(tolerance for safe operating stop exceeded, STOP a/B) and the drive is
switched into the safe standstill condition.

$MD_SAFE_VELO_LIMIT[n]
611 digital
Limit values for safely-reduced speed
Relevant for:
FD/MSD
Unit: mm/min or
rev/min
Default:
2 000
Minimum value
0
Maximum value:
1 000 000
Data type:
float
Becomes
effective:
POWER ON
Limit values for the safely reduced speed monitoring.
n = 0, 1, 2, 3, stands for limit value of SG1, 2, 3, 4
If the actual speed is greater than this limit value, then the drive initiates a stop
response (this can be parameterized in MD 1361:
$MD_SAFE_VELO_STOP_MODE) and switches into the safe operating stop.
With active SBH/SG and a 1-encoder system, the speed is monitored on the
basis of an encoder limit frequency of 200kHz (300 kHz, 840D from SW 3.6).
The parameterized stop response is output when the limit is exceeded.
1332
$MD_SAFE_VELO_OVR_FACTOR[n]
611digital
Correction factor for SG
Relevant for:
FD/MSD
Valid from:
SW version 4.2
Unit:
%
Default:
100
Minimum value:
1
Maximum value:
100
Data type:
short integer
Becomes
effective:
POWER ON
It is possible to select overrides via SGEs for safely-reduced speeds 2 and 4
and to set the associated override value (percentage) in this machine data.
n = 0, 1, ... , 15 stand for overrides 0, 1, ... 15
The "override for safely-reduced speed" function is enabled via MD 36901
(MD 1301): $MA($MD)_SAFE_FUNCTION_ENABLE (refer to Chapter 3.4.5
"Override for safely-reduced speed").
1334
$MD_SAFE_POS_LIMIT_PLUS[n]
611 digital
Upper limit value for safe end position
Relevant for:
FD/MSD
Unit:
µ
m or
mdegrees
Default:
100 000 000
Minimum value:
-2 147 000 000
Maximum value:
2 147 000 000
Data type:
long integer
Becomes
effective:
POWER ON
Upper (positive) limit value for safe monitoring of a limit position
n = 0, 1 stands for safe limit position SE1, SE2
When passing the active, upper limit value, the drive initiates an alarm (this can
be parameterized using MD 1362: $MD_SAFE_POS_STOP_MODE) and
switches into the safe operating stop.
1335
$MD_SAFE_POS_LIMIT_MINUS[n]
611digital
Lower limit value for safe end position
Relevant for:
FD/MSD
Unit:
µ
m or
mdegrees
Default:
-100 000 000
Minimum value:
-2 147 000 000
Maximum value:
2 147 000 000
Data type:
long integer
Becomes
effective:
POWER ON
Lower (negative) limit value for SE.
n = 0, 1 stands for safe end position SE1, SE2
