4-230 SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Additional parameterization for local inputs on the NCU (from SW 6.3.21):
s = 0 Local inputs on the NCU
s = 1 I/Os on the 611 digital bus
s = 4 System variable assignment, internal image in the
system memory
• Parameterization for s = 0 for axial SGEs:
mm =00H fixed
xx =00H fixed
nn =01H – 04H Bit number

MD number
$MA_SAFE_SVSS_DISABLE_INPUT
Input assignment, SBH/SG de-selection
840D
Default: 0 Min. input value: 0 Max. input value: -
Change becomes effective after POWER ON: Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 3.4
Meaning
Design:
This data defines the NCK input for selection/de-selection of the SBH and SG functions.
Signal means
= 0 SG or SBH is selected
= 1 SG and SBH are de-selected
Special cases, errors
• 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)

$MA_SAFE_SS_DISABLE_INPUT
Input assignment, SBH de-selection
840D
Default: 0 Min. input value: 0 Max. input value: -
Change becomes effective after POWER ON: Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 3.4
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 means
= 0 Safe operating stop is selected
= 1 Safely-reduced speed is selected
(only if STOP C, D or E has not been activated by other functions)
Special cases, errors
• 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).
