SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_FUNCTION_ENABLE
Enable safety–related functions
Min. input limit: 0
Protection level: 7/2
The functions for safe operation can be enabled for one axis/spindle using this machine
data.
It is only possible to enable – on an axis–specific basis – as many axes/spindles for safe
operation as have been enabled by the global option.
The more partial functions that are set then the more computing time the safe functions
require.
Bit 0: Enable safely reduced speed, safe operating stop
Bit 1: Enable safe limit switches
Bit 2: Reserved for functions with absolute reference (such as SE/SN)
Bit 3: Enable actual value synchronization, 2–encoder system
Bit 4: Enable external ESR activation (STOP E)
Bit 5: Enable SG correction
Bit 6: Enable the external stop requests/external STOPs
Bit 7: Enable cam synchronization
Bit 8: Enable safe cam, pair 1, cam+
Bit 9: Enable safe cam, pair 1, cam–
Bit 10: Enable safe cam, pair 2, cam+
Bit 11: Enable safe cam, pair 2, cam–
Bit 12: Enable safe cam, pair 3, cam+
Bit 13: Enable safe cam, pair 3, cam–
Bit 14: Enable safe cam, pair 4, cam+
Bit 15: Enable safe cam, pair 4, cam–
– If bit 1 or a higher bit is set, then bit 0 must also be set since the control system
switches to a safe operational stop in response to STOP C, D or E (a parameteriza-
tion alarm 27033 is output if an error is detected).
– If an insufficient number of axes/spindles have been enabled for safe operation using
the global option, then this data may be overwritten with the value 0000 when boot-
ing.
Global option
/FBSI/ see Chapter: 5.5, "Enabling safety–related functions"
$MA_SAFE_IS_ROT_AX
Rotary axis
Min. input limit: –
Protection level: 7/2
This data specifies whether the axis for safe operation is a rotary axis/spindle or linear axis.
= 0: Linear axis
= 1: Rotary axis/spindle
The value set in this MD must be the same as the value set in MD $MA_IS_ROT_AX. If
they are not identical a parameterizing error is displayed.
