$MA_SAFE_VELO_SELECT_INPUT[n]: 0 ... 1
Input assignment, SG selection
Min. input limit: –
Protection level: 7/2
This machine data defines the two inputs to select SG1, SG2, SG3 or SG4.
Configuration: Refer to the coding of the input assignment
n = 1, 0 stand for bit 1, 0 to select from SG1 to SG4
Assignment of the input bits to the safely reduced speeds:
Bit 1
Bit 0

If the MD bits 31 are set, then the signal is processed inverted (i = 8).
MD 36970: $MA_SAFE_SVSS_DISABLE_INPUT
$MA_SAFE_POS_SELECT_INPUT
Input assignment, SE selection
Min. input limit: –
Protection level: 7/2
This machine data defines the input to select the safe limit position 1 or 2.
Configuration: Refer to the coding of the input assignment
Signal means
= 0, SE1 is active
= 1, SE2 is active
If MD bit 31 is set, then the signal is processed inverted (i = 8).
