Description of the parameterization of the SGA machine data MD36980 to MD36990 and MD37901 to
37909
This machine data involves eight-digit hexadecimal numbers, where each digit has a different
significance, which is now explained:
Coding of the output assignment is mm xx nn
i
s
mm
xx
nn
● Input value of 0 means: there is no assignment, the output remains unaffected.
● Input value of 80 00 00 00 means: There is no assignment, the output remains fixed at 1

$MA_SAFE_OVR_INPUT[n]: 0 ... 3
Assigns the NCK inputs for the correction of the limit value of the safely reduced speeds 2
and 4.
Structure: Refer to the coding of the input assignment
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 = 0, bit 2 = 0, bit 1 = 0, bit 0 = 0: correction 0 is selected
Bit 3 = 0, bit 2 = 0, bit 1 = 0, bit 0 = 1: correction 1 is selected
to
Bit 3 = 1, bit 2 = 1, bit 1 = 1, bit 0 = 1: correction 15 is selected
The correction factor itself (percentage) is defined using the following machine data:
MD36932 $MA_SAFE_VELO_OVR_FACTOR[n]
● The function "correction, safely reduced speed" is enabled using MD36901
$MA_SAFE_FUNCTION_ENABLE bit 5.
MD36932 $MA_SAFE_VELO_OVR_FACTOR[n]
