Detailed Description
2.4 Program test
Mode Group, Channel, Program Operation, Reset Response (K1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-19
Selection
This function is selected via the operator interface in the "Program control" menu.
This selection sets interface signal:
DB21, ...DBX25.7 (program test selected).
This does not activate the function.
Activation
The function is activated via interface signal:
DB21, ... DBX1.7 (activate program test)
Display
As feedback that the program test is active, the appropriate field on the operator interface is
reversed and interface signal:
DB21, ... DBX33.7 (program test active)
is set.
Caution
The signals for exact stop:
DB31, ... DBX60.6/60.7 (exact stop coarse/fine)
mirror the actual status on the machine.
They are only canceled during program testing if the axis is pushed out of its set position (the
set position remains constant during program testing).
With signal:
DB21, ... DBX33.7 (program test active)
both the PLC program and the part program can use variable
$P_ISTEST
to decide how to react or branch in response to these signals during testing.
Program execution without axis motion can also be activated with the function dry run
feedrate. With this function, part program sections with a small programmed feedrate can be
processed in a shorter time.
Tool management
Because of the axis disable, the assignment of a tool magazine is not changed during
program testing. A PLC application must be used to ensure that the integrity of the data in
the tool management system and the magazine is not corrupted. The toolbox diskettes
contain an example of the basic PLC program.
