Setting the parameters for the shut-down behavior
If D-Slaves respond to a shutdown in the PROFIBUS communication, e.g. NC reset during
operation, with fault conditions, you can assign parameters for a successive shutdown of the
PROFIBUS communication using the following machine data:
●
MD11250 $MN_PROFIBUS_SHUTDOWN_TYPE (PROFIBUS shutdown handling)
Note
The following drives can be operated in mode 0 (immediate shutdown).
•
SINAMICS S120
•
SIMODRIVE 611U/UE, POSMO SI/CD/CA

PROFIBUS shutdown handling
Default setting: 0
Min. input limit: 0
Max. input limit: 2
Changes effective after RESET
Protection level: 2/7
unit: -
Data type: UINT8
Valid as of software version: 2.2
Meaning:
Shut-down modes of PROFIBUS DP communication:
0 = The PROFIBUS DP communication is shut down at the DP master end without any
warning.
1 = The PROFIBUS DP is moved to the CLEAR state for at least 20 cycles. The PROFIBUS
DP communication is finally shut down. If the PROFIBUS DP cannot be switched to the
CLEAR state, please proceed as described in 2.
The following is to be used with: SINUMERIK 840D with DP-Link module.
2 = Zero values are transmitted for at least 20 clock cycles for all DP slave drives connected
to PROFIBUS DP for the following frame data:
•
Control word 1
•
Control word 2
The PROFIBUS DP communication is finally shut down.
To be used with: SINUMERIK 840Di sl in conjunction with external drives.
