SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
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,
$MN_SAFE_DRIVE_LOGIC_ADDRESS).
Check the assignment of the telegram configuration for the OM slave.
Replace the hardware
Check and ensure that the EMC conditions are complied with.
Clear the alarm with the RESET key. Restart the part program.
Axis %1 encoder evaluation error of the safety–related actual
value
%1 = axis number
The redundantly determined safety–related actual value does not
match the actual value – with fine resolution – of the same encoder.
Alarm display
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
Check the encoder mounting
Check the encoder parameterization
Check the NCK_MD ($MA_SAFE_ENC_IS_LINEAR,
$MA_SAFE_ENC_GRID_POINT_DIST, $MA_SAFE_ENC_RESOL
and the drive parameter field r0979)
Replace the hardware
Check and ensure that the EMC conditions are complied with.
Clear the alarm with the RESET key. Restart the part program.
Axis %1 CRC error of the safety–related actual value
%1 = axis number
When checking the data consistency of the safety–related actual value
(CRC), an error was detected.
Alarm display
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
