27038 Axis %1 value %2 in drive parameter %3 violates the limits of NCK MD
%4.
Parameters: %1 = Axis number
%2 = Value in drive parameter
%3 = Drive parameter number, for example parameter 979.
%4 = NCK machine data name.
Definitions: A SINAMICS drive delivers values in a parameter that violate the min/max value for an NCK machine
data.
Reaction: Alarm display.
Remedy: Examine why incorrect values are entered in parameter 979 of the drive (for example, internal
software errors in the drive, see drive documentation).
Program Switch control OFF - ON.
Continuation:
27040 Axis %1 waiting for motor module.
Parameters: %1 = Axis name, spindle number
Definitions: Alarm on ramp-up as long as the motor module is not yet ready for SI.
Communication to the motor module is not yet active on ramp-up, the safety functions are not yet
available.
Reaction: Interface signals are set.
Alarm display.
Remedy: The alarm will remain present during ramp-up if the drive does not communicate (for example if the
PROFIBUS plug has fallen out). Otherwise, the alarm will only briefly be displayed and then be deleted
automatically.
Possible causes for the continual presence of this alarm:
The safe motion monitoring is only activated in $MA_SAFE_FUNCTION_ENABLE, but not in the
corresponding parameter of the assigned drive (p9501). Check the correctness of parameter p9501
and the assignment of the drive in MD $MA_SAFE_CTRLOUT_MODULE_NR and
$MN_SAFE_DRIVE_LOGIC_ADDRESS, p0978.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
27050 Axis %1 SI communication failure.
Parameters: %1 = Axis number
Definitions: Communication with the drive for Safety Integrated
motion monitoring is additionally monitored. This monitoring
has found an error.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Verification of the connections between NCK and drive.
Check for compliance with the EMC requirements.
Program Clear alarm with the RESET key. Restart part program
