Overview of Alarms
NCK alarms
27033 Axis %1 parameterization of MD %2[%3] invalid
Parameters: %1 = Axis number
%2 = MD identifier
%3 = Machine data index
Definitions: The parameterization of machine data %2 is incorrect. An additional indication is the array index of
the machine data. If the machine data is a single machine data, a zero is specified as array index. This
alarm occurs in the following contexts:
- 1. Conversion of the specified MD into the internal calculation format will cause an overflow.
- 2. The values entered in MD $MA_SAFE_POS_LIMIT_PLUS and $MA_SAFE_POS_LIMIT_MINUS
have been interchanged. The upper limit is less than or equal to the lower limit.
- 3. For an axis with safety functions, the setpoint/actual channel assignment in MD
$MA_SAFE_ENC_SEGMENT_NR, MD $MA_CTRLOUT_SEGMENT_NR was not made on the drive
bus. No module number was stated for a setpoint/actual value assignment in MD
$MA_CTRLOUT_MODULE_NR, MD $MA_SAFE_ENC_MODULE_NR.
- 4. The number of drives has changed. On reading back the standstill position and the associated
drive number, a difference has been found to the current drive configuration.
- 5. A safety function has been enabled in MD $MA_SAFE_FUNCTION_ENABLE without the safety
functions SBH/SG having been enabled.
- 6. Error on parameterizing the input/output settings for the SGEs/SGAs.
- 7. A zero has been entered in MD $MA_SAFE_ENC_GRID_POINT_DIST.
- 8. A zero has been entered in MD $MA_SAFE_ENC_RESOL .
- 9. Different settings have been made in MD $MA_IS_ROT_AX and MD $MA_SAFE_IS_ROT_AX.
- 10. A non-existent measuring circuit has been parameterized in MD $MA_SAFE_ENC_INPUT_NR.
- 11. In MD $MA_SAFE_ENC_MODULE_NR, the number of a drive has been entered that either does
not exist or has been detected as inactive. With an inactive drive, MD $MA_SAFE_ENC_TYPE was
not reset to 0.
- 12. In MD $MA_SAFE_ENC_TYPE, an encoder type has been parameterized that does not match
the physically present type.
- 13. In MD $MA_SAFE_ENC_TYPE, an incorrect encoder type has been entered for an active drive
($MA_SAFE_ENC_TYPE = 0, 2, 3 or 5).
- 14. When setting the parameters for the motor encoder in MD $MA_SAFE_ENC_INPUT_NR, the
measuring circuit for the 2nd measuring system is also used to ensure double-redundancy. The 2nd
measuring circuit of this drive module has also been parameterized in the data of another axis,
therefore there is a dual assignment. The 2nd measuring circuit connection cannot be used for the
actual value acquisition in this parameterization.
- 15. In MD $MA_SAFE_POS_TOL a value greater than 10mm was entered for a linear axis.
- 16. In MD $MA_SAFE_REFP_POS_TOL, a value greater than 1mm was entered for a linear axis.
- 17. The limit values for the "n<n_x" monitoring, calculated from MD $MA_SAFE_VELO_X and MD
$MA_SAFE_POS_TOL, are of equal size.
- 18. One of the activated cam positions is outside the actual value modulo range.
- 19. The parameterized cam modulo range MD $MA_SAFE_MODULO_RANGE is not a multiple
integer of 360 degrees.
- 20. The parameterized cam modulo range MD $MA_SAFE_MODULO_RANGE and the modulo
range in MD $MA_MODULO_RANGE cannot be divided as integers into one another.
- 21. The "Actual value synchronization 2-encoder system" function (slippage) is selected for a single-
encoder system, or a function with an absolute reference (SE/SN) is active at the same time.
- 22. Alarms 27000/300950 should be suppressed for parking (MD
$MA_SAFE_PARK_ALARM_SUPPRESS!=0). The SGA "Axis safely referenced" must be configured
in MD $MA_SAFE_REFP_STATUS_OUTPUT.
- 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, bit6) 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 (bit31 = 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 via MD
$MA_ENC_REFP_STATE for the parameterizable incremental encoder, and a monitoring function
with absolute reference (SE/SN) is enabled via 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
