The following example clearly indicates the problems when grouping axes
whose terminal 663 is controlled using a digital output:
The 3 X, Y and Z axes have the same parameterized behavior in their SG
stages when the drive bus fails: For SG1, the pulses should be immediately
canceled with the drive bus fails, however, for SG2 to SG4, with a delay.
Terminal 663 is controlled from all 3 drives via the same output (local output on
the NCU). When the bus fails, a 500 ms delay should first expire before the
pulses are cancelled. This is parameterized as follows:
$MN_SAFE_PULSE_DIS_TIME_BUSFAIL = 0.5
; Parameterization for the X axis (AX1):
; STOP D is initiated when the SG is exceeded in SG stages 1 and 2, STOP C
; in SG stages 3 and 4
$MA_SAFE_VELO_STOP_MODE[AX1] = 5; =>
$MA_SAFE_VELO_STOP_REACTION becomes effective
$MA_SAFE_VELO_STOP_REACTION[0, AX1] = 3 ; SG stage 1
$MA_SAFE_VELO_STOP_REACTION[1, AX1] = 13 ; SG stage 2
$MA_SAFE_VELO_STOP_REACTION[2, AX1] = 12 ; SG stage 3
$MA_SAFE_VELO_STOP_REACTION[3, AX1] = 12 ; SG stage 4
