1-356
• 23. An axial SGE/SGA was configured at the SPL interface (segment number = 4) and
the function enable for the external stops (MD $MA_SAFE_FUNCTION_ENABLE, bit 6)
is missing.
• 24. An axial SGE/SGA was parameterized at the SPL interface (segment number = 4)
and the SGE "Deselect ext. Stop A" (assignment via MD
$MA_SAFE_EXT_STOP_INPUT[0]) was parameterized inverted (bit 31 = 1) or the
SGE "Deselect ext. Stop A" was not parameterized at the SPL interface $A_OUTSI.
• 25. The function "Save actual value with incremental encoder" is enabled in MD
$MA_ENC_REFP_STATE for the parameterizable incremental encoder, and a monitor-
ing function with absolute reference (SE/SN) is enabled in MD
$MA_SAFE_FUNCTION_ENABLE. It is not permissible to combine these functions.
• 26. A value greater than 1000 mm/min was entered for a linear axis in MD
$MA_SAFE_STANDSTILL_VELO_TOL.
• 27. A value greater than 20000 mm/min was entered for a linear axis in MD
$MA_SAFE_STOP_VELO_TOL.
• 28. A value greater than 1000 mm/min was entered for a linear axis in MD
$MA_SAFE_VELO_X.
• 29. A value greater than 1000 mm/min was entered for a linear axis in
$MA_SAFE_SLIP_VELO_TOL.
• 30. A value greater than the maximum settable encoder limit frequency for the safe
operation of a single-encoder system was set in MD $MA_SAFE_ENC_FREQ_LIMIT.
• 31. A value greater than 300 kHz for a Performance-1 or Standard-2 control module
was set in MD $MA_SAFE_ENC_FREQ_LIMIT.
• 32. MD $MA_SAFE_EXT_PULSE_ENAB_OUTPUT was not or not correctly parame-
terized. A parameterization of this MD is required if in MD
$MA_SAFE_PULSE_ENABLE_OUTPUT, bit 30 is set to 1, i.e. internal pulse suppres-
sion is being used.
• 33. The MD $MN_SAFE_SPL_STOP_MODE has been parameterized to the value of 4
(Stop E) without having enabled the external Stop E in all the axes with SI function
enables (MD $MA_SAFE_FUNCTION_ENABLE not equal to 0).
• 34. Testing the mechanical system of the brakes was enabled in MD
$MA_FIXED_STOP_MODE (bit 1 = 1), without previously enabling the safe operation
function for this axis in MD $MA_SAFE_FUNCTION_ENABLE. Testing the mechanical
system of the brakes is only admitted with safety functions in this axis.
• 35. Illegal values have been parameterized in MD $MA_SAFE_VELO_STOP_MODE or
MD $MA_SAFE_VELO_STOP_REACTION.
As of SW 6.3, this alarm will also occur when:
• $MA_SAFE_EXT_PULSE_ENABLE_OUTPUT was not or not correctly parameterized.
A parameterization of this MD is required if in MD
$MA_SAFE_PULSE_ENABLE_OUTPUT, bit 30 is set to 1, i.e. internal pulse suppres-
sion is being used.
• A value greater than the maximum settable encoder limit frequency for the safe opera-
tion of a single-encoder system was set in $MA_SAFE_ENC_FREQ_LIMIT.
• A value greater than 300 kHz for a Performance-1 or Standard-2 control module was
set in $MA_SAFE_ENC_FREQ_LIMIT.
• The MD $MN_SAFE_SPL_STOP_MODE has been parameterized to the value of 4
(Stop E) without having enabled the external Stop E in all the axes with SI function
enables ($MA_SAFE_FUNCTION_ENABLE not equal to 0).
