Machine data
2.4 Axis-specific machine data
Description: In sag compensation, the absolute value of the total compensation value (sum
of compensation values of all active compensation relations) is monitored
axially with machine data value CEC_MAX_SUM.
If the determined total compensation value is larger than the maximum value,
alarm 20124 is triggered. Program processing is not interrupted. The compen-
sation value output as the additional setpoint is limited to the maximum
value.
MD irrelevant to:
• MSEC
• Backlash compensation
• Temperature compensation

Description: In sag compensation, modification of the total compensation value (sum of the
compensation values of all active compensation relations) is limited axially.
The maximum change value is defined in this machine data as a percentage of
MD32000 $MA_MAX_AX_VELO (maximum axis velocity).
If the change in the total compensation value is greater than the maximum
value, alarm 20125 is output. Program processing is however continued. The
path not covered because of the limitation is made up as soon as the compen-
sation value is no longer subject to limitation.
