DvTmax = MD32000 $MA_MAX_AX_VELO * MD32760 $MA_COMP_ADD_VELO_FACTOR
Example: MD32000 $MA_MAX_AX_VELO = 10 000 [mm/min]
3.
4.
With larger values of SD43910 $SA_TEMP_COMP_SLOPE, the maximum gradient (here 0.57
degrees) for the position-dependent temperature compensation value is used internally.
There is no alarm.
Note:
Any additional excessive velocity resulting from temperature compensation must be
taken into account when defining the limit value for velocity monitoring (MD36200
$MA_AX_VELO_LIMIT).
MD irrelevant for:
MD32750 $MA_TEMP_COMP_TYPE = 0, sag compensation, LEC, backlash compensation
