6.1.21 VarXTouchProbeSynchronisation
Inputs
Global variables (Variable type: VAR_GLOBAL)
Enable print-mark synchronisation.
TRUE
Print-mark synchronisation enabled.
g_bXTpEnable BOOL
FALSE Print-mark synchronisation disabled.
Start ramp generator to correct position deviations.
FALSE => TRUE
The position deviation calculated
(g_dnXDifference_p) is
corrected via the internal ramp
generator.
g_bRfgXTpExecute BOOL
FALSE The ramp generator is not active and the
position deviation calculated
is not corrected. The starting position is
retained.
Selection of correction mode for print-mark synchronisation.
TRUE Correct measured distance via internal
ramp generator.
g_bRfgXTpEnable BOOL
FALSE Correct measured distance via constant
speed value at
g_nXTpMakeUpLeeway_v.
Trigger input for calculating position deviation g_bXTpReceived BOOL
FALSE => TRUE Recalculate position deviation.
g_nXTpMakeUpLeeway_v INT Speed in [incr./ms] for correcting the calculated position deviation.
• Only relevant for correction via constant speed value
(g_bRfgXTpEnable = FALSE). Internal limitation to 0 ...
g_dnVertShaftLengthAct_p
g_dnXTpPos DINT Distance from zero point to touch-probe sensor in [m_unit]
• Internal limitation to 0 ... 2 * g_dnVertShaftLengthAct_p
• The value is entered in fixed point format with 4 decimal positions (1
[unit]/10000). The value is converted into increments internally.
• The variable is a retain variable.
If you use this variable, to avoid inconsistencies, do not write variable
g_dnXTpPos_p!
g_dnXTpPos_p DINT Distance from zero point to TP sensor in [incr.]
If you use this variable, to avoid inconsistencies, do not write variable g_dnXTpPos!
g_dnXTpActLastScan_p DINT Δ incr between touch probe and start of task
Outputs
Global variables (Variable type: VAR_GLOBAL)
Name Data type Value/Meaning
Status of print-mark synchronisation.
TRUE Synchronisation active, correcting X
difference.
g_bXTpSyncBusy BOOL
FALSE No correction of setpoint currently
active.
g_dnXDifference_p DINT Correction value for touch-probe signal
• Only if g_bRfgXTpEnable = TRUE.
g_dnXTpDifference_p DINT Difference between two touch-probe signals
• Only if g_bRfgXTpEnable = TRUE.
