8.4 Friction compensation with adaptive characteristics
● "Previous step" softkey to return to the previous feedrate.
● "Data list" softkey to switch to the list of machine data.
● "Cancel" softkey to cancel the recording and reject the entries.
● "OK" softkey to accept the values determined during the friction compensation.

Data list

In the data list, axis machine data and channel setting data are displayed, which are relevant
for "Friction compensation with adaptive characteristics".
The values can be modified before the start. Changes cannot be made while tuning.
To start tuning with fewer than nine steps, overwrite the feedrates that are not required in the
channel setting data MD55822 $SCS_FRICT_OPT_FEED and
MD55823 $SCS_FRICT_OPT_FEED_ROT with zero without any gaps. If, after a feedrate = 0,
a value ≠ 0 is found, then the procedure is canceled.
The following also applies: MD55822[0] ≠ 0 and MD55823[0] ≠ 0
⇒ Further actions:
Softkey "<<" to return to the "Friction compensation" dialog.

Example for a linear axis (automatic tuning)

Requirement
The machine data for activating the friction compensation is set for the Y axis:
● MD32490 = 3
● MD32510 = 1
The Y axis is measured with the following settings:
● Radius 5 mm in SD55820 $SCS_FRICT_OPT_RADIUS
● Feedrates in SD55822[n] $SCS_FRICT_OPT_FEED
● The active time is not adapted.
Result of the Y axis
Step 1 of 8: 700 mm/min
Step 2 of 8: 560 mm/min
Step 3 of 8: 350 mm/min
