$MA_SAFE_VELO_LIMIT[0...3]
Limit value for safely reduced speed
Min. input limit: 0.0
This MD defines the limit values for safely reduced speeds 1, 2, 3 and 4.
When SG1, SG2, SG3 or SG4 is selected and the actual speed exceeds this limit value, then
the control system initiates Alarm 27011 with the stop response configured in MD36961
$MA_SAFE_VELO_STOP_MODE or MD36963 $MA_SAFE_VELO_STOP_REACTION.
n = 0, 1, 2, 3 stand for the limit value of SG1, SG2, SG3, SG4
When SBH/SG is active in a 1-encoder system, the speed is monitored corresponding to the
encoder limit frequency. An appropriate alarm is output if this limit is exceeded.

MD36963 $MA_SAFE_VELO_STOP_REACTION
$MA_SAFE_VELO_OVR_FACTOR[0...15]
SG correction values
Min. input limit: 1.0
Limit value corrections for safely reduced speeds 2 and 4 can be selected using SGEs and
the associated correction value (percentage value) set using this MD.
n = 0, 1, ... , 15 stand for correction 0, 1, ... 15
Note
● The function "correction, safely reduced speed" is enabled using MD36901
$MA_SAFE_FUNCTION_ENABLE.
● This correction has no effect for the limit values associated with safely reduced speeds 1
and 3.
