SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
Check the interface of the safety--related input signals (SPL para-
meterization, PLC--DB supply).
Clear the alarm with the RESET key. Restart the part program.
Axis %1 error for crosswise data comparison: steady- -state
actual value difference
%1 = axis name, spindle number
A difference in the actual values was detected using the crosswise data
comparison between NCK and drive monitoring channel. This differ-
ence is greater than the maximum tolerance defined in MD36942
$MA_SAFE_POS_TOL. This can be checked using the safe position
actual values of the two monitoring channels displayed in the service
screen.
The alarm is only displayed, if monitoring with absolute reference
(SE/SN) has been enabled for the specified axis and if the user agree-
ment has been set. As soon as the user agreement is deleted or the
actual difference between the two monitoring channels again drops
below the maximum permissible difference, the alarm is cleared.
Alarm display
The user agreement must be deleted if the alarm is present as a
steady--state alarm. When the control is then rebooted, the machine
can be brought into the safe state again and operation resumed by a
new referencing process and setting the user agreement.
Prior to setting the user agreement, the actual position of the axis dis-
played in the "User enable" screen must be compared with the current
machine position. This is absolutely necessary to ensure proper func-
tioning of the safe limit positions (SE) and safe cams (SN).
The user agreement can only be changed in key--actuated switch
setting 3 or after entering a password.
The alarm is no longer displayed when the alarm cause has been
removed. No other operator actions are required.
Axis %1 acceptance test mode is active
%1 = axis name, spindle number
An SI acceptance test has been started with the acceptance test
wizard at the operator panel. The acceptance test mode is activated for
the NCK and drive for the duration of this acceptance test. In the
acceptance test mode, SI power on alarms can be acknowledged with
the reset key.
Alarm display, on the NCK side, the alarm criterion of SI--POWER ON
alarms is changed over to reset--acknowledgeable.
