11.2 NCK safety alarms for SINUMERIK 840D sl
27035 Axis %1 new HW component, acknowledgement and function test required
Remedy If the alarm occurs while commissioning, then the following should be done:
● Acknowledge checksum MD36998 $MA_SAFE_ACT_CHECKSUM[1] (key switch setting 3 or password
must be entered), continue commissioning.
If the alarm occurs after the replacement of an encoder module or DRIVE-CLiQ motor/encoder, then the
following should be done:
● In the Diagnostics operator area, acknowledge the hardware checksum in MD36998
$MA_SAFE_ACT_CHECKSUM[1] via softkey (key switch setting 3 or password must be entered)
● Re-calibration of the actual value encoder
● Checking the SI actual value acquisition: Speeds, traversing direction, absolute position (if required, set
the user agreement)
● Document the new checksum value in MD36998 SAFE_ACT_CHECKSUM[1] and the last entry in the
change history in MD36993 SAFE_CONFIG_CHANGE_DATE[0]
● Document the hardware and software version data of the new component
Program con‐ Switch control system OFF and ON again.

27036 Axis %1 encoder parameterization MD %2[%3] was adapted
Parameter %1 = axis name, spindle number
%2 = MD name
%3 = MD field index for MD name
Explanation The encoder parameterization for the SI monitoring functions, read out of the drive, does not match the NCK
parameterization displayed in the MD. The appropriate NCK-MD was adapted.
Response Mode group not ready
Channel not ready
NC start disable in this channel
Interface signals are set
Alarm display
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 Continue commissioning, correct checksums.
Program con‐ Switch control system OFF and ON again.
tinuation
27037 Axis %1 and %2 with the same PROFIsafe address %3
Parameter %1 = axis name, spindle number
%2 = axis name, spindle number
%3 = PROFIsafe address
Explanation The PROFIsafe address read out from the drive is identical for these two axes.
