Reaction: Alarm Display; Axis Name, Spindle Number - Siemens Sinumerik 840D sl Diagnostic Manual

Overview of Alarms
NCK alarms
Definitions: The machine data contains an invalid value and therefore has been changed by the software.
Reaction: Alarm display.
Remedy: Check MD.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26025 Axis %1 machine data %2[%3] value changed
Parameters:

%1 = Axis name, spindle number

%2 = String: MD identifier
%3 = Index: MD array index
Definitions: The machine data contains an invalid value. It was therefore changed by the software internally to a
valid value.
Reaction: Alarm display.
Remedy: Check MD.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26026 Axis %1 SINAMICS drive parameter P2038 value is not allowed.
Parameters: %1 = Axis name, spindle number
Definitions: For SINAMICS drives only:
The interface mode, which is set via drive parameter P2038, has not been set to SIMODRIVE 611
universal.
The alarm can be disabled by MD13070 $MN_DRIVE_FUNCTION_MASK - bit15.
However, the following must be noted:
- The device-specific assignment of the bits in the control and status words may be different.
- The drive data sets can be created at will, and need not be subdivided into groups of 8. (For details
see also SINAMICS Commissioning Manual). So the parameters of motors 2-4 may be incorrectly
assigned.
Reaction: NC not ready.
The NC switches to follow-up mode.
Mode group not ready, also effective for single axes
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Set P2038 = 1 or
- Set P0922 = 100...199 or
- Set bit 15 of MD13070 $MN_DRIVE_FUNCTION_MASK (note the boundary conditions, see above)
and execute a Power ON in each case.
Program Con- Switch control OFF - ON.
tinuation:
26030 Axis %1 encoder %2 absolute position lost
Parameters: %1 = Axis name, spindle number
%2 = Encoder number
Definitions: The absolute position of the absolute encoder has become invalid because
- on changing parameter block a changed gear stage ratio was identified between encoder and pro-
cessing or
- the encoder has been replaced (the absolute encoder's serial number has changed, see MD34230
$MA_ENC_SERIAL_NUMBER, and drive-specific parameters).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Axes of this channel must be re-referenced.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
