4-235
36982
MD number
$MA_SAFE_VELO_STATUS_OUTPUT[n]
Output assignment, SG active
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 4.2
Meaning This data determines the outputs or system variables for the "SG active bit 0" and "SG
active bit 1" signals.
Structure: Refer to coding of output assignment
n = 1, 0 stands for SG active, bits 1, 0
SG active
Bit 1 Bit 0 means
= 0 = 0 SG1 active if SBH/SG is active and SBH is not active
SBH active if SBH/SG and SBH are active
= 1 = 0 SG2 active
= 0 = 1 SG3 active
= 1 = 1 SG4 active
Special cases, errors
• If a single output signal is connected to a terminal, the following applies:
If MD bit 31 is set, then the signal is processed inverted (ss = 81)
• If several output signals are connected to the same terminal, the following applies:
If MD bit 31 is set (ss = 81), the relevant signal is initially inverted.
The (in some cases inverted) output signals are then ANDed and the result output at
the terminal.
36984
MD number
$MA_SAFE_EXT_PULSE_ENAB_OUTPUT
Assignment of output terminal for selection of "external pulse enable"
840D
Default: 0 Min. input value: 0 Max. input value: 0x811E0810
Change becomes effective after RESTART Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 6.3
Meaning This MD must be parameterized as soon as the internal pulse cancellation is used (bit 30
in $MA_SAFE_PULSE_ENABLE_OUTPUT=1)
Structure: Refer to coding of input assignment
With each machine data of this kind, a single I/O bit is connected to a terminal or a system
variable. Otherwise, the structure of the machine data is as for 36970 and onwards.

MD number
$MA_SAFE_VELO_X_STATUS_OUTPUT
Output assignment for n < n
x
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 4.2
Meaning This data determines the output or system variable for the "n < n
x
" signal.
Structure: Refer to coding of output assignment
Signal means
= 0 Actual speed is higher than the limit speed in $MA_SAFE_VELO_X
= 1 Actual speed is lower or equal to the limit speed
Corresponds with … $MA_SAFE_VELO_X
Special cases, errors
• If a single output signal is connected to a terminal, the following applies:
If MD bit 31 is set, then the signal is processed inverted (ss = 81)
•
If several output signals are connected to the same terminal, the following applies:
If MD bit 31 is set (ss = 81), the relevant signal is initially inverted.
The (in some cases inverted) output signals are then ANDed and the result output at
the terminal.
