4.1 Machine data
Additional parameterization for local inputs on the NCU (from SW 6.3.21):
s = 0
s = 1
s = 4
•
36970 $MA_SAFE_SVSS_DISABLE_INPUT
MD number Input assignment, SBH/SG de-selection
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data defines the NCK input for selection/de-selection of the SBH and SG functions.

36971 $MA_SAFE_SS_DISABLE_INPUT
MD number Input assignment, SBH de-selection
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning Assignment of the NCK input for de-selecting the safe operating stop function.
Design: See coding of input assignment
Assignment of terminal signal level to the safe functions if safely-reduced speed or safe
operating stop has been activated.
Signal
= 0
= 1
(only if STOP C, D or E has not been activated by other functions)

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Local inputs on the NCU
I/Os on the 611 digital bus
System variable assignment, internal image in the
system memory
Parameterization for s = 0 for axial SGEs:
mm =00H
xx =00H
nn =01H – 04H
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 3.4
means
SG or SBH is selected
SG and SBH are de-selected
Input value "0" means:
There is no assignment, the input remains at 0, SG and SBH cannot be de-selected.
Input value "80 00 00 00" means:
There is no assignment, the input remains at 1
If MD bit 31 is set, then the signal is processed inverted (ss = 81)
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 3.4
means
Safe operating stop is selected
Safely-reduced speed is selected
If MD bit 31 is set, then the signal is processed inverted (ss = 81)
This input is of no significance if SG and SBH have been de-selected (see
$MA_SAFE_SVSS_DISABLE_INPUT).
