36972 $MA_SAFE_VELO_SELECT_INPUT[n]
MD number Input assignment, SG selection
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data defines the two inputs for selecting SG1, SG2, SG3 or SG4.
Structure: Refer to coding of input assignment
n = 1, 0 stands for bits 1, 0 for selecting SG1 to SG4
Assignment of input bits to safely-reduced speeds:
Bit 1
0
0
1
1
Special cases, errors If the MD bits 31 are set, then the signal is processed inverted (ss = 81).

36973 $MA_SAFE_POS_SELECT_INPUT
MD number Input assignment, SE selection
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data defines the input for selecting safe limit position 1 or 2.
Structure: Refer to coding of input assignment
Signal
= 0
= 1
Special cases, errors If MD bit 31 is set, then the signal is processed inverted (ss = 81)

36974 $MA_SAFE_GEAR_SELECT_INPUT[n]
MD number Input assignment, gear ratio selection
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning Assignment of the input terminals for selecting the gear ratio (gear stage).
Structure: Refer to coding of input assignment
n = 2, 1, 0 stands for bits 2, 1, 0 for selecting gear stages 1 to 8

MD number Input assignment, "test stop selection"
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data defines the input for selecting the test stop.
Structure: Refer to coding of input assignment
Signal
= 0
= 1
Special cases, errors If MD bit 31 is set, then the signal is processed inverted (ss = 81)
