5. The first step with the first feedrate of the measurement series is selected. Enter the friction
compensation values in the following entry fields:
Input field Unit Machine data
Amplitude [mm/min]
or [°/min]
MD32571 $MA_FRICT_VELO_STEP
Decay time [s] MD32574 $MA_FRICT_V_PULSE_DECAY_TIME
Active time [s] MD32573 $MA_FRICT_V_PULSE_CONST_TIME

0$B)5,&7B9(/2B67(3
For both traversing directions, as default setting, the same compensation values are
entered. By selecting the option "Set reversal points separately", you can enter different
compensation values for an axis, depending on the particular traversing direction.
6. Press
the
"Next
step"
softkey to start a new measurement with the next feedrate and enter
new values. If the measurement is repeated, the values appropriate for the feedrate from
the last measurement are proposed.
After the last step, the measuring series is terminated with "OK" and the data is saved.
Note
Incremental value change
Use the following shortcut keys to change the compensation values incrementally:
● The selected entry field is activated with the <INSERT> key, and the color changes.
● The values
are
changed
with
different
increments
with
the

keys
and the ↑↓ cursor keys.
● End the input with the <INPUT> key.
⇒ Further actions:
● "Axis +" or "Axis
-" softkey to select the axis for which the friction compensation is activated.
● "Start" softkey to start the measurement.
● "Next step" softkey to select the next feedrate.
