MD 36955 $MA_SAFE_STOP_SWITCH_TIME_F[AX1] = 3.5;
3.5 s because ESR was parameterized to 3.1 s
MD 36955 $MA_SAFE_STOP_SWITCH_TIME_F[AX2] = 3.5;
3.5 s because ESR was parameterized to 3.1 s
An ESR can be initiated in this time. This is the reason that here it makes sense
to use the same time as in $MA_ SAFE_STOP_SWITCH_TIME_E.
4.)
MD 10089 $MN_SAFE_PULSE_DIS_TIME_BUS_FAIL[AX1] = 0.5;
0.5 s because ESR was parameterized to 0.2 s
An ESR can be autonomously executed in the drive (drive-based function) in
this time. This time should therefore be adapted to the parameterization of the
drive MD $MD_RETRACT_TIME (in this particular example, 200 ms).
In this example, the system does not wait for this time in the following specific
cases

A value (1 s + retraction time) must be entered, for all axes, in the MD 36951
(delay time SG and SBH). After 1 s, the defective door switch is detected with
Alarm 27090, crosswise data comparison and Stop E is initiated. Depending on
the selected SG stage, retraction motion is executed. If this time is significantly

The safe operating stop is activated after this time has expired.
This is the reason that this transition time for the Stop E must
correspond to the ESR times
($MC_ESR_DELAY_TIME1 + $MC_ESR_DELAY_TIME2). If this
time is selected to be too short, then the retraction motion will not
be correctly executed and depending on the safe functions, hard
stops will be initiated (Alarm 27024 Stop A/B).

active SG1: For SG1, $MA_SAFE_VELO_STOP_REACTION is
parameterized so that when the bus fails, the pulses should be
immediately cancelled.
