Explanation:
Because a change in the gear ratio has an effect on the retraction path traveled by the drive, no changes may be made
to the gear ratio during the following periods of time:
- Between the last programming of the retraction path with ESRR and the ESR enable
- As from ESR enable
The following machine data define the gear ratios of an axis
MD31050 $MA_DRIVE_AX_RATIO_DENOM
MD31060 $MA_DRIVE_AX_RATIO_NUMERA
MD31064 $MA_DRIVE_AX_RATIO2_DENOM
MD31066 $MA_DRIVE_AX_RATIO2_NUMERA
The gear ratio must not be changed during the periods of time described above, e.g. by changing the parameter set.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
If ESR enable is missing:
- Change the gear ratio before programming the retraction path with ESRR
or
- Reprogram the retraction path with ESRR after changing the gear ratio
Then re-enable ESR.

continuation:
Clear alarm with the RESET key. Restart part program

Axis %1 clamping monitoring
Parameters:
%1 = Axis name, spindle number
Explanation:
The clamped axis has been pushed out of its setpoint position. The permissible difference is defined in the axis-specific
MD36050 $MA_CLAMP_POS_TOL.
Clamping an axis is activated with the axis-specific interface signal DB380x DBX2.3 (Clamping process active).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction:
Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy:
Determine the position deviation to the setpoint position and, depending on the results, either increase the permissible
tolerance in the MD or mechanically improve the clamping (e.g. increase clamping pressure).
Programm
continuation:
Restart part program. Clear alarm with the RESET key in all channels of this mode group. Restart part program.

Axis %1 parameterization error: friction compensation
Parameters:
%1 = Axis name, spindle number
Explanation:
The parameterization of the adaptation characteristic in the quadrant error compensation is not allowed because
acceleration value 2 (MD32560 $MA_FRICT_COMP_ACCEL2 is not between acceleration value 1 (MD32550
$MA_FRICT_COMP_ACCEL1) and acceleration value 3 (MD32570 $MA_FRICT_COMP_ACCEL3).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
