SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
Wait for Motor Module for at least one axis
Alarm when booting as long as the Motor Module of at least one axis is
still not ready for SI. When booting, communications to the Motor Mod-
ule have still not been established as the safety functions for at least
one axis are still not available.
The alarm display can be set in MD $MN_SAFE_ALARM_SUP-
PRESS_LEVEL (MD < 3) in such a way that it can be individually dis-
played as to whether communications have already been established
for each axis.
Alarm display
Interface signals are set
The alarm is continuously active when booting if at least one 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_CTRLOUT_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.
PROFIsafe: Cycle time %1 [ms] is too long
%1 = parameterized cycle time
The PROFIsafe communication cycle time resulting from MD
$MN_PROFISAFE_IPO_TIME_RATIO and $MN_IPO_CYCLE_TIME
exceeds the permissible limit value of 25 ms.
Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set

NC stop for alarm
Correct the cycle time.
The alarm is initiated when booting if parameterized too long. No pro-
gram can be started. Only delete the alarm with a power on.
