The particulars of backlash compensation can be defined with MD52 and MD53.
MD Function Value/Description Unit
52 Speed for backlash
compensation
0
Backlash traversing speed 1 % of MD23
1 to 1 00
Backlash traversing speed in % of MD23 [%]
53 Mode for backlash
compensation
0= Backlash compensation prior to positioning
1= Backlash compensation during positioning
The backlash traversing speed is added to the
programmed speed for the traversing
job affected by override.

Note the following carefully:
S If the interdependencies of the MDs are violated, an error is reported with
“range violation” as its cause.
S Backlash compensation goes into effect prior to reference point approach.
S A change in MD30 (backlash) takes effect only after a traversing movement in a
backlash-free direction (MD31).
S Backlash travel is started only if override > 0.
