SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_VELO_LIMIT[0...3]
Limit value for safely reduced speed
Min. input limit: 0.0
Protection level: 7/2
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 outputs 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 stands 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.
MD36961 $MA_SAFE_VELO_STOP_MODE
MD36963 $MA_SAFE_VELO_STOP_REACTION
$MA_SAFE_VELO_OVR_FACTOR[0...15]
SG selection values
Min. input limit: 1
Protection level: 7/2
Limit value corrections for the 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 stands for correction 0, 1, ... 15
Note
The function "correction, safely reduced speed" is enabled using MD36901
S
$MA_SAFE_FUNCTION_ENABLE.
This correction has no effect for the limit values associated with safely reduced speeds
S
1 and 3.
