If a MANUALplus 620 with functional safety (FS) is used, there are further
constraints:
Defining an NC operating mode for functional safety in NCK-based controls
The PLC program must select an NC operating mode for systems without
operating-mode group (PNC 610). After booting the system, you must set
parameter 1 to 2 in mode 10 to initiate the homing and testing of the axes.
Then you must use the PLC to switch to one of the two NC operating modes
(e.g. operation through machine operating panel). The system with
Functional Safety is not ready for operation until both of the two
above-mentioned actions have taken place.
Testing the axis positions for functional safety in NCK-based controls
In systems without operating-mode group (PNC 610), the PLC program
must request that the axis positions be tested so that functional safety can
be realized. The user must confirm the test with the permissive button.
Call:
PS B/W/D/K <>Mode>
0: Start self test immediately
1: Prompt the user to start the self-test
10: Define the operating mode for functional safety
11: Request for testing the axis position
PS B/W/D/K <>Parameter1>
0: No evaluation, but must be programmed
1: No evaluation, but must be programmed
PS B/W/D/K <>Parameter2>
Mode 0:
No evaluation, but must be programmed
Mode 1:
No evaluation, but must be programmed
Modus 10:
0: Operation through machine operating panel
1: Operation via electr. handwheel
2: Homing and testing of axes
Mode 11:
0: No evaluation, but must be programmed
1: No evaluation, but must be programmed
10: No evaluation, but must be programmed
11: No evaluation, but must be programmed
