Detailed Description
2.1 General functionality
SERUPRO
Block search with calculation, multichannel
The block search in program test mode is designated SERUPRO and is derived from the
"Search-Run by Program test." This search mode allows the user a multichannel block
search with calculation of all required status data from the previous history.
The PLC interface is updated in this block search and matching processes, which cover the
interaction of several channels executed within the framework of this block search correctly.
Search process with FXS and FOC
The user selects FXS or FOC in a program area of the searched target block in order to
acquire all states and functions of this machining last valid. The NC will start the selected
program in Program test mode automatically. After the target block has been found, the NC
stops at the beginning of the target block, deselects Program test internally again and
displays the Stop condition "Search target found" in its block display.
If FXS "travel to fixed stop" is located between the beginning of the program and the search
target, the instruction is not really executed by the NC. The motion is only simulated up to
the programmed end point.
Caution
SERUPRO approach does not really take the statementFXS into account. The approach to
the programmed end position of the FXS block is only simulated without torque limitation.
The user can log the turning on and turning off of FXS in the parts program. If necessary, the
user can start an ASUB in order to activate or deactivate FXS in this SERUPRO-ASUP.
