• 1. The conversion of the specified MD into the internal calculation format leads to over-
flow.
• 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 value 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 momentary drive configu-
ration.
• 5. A safety function has been enabled in MD $MA_SAFE_FUNCTION_ENABLE with-
out 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. In MD $MA_IS_ROT_AX and MD $MA_SAFE_IS_ROT_AX , differing settings were
made.
• 10. A measuring circuit that does not exist was parameterized in MD
$MA_SAFE_ENC_INPUT_NR.
• 11. In MD $MA_SAFE_ENC_MODULE_NR, the number of a drive has been entered
which 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 was parameterized which does
not match the physically present type.
• 13. In MD $MA_SAFE_ENC_TYPE, an incorrect encoder type was entered for an
active drive ($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 10 mm 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.
