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 Switch control OFF - ON.
Continuation:
26027 Axis %1 Stiffness mode Splines is not available (%2)
Parameters: %1 = Axis name, spindle number
%2 = Fine ID
Definitions: The Stiffness mode Splines is not available.
Fine coding:
Bit 0 - SINAMICS function block is not present (see P0108)
Bit 1 - $MN_DRIVE_TELEGRAMM_TYPE, set telegram that supports splines functionality (e.g. telegram 136)
Bit 2 - Set $MA_VELO_FFW_WEIGHT = 100%
Bit 3 - Set $MA_FIPO_TYPE = 2
Bit 4 - Set $MA_FFW_MODE = 3 or 4
Bit 5 - Set $MN_POSCTRL_SYSCLOCK_TIME_RATIO = 1
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 $MA_SPLINES_CONTROL_CONFIG=0, or note and implement fine error code.
Program Switch control OFF - ON.
Continuation:
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 processing 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.
Remedy: Please inform the authorized personnel/service department. Rereferencing/resynchronization of the absolute
encoder; attach absolute encoder on the load side and configure correctly (e.g. MD 31040 $MA_ENC_IS_DIRECT).
Program Restart part program.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
26040 Axis %1 encoder parameterization MD %2[%3] has been adjusted.
Parameters: %1 = Axis number
%2 = MD identifier
%3 = Machine data index
