11.2 NCK safety alarms for SINUMERIK 840D sl
27038 Axis %1 value %2 in drive parameter %3 violates the limits of NCK MD %4
Remedy Investigate, why in the specified drive parameter(s) an incorrect value has been entered (e.g. for internal
software errors in the drive, refer to the drive documentation).
Program con‐ Switch control system OFF and ON again.

27039 Axis %1 parameterization MD %2[%3] was changed, acknowledge and acceptance required
Parameter %1 = axis name, spindle number
%2 = MD name
%3 = MD field index for MD name
Explanation The parameterization for the SI monitoring functions, read out of the drive, does not match the NCK param‐
eterization displayed in the MD. The appropriate NCK-MD was adapted. The following relationship exists
between NCK MDs and drive parameters:
MD36969$ MA_SAFE_BRAKETEST_TORQUE_NORM corresponds to p2003
Response Mode group not ready
Channel not ready
NC start disable in this channel
Interface signals are set
Alarm display
NC stop for alarm
Remedy Continue commissioning, correct checksums.
When displaying MD36969 $MA_SAFE_BRAKETEST_TORQUE_NORM:
Changes to p2003 must be taken into account when parameterizing MD36969 $MA_SAFE_BRAKET‐
EST_TORQUE. The holding torque to be parameterized for the brake test must be reselected:
MD36969 $MA_SAFE_BRAKETEST_TORQUE = required test torque of the brake / p2003 * 100
An acceptance test must then be performed to ensure that the brake test functions correctly.
Program con‐ Switch control system OFF and ON again.
tinuation
27040 Axis %1 waiting for the Motor Module
Parameter %1 = axis name, spindle number
Explanation Alarm when booting as long as the Motor Module is still not ready for SI. When booting, communications to
the Motor Module have still not been established as the safety functions are still not available. MD10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL can be used to set the alarm display so that only one alarm is
displayed for all axes.
