Description

P-AXIS-00021	Selection of backlash compensation
Description	The selection of backlash compensation is done using this parameter. The type of backlash (the backlash between the table and the drive or the backlash between the drive and the measuring system) depends on the mathematical sign of P-AXIS-00103 (getriebe[i].lose).
Parameter	lr_param.anwahl_losekomp
Data type	UNS16
Data range	0: No backlash compensation 1: Last axis motion occurred in pos. direction. 2: Last axis motion occurred in neg. direction.
Axis types	T, R, S
Dimension	T: ----	R,S: ----
Default value	0
drive types.	----

P-AXIS-00103	Size of backlash
Description	The parameter defines the size of backlash.
Parameter	getriebe[i].lose
Data type	SGN16
Data range	SGN16 range 0 < backlash: backlash betw. drive and slide 0 > backlash : backlash betw. slide and measuring system
Axis types	T, R, S
Dimension	T: 0.1µm	R,S: 0.0001 °
Default value	0
Drive types	----

P-AXIS-00243	Distribution of the backlash on multiple cycles
Description	The parameter defines a number of position control cycles on which the backlash is distributed. The distribution is done according to a sin² function. The parameter is also used for bi-directional lead screw error compensation if a change of direction is executed.
Parameter	lr_param.n_backlash_cyc
Data type	UNS16
Data range	0 < n_backlash_cyc < 20
Axis types	T, R, S
Dimension	T: Number of interpolation cycles	R,S: Number of interpolation cycles
Default value	0
Drive types	----
Remarks	For the values 0 or 1 the output of the backlash to the drive is done abruptly within one cycle. A value larger than 1 creates a distribution according to the sin²function The use of this feature avoids increasing errors at the workpiece, because for large backlash the machine excitation is reduced.
