SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_EXT_STOP_INPUT[0...3]
Input assignment, external brake request
Min. input limit: 0
Protection level: 7/2
This data defines the NCK inputs to select/deselect the external brake requests.
Structure: Coding of the input assignment, see Page 8-412
n = 0, 1, 2, 3 stands for various braking types
n = 0: Assignment for "deselect external STOP A" (SH, pulse cancellation)
n = 1: Assignment for "deselect external STOP C" (braking at the current limit/OFF3 ramp)
n = 2: Assignment for "deselect external STOP D" (braking along a path)
n = 3: Assignment for "deselect external STOP E" (ESR, braking along a path)
The signal "deselect external STOP A" can not be parameterized inverted. In the case of an
error, a parameterizing error is signaled
$MA_SAFE_OVR_INPUT[0...3]
Input assignment, SG override
Min. input limit: 0
Protection level: 7/2
Assigns the NCK inputs for the correction of the limit value of the safely reduced speeds 2
and 4.
Structure: Coding of the input assignment, see Page 8-412
n = 3, 2, 1, 0 stand for correction selection bits 3, 2, 1, 0
Assigns the input bits to the SG correction values:
Bit 3 Bit 2 Bit 1
0 0 0
0 0 0
Up to
1 1 1
The correction factor itself (percentage) is defined using the following machine data:
MD36932 $MA_SAFE_VELO_OVR_FACTOR[n]
Note:
- - The function "correction, safely reduced speed" is enabled using MD36901
$MA_SAFE_FUNCTION_ENABLE bit 5.
MD36932 $MA_SAFE_VELO_OVR_FACTOR[n]
See Chapter 6.5.4: "Override for safely reduced speed"
Max. input limit: 84020620
Max. input limit: 84020620
Bit 0
0 correction 0 is selected
1 correction 1 is selected
1 correction 15 is selected
