SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
Axis %1 waiting for the Motor Module
%1 = axis name, spindle number
Alarm when booting as long as the Motor Module is still not ready for
SI. When booting, communications to the Motor Module have still not
been established as the safety functions are still not available.
MD $MN_SAFE_ALARM_SUPPRESS_LEVEL can be used to set the
alarm display so that only one alarm is displayed for all axes.
Alarm display
Interface signals are set
The alarm is continuously active when booting if the drive does not
communicate. Otherwise, the alarm is only briefly present and is then
automatically cleared again.
Possible causes that the alarm is permanently present:
– The safety motion monitoring functions are only activated in
$MA_SAFE_FUNCTION_ENABLE, however, not in the correspond-
ing parameter of the associated drive (p9501).
– The axis –> drive assignment via MD
$MA_SAFE_CRTLOUT_MODULE_NR,
$MN_SAFE_DRIVE_LOGIC_ADDRESS or p0978 is incorrect
– PROFIBUS connector fallen out.
The alarm is no longer displayed when the alarm cause has been re-
moved. No other operator actions are required.
Axis %1 failure SI communications
%1 = axis number
Communications with the drive for the Safety Integrated motion moni-
toring functions is additionally monitored. This monitoring function has
detected an error.
Alarm display
Interface signals are set
NC start inhibit in this channel
NC stop for alarm
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
Check the connections between the NCK and drive.
Check the configuring of a PROFIBUS telegram (e.g. SI slot config-
ured).
Check the assignment between the NCK SI axis and SI slot
($MA_SAFE_CTRLOUT_MODULE_NR,
$MN_SAFE_DRIVE_LOGIC_ADDRESS).
