Friction Compensation - Automatic Tuning - Siemens SINUMERIK 840D sl Commissioning Manual

NC commissioning
8.4 Friction compensation with adaptive characteristics
Commissioning archive:
The tuning results in the axis machine data and also the tuning status of the axes are backed
up in the "NC data" commissioning archive. If the commissioning archive with the tuning data
from machine A is read into machine B, then the NC data are completely read in.
● The axis machine data is read in and becomes effective.
● The axis tuning status is read in. Only when selecting the "Friction compensation" dialog, as
a result of the different serial numbers of the system CompactFlash card, you will be
prompted to accept or reject the tuning status.
General conditions for the commissioning sequence:
● For a feed override not equal to 100 %, the selected axis traverses with the reduced feed.
The tuning (automatic and manual) is held, and the circular representation is suppressed
until the feed override has been again set to 100%.
● The computational resolution in MD10200 $MN_INT_INCR_PER_MM and
MD10210 $MN_INT_INCR_PER_DEG must be at least 10000.
● Tuning is not started if, for the selected axes, the following machine data cannot have a
value of 0:
MD32450 $MA_BACKLASH
MD32456 $MA_BACKLASH_DYN
MD32572 $MA_FRICT_V_PULSE_DELAY_TIME
MD32575 $MA_FRICT_V_PULSE_SMOOTH_TIME
MD32578 $MA_FRICT_T_PULSE_SMOOTH_TIME
MD32579 $MA_FRICT_PRETRIGGER_TIME
Manual tuning:
To start manual tuning press the "Manual tuning" softkey. In the next dialog, select the axes
that you wish to tune.
After completing tuning for an axis in the channel, the compensation values are written to the
axis machine data and the status display updated.
⇒ Further actions:
● "Start" softkey to start automatic friction compensation.
● "Manual tuning >" softkey, to start friction compensation with manual input of the
compensation values.
● "OK" softkey to confirm your selection.
● "Cancel" softkey to cancel the selection.

Operation on the SINUMERIK Operate
The axes selected in the particular channel are automatically traversed individually one after
the other.
