11.1 Brief description
Compensations
For SINUMERIK 802D sl, the following axis-specific compensation functions can be
activated:
● Backlash compensation
● Interpolatory compensation
– LEC (leadscrew error and measuring system error compensation)
– Sag compensation and angularity error compensation
● Following error compensation (speed feedforward control)
These compensation functions can be set for each machine individually with axis-specific
machine data.
Position display
The normal actual-value and setpoint position displays ignore the compensation values and
show the position values of an ideal machine. The compensation values are displayed in the
"System" -> "Service Display" -> "Service Axes" operating area, under "Abs. compens. value
meas. system 1".
11.2 Backlash compensation
Effect
In the case of axes/spindle with indirect measuring systems, mechanical backlash results in
corruption of the traverse path, causing an axis, for example, to travel too much or too little
by the amount of the backlash when the direction of movement is reversed (see following
figure).
Compensation
To compensate for backlash, the axis-specific actual value is corrected by the amount of
backlash every time the axis/spindle changes direction.
This quantity can be entered for each axis/spindle at the commissioning phase in
MD32450 BACKLASH (backlash compensation)
