RESU Start/Stop/Reset (CC_PREPRE)
Start / stop / reset / of RESU is done with the program instruction:
CC_PREPRE (Prepare Retrace)
Programming
Syntax:
Parameters:
Mode:
CC_PREPRE(...) is a procedure call and must therefore be programmed in a dedicated part
program block.
Functionality
The following modes are available:
Statement
CC_PREPRE(1)
CC_PREPRE(0)
CC_PREPRE(-1)
626
CC_PREPRE(<mode>)
Type:
INTEGER
Range of values: -1, 0, 1
Meaning
Starts logging the traversing blocks.
The information required for reverse travel is logged on a block-specific basis
in a RESU-internal block buffer. The travel information is related to the two
geometry axes of the RESU working plane e.g. the 1st and 2nd geometry axes
of the channel:
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[x]; with x = 0 and 1
Or, if transformation is active:
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB[x]; with x = 0 and 1
Stops logging the traversing blocks.
Thus irrelevant contour areas can be excluded from the log.
These excluded contour areas are bridged by a straight line between the
starting point and end point during reverse travel.
Deactivates logging of the traversing blocks and deletes the function-internal
block buffer. Contour areas located before the instant of deactivation of the
part program are therefore no longer available to RESU.
