Example
Effects of various parameter sets with backlash compensation:
MD32450 $MA_BACKLASH[AX1] = 0.01
MD32452 $MA_BACKLASH_FACTOR[0,AX1] = 1.0 Parameter set 1
MD32452 $MA_BACKLASH_FACTOR[1,AX1] = 2.0 Parameter set 2
MD32452 $MA_BACKLASH_FACTOR[2,AX1] = 3.0 Parameter set 3
MD32452 $MA_BACKLASH_FACTOR[3,AX1] = 4.0 Parameter set 4
MD32452 $MA_BACKLASH_FACTOR[4,AX1] = 5.0 Parameter set 5
MD32452 $MA_BACKLASH_FACTOR[5,AX1] = 6.0 Parameter set 6
In parameter set 1 (index 0) of the first axis (AX1), a backlash compensation factor with the
value 1.0 has the following effect:
1.0 * MD32450 = 0.01 mm (or inch or degrees)
The backlash compensation is twice as large in parameter set 2, three times as large in
parameter set 3, etc.
The maximum value is 100.
Supplementary conditions
The functional expansion is available for all control variants.
Control response on POWER ON, RESET, REPOS
The new or modified data are activated via the "Enable machine data" soft key or by a
RESET or POWER ON. Mode switchover, block search or REPOS have no influence.
