SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MA_SAFE_SVSS_DISABLE_INPUT
Input assignment, SBH/SG de-selection
Min. input limit: –
Protection level: 7/2
This machine data defines the NCK input to select/de-select the SBH and SG functions
Signal Means
= 0 SG or SBH is selected
= 1 SG and SBH are de-selected
Structure: Refer to the coding of the input assignment
S
Input value of 0 means: There is no assignment, the input remains fixed at 0, SG and
SBH cannot be de-selected
S
Input value of 80 00 00 00 means: There is no assignment, the input remains fixed at 1
S
If MD bit 31 is set, then the signal is processed inverted (i = 8).
$MA_SAFE_SS_DISABLE_INPUT
Input assignment, SBH de-selection
Min. input limit: –
Protection level: 7/2
Assignment of the NCK input to de-select the safe operating stop function.
Structure: Refer to the coding of the input assignment
Assignment of the 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 Safe operating stop is de-selected (only if STOP C, D or E has not been
activated by other functions)
S
If MD bit 31 is set, then the signal is processed inverted (i = 8).
S
This input is of no significance if SG and SBH have been de-selected (refer to
$MA_SAFE_SVSS_DISABLE_INPUT).
