SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
– The logical basis address configured in HW config and that ad-
dressed via MD $MA_SAFE_CTRLOUT_NR,
$MN_SAFE_DRIVE_LOGIC_ADDRESS do not match or the slot
that is addressed has the incorrect length.
– Cam position $MA_SAFE_CAM_POS_PLUS[n] or
$MA_SAFE_CAM_POS_MINUS[n] has been parameterized too
close to the modulo limit.
– "Safe cams" have been enabled in $MA_SAFE_FUNC-
TION_ENABLE in bits 8 to 15, while the "Safe cam track" function
was enabled at the same time in $MA_SAFE_CAM_ENABLE.
– The assignment of the logical I/O address of this SI telegram of this
drive via $MA_SAFE_DRIVE_LOGIC_ADDRESS does not match
the configured telegram (Step 7).
– Minus cam position $MA_SAFE_CAM_POS_MINUS[n] is greater
than the plus cam position $MA_SAFE_CAM_POS_PLUS[n]. This
is not permitted for the "safe cam track" function.
– The distance between 2 cams on a cam track
($MA_SAFE_CAM_POS_MINUS[n] and
$MA_SAFE_CAM_POS_PLUS[n]) is too short.
– The cam length, i.e. the distance between the plus cam position
($MA_SAFE_CAM_POS_PLUS[n]) and minus cam position
($MA_SAFE_CAM_POS_MINUS[n]) is too short.
– For at least 2 cams enabled in $MA_SAFE_CAM_ENABLE,
identical values have been entered into $MA_SAFE_CAM_TRACK_
ASSIGN[n].
– The value parameterized in $MA_SAFE_CAM_TRACK_ASSIGN[n]
for a cam enabled in $MA_SAFE_CAM_ENABLE is invalid.
– The cam modulo functionality in $MA_SAFE_MODULO_RANGE is
selected but is presently still not supported for the "safe cam track"
function.
