value has already been set or determined.
Reactions: - Alarm display.
Remedy: The following remedies are available for the indicated reasons:
• Reason 1: Wait for termination of the override motion before you set PLC signals
DB31..,DBX31.6 'Correct synchronism'.
