SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
Axis %1 acceptance test mode is active
%1 = axis number
An SI acceptance test has been started with the acceptance test wiz-
ard at the operator panel. The acceptance test mode is activated for
the NCK and drive for the duration of this acceptance test. In the ac-
ceptance test mode, SI power on alarms can be acknowledged with the
reset key.
Alarm display
Deselect the acceptance test, e.g. using the acceptance test Wizard or wait
until it has been completed (the duration of the acceptance test can be para-
meterized using MD $MA_SAFE_ACCEPTANCE_TST_TIMEOUT).
The alarm is no longer displayed when the alarm cause has been re-
moved. No other operator actions are required.
Axis %1 SW limit switch deactivated
%1 = axis number
An SI acceptance test "safe limit positions" has been started with the
acceptance test wizard at the operator panel. For these acceptance
tests, the single–channel SW limit switches are deactivated for the
axis/spindle in order to ensure that the safe limit positions can be ap-
proached.
Alarm display
Deselect the acceptance test, e.g. using the acceptance test Wizard or
wait for the end of the test.
The alarm is no longer displayed when the alarm cause has been re-
moved. No other operator actions are required.
Axis %1 tolerance for safe operating stop exceeded
%1 = axis number
The axis has moved too far away from the reference position. It has
moved farther away than permitted in MD $MA_SAFE_STAND-
STILL_TOL. The alarm can be re–configured in the MD
$MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Stop the axis with speed setpoint = 0 (STOP B). As soon as the speed
actual value is less than that defined in the MD $MA_SAFE_STAND-
STILL_VELO_TOL, at the latest however, after the time in MD
$MA_SAFE_PULSE_DISABLE_DELAY expires, the pulses are can-
celled (STOP A).
