27040 Axis %1 waiting for the Motor Module
Remedy The alarm is continuously active when booting if the drive does not communicate. Otherwise, the alarm is
only briefly active - and is then automatically cleared again. Possible causes for the alarm being permanently
present:
● The safety motion monitoring functions are only activated in MD36901
$MA_SAFE_FUNCTION_ENABLE, however, not in the corresponding parameter of the associated drive
(p9501).
● The assignment axis → drive via MD36906 $MA_SAFE_CRTLOUT_MODULE_NR, MD10393
$MN_SAFE_DRIVE_LOGIC_ADDRESS or p0978 is incorrect.
● PROFIBUS connector fallen out.
Program con‐ The alarm is no longer displayed when the alarm cause has been removed. No other operator actions are
tinuation required.
27050 Axis %1 failure SI communications
Parameter %1 = axis name, spindle number
Explanation Communications with the drive for the Safety Integrated motion monitoring functions is additionally monitored.
This monitoring function has detected an error.
Response Alarm display
Interface signals are set
NC start disable in this channel
NC stop for alarm
In addition, a STOP F is initiated, that can result in the subsequent Alarm 27001 with fault IDs 0, 27023 and
27024. Alarm 27001 with fault ID 0 can be prevented using the alarm reduction (MD10094
$MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
Remedy Check the connections between the NCK and drive.
Check the configuring of the PROFIBUS telegram (e.g. SI slot configured).
Check the assignment between the NCK SI axis and SI slot (MD36906 $MA_SAFE_CTRLOUT_MOD‐
ULE_NR, MD10393 $MN_SAFE_DRIVE_LOGIC_ADDRESS).
Check the assignment of the telegram configuration for the slave OM
Check and ensure that the EMC directives are complied with.
Program con‐ Clear the alarm with the RESET key. Restart the part program.

27060 Axis %1 checksum error, drive assignment, acknowledgement and acceptance test required!
Parameter %1 = axis name, spindle number
Explanation The axis-specific MD $MA_SAFE... and MD10393 $MN_SAFE_DRIVE_LOGIC_ADDRESS are protected by
a checksum. The alarm indicates that the actual checksum no longer matches the saved checksum, i.e. that
either a piece of data was illegally changed or is corrupt.
In the commissioning phase (SPL commissioning mode active), instead of the individual axis-specific check‐
sum alarms (27032, 27035 and 27060), the axis-specific group alarm 27132 is displayed. MD10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL can be used to further reduce the alarm display so that only one
alarm is displayed for all axes (global group alarm 27135).
