SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

26020 Axis %1 encoder %2 hardware fault %3 during encoder initialization

Parameters: %1 = axis name, spindle number

%2 = encoder number

%3 = error fine coding

Definitions: Error during initialization or while accessing encoder (refer to additional information for absolute

encoder interface from error fine coding).

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.

Remedy: Please inform the authorized personnel/service department.

Rectify hardware error, replace encoder if necessary.

Program Con-

tinuation:

Switch control OFF - ON.

26022 Axis %1 encoder %2 measurement with simulated encoder not possible

Parameters: %1 = NC axis number

%2 = encoder number

Definitions: Alarm occurs on the control when a measurement is made without the encoder hardware (simulated

encoder).

Reaction: Local alarm reaction.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department.

If possible, modify the measuring motion in such a manner that the axis concerned does not have to

travel; do not program this axis in the MEAS block again. However, it is then no longer possible to

query a measured value for this axis.

Ensure that measurement is not taking place with simulated encoders (MD 30240 ENC_TYPE).

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

26024 Axis %1 machine data %2 value changed

Parameters: %1 = axis name, spindle number

%2 = string: MD identifier

Definitions: The machine data contains an invalid value. This has therefore been changed by the software.

Reaction: Alarm display.

Remedy: Check MD.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 has therefore been changed internally by the software

to a valid value.

Reaction: Alarm display.

Remedy: Check MD.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program
