SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
– $MN_SAFE_SPL_STOP_MODE
Value 4 (Stop E) was parameterized without the external Stop E
having been enabled in all axes where the SI function was enabled
(MD $MA_SAFE_FUNCTION_ENABLE not equal to 0).
Remedy: Parameterize $MN_SAFE_SPL_STOP_MODE to another
stop or in the specified axes, enable the external stop E (set bits 4
and 6 in $MA_SAFE_FUNCTION_ENABLE).
– $MA_SAFE_DRIVE_PS_ADDRESS
An invalid value (drive parameter p9810 is saved there when boot-
ing) was read or the same address was assigned to several axes.
– $MA_SAFE_ENC_PULSE_SHIFT
It was not possible to internally pre–assign from the drive parame-
terization as the values must have been entered outside the permis-
sible range. Adapt the encoder parameterization in the drive.
– $MA_SAFE_VELO_OVR_FACTOR
It was parameterized with decimal places.
– $MA_SAFE_POS_LIMIT_PLUS/$MA_SAFE_POS_LIMIT_MINUS –
the entered values have been interchanged. The upper limit is less
than or equal to the lower limit.
– $MA_IS_ROT_AX/$MA_SAFE_IS_ROT_AX
Different settings were made in both MD.
– The limit values for the "n<n_x" monitoring function, calculated from
MD $MA_SAFE_VELO_X and MD $MA_SAFE_POS_TOL are the
same magnitude.
– The parameterized cam modulo range MD $MA_SAFE_MO-
DULO_RANGE and the modulo range in MD $MA_MODULO_RANGE
cannot be divided by one another to result in an integral number.
– The mechanical brake system test was enabled in MD
$MA_FIXED_STOP_MODE (bit 1 = 1), without safe operation hav-
ing been enabled for this axis in MD $MA_SAFE_FUNC-
TION_ENABLE. The mechanical brake system test is only permissi-
ble in this axis with safety functions.
– An illegal value was parameterized in MD
$MA_SAFE_VELO_STOP_MODE or MD
$MA_SAFE_VELO_STOP_REACTION.
– The function "Save actual value with incremental encoder" is en-
abled in MD $MA_ENC_REFP_STATE for the parameterizable in-
cremental encoder, and a monitoring function with absolute refer-
ence (SE/SN) is enabled in MD $MA_SAFE_FUNCTION_ENABLE.
This combination of functions is not permitted.
– The alarms 27000/C01797 should be suppressed when parking
(MD $MA_SAFE_PARK_ALARM_SUPPRESS1=0). In this case,
the SGA "axis safely referenced" must be parameterized using the
MD $MA_SAFE_REFP_STATUS_OUTPUT.
