$MA_SAFE_STANDSTILL_TOL
Zero speed tolerance
Min. input limit: 0.
Protection level: 7/2
This MD specifies the tolerance for a safe operating stop.
If the difference between the position limit value and position actual value is greater than
the tolerance set here when a safe operating stop is selected, then the control system out-
puts Alarm 27010 with STOP B. The position limit value is the position actual value at the
instant that a safe operating stop is selected.
MD 36956: $MA_SAFE_PULSE_DISABLE_DELAY
$MA_SAFE_VELO_LIMIT[n]: 0 ... 3
Limit value for safely reduced speed
Min. input limit: –
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
$MA_SAFE_VELO_ST OP_MODE or $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 set in MD $MA_SAFE_ENC_FREQ_LIMIT. An appropriate
alarm is output if this limit is exceeded.
MD 36961: $MA_SAFE_VELO_STOP_MODE
MD 36963: $MA_SAFE_VELO_STOP_REACTION
$MA_SAFE_VELO_OVR_F ACTOR[n]: 0 ... 15
SG selection values
Min. input limit: 1.0
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
S The "Correction for safely reduced speed" function is enabled using MD 36901
$MA_SAFE_FUNCTION_ENABLE.
This correction has no effect for the limit values associated with safely reduced speeds
S
1 and 3.
