Channel %1 block %3 spindle %2 actual gear stage differs from requested gear
stage
%1 = Channel number
%2 = Spindle number
%3 = Block number, label
The requested gear stage change has been concluded. The actual gear stage reported by
the PLC as being engaged is not the same as the required gear stage called for by the
NC. Note: Wherever possible, the requested gear stage should always be engaged.
- Alarm display.
Please inform the authorized personnel/service department. Correct the PLC program.
Clear alarm with the Delete key or NC START.
Channel %1 block %3 spindle %2 change to programmed gear stage not
possible
%1 = Channel number
%2 = Spindle number
%3 = Block number, label
With the 'DryRun', 'ProgramTest' and 'SearchRunByProgTest' functions deselected, it is
not possible in the Repos module to carry out a gear stage change to a previously pro-
grammed gear stage. This is the case, if the spindle is in the deselection block not active
in speed control mode, as a slave axis or in a transformation. Execution of a gear stage
change is avoided if the above mentioned functions are deselected by resetting bit 2 of
machine data 35035 SPIND_FUNCTION_MASK.
- Alarm display.
Change deselection block or block search target block to speed control mode (M3, M4,
M5, SBCOF). Set bit 2 of machine data 35035 SPIND_FUNCTION_MASK to 0.
Clear alarm with the Delete key or NC START.
Channel %1 block %2 leading spindle %3 is in simulation.
%1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
When coupling, no synchronism can be achieved if the lead spindle/axis is in simulation
mode and the following spindle/axis is not.
- Alarm display.
Set the following spindle/axis to simulation mode, or do not simulate the lead spindle/axis
($MA_CTRLOUT_TYPE). If the differing settings have been selected on purpose, the
alarm can be suppressed with the machine data 11410 SUPPRESS_ALARM_MASK
Bit21 = 1.
Clear alarm with the Delete key or NC START.
Channel %1 block %2 dependent spindle %3 is in simulation.
%1 = Channel number
%2 = Block number, label
%3 = Following spindle number
When coupling, no synchronism can be achieved if the following spindle/axis is in simula-
tion mode and the lead spindle/axis is not.
- Alarm display.
