Description: In the case of position-dependent temperature compensation, the error curve
characteristic of the temperature-dependent actual-value deviation can often be
approximated by a straight line. This straight line is defined by a reference point
P_0 and a slope tan-ß.
SD43910 $SA_TEMP_COMP_SLOPE defines the slope tan-ß. This slope can be changed by the
PLC user program as a function of the current temperature.
The axis traverses additionally the compensation value calculated for the current
actual position as soon as the position-dependent temperature compensation becomes
active (MD32750 $MA_TEMP_COMP_TYPE = = 2 or 3).
MD32760 $MA_COMP_ADD_VELO_FACTOR limits the maximum angle of slope tan-ß_max of the
error curve. This maximum angle of slope cannot be exceeded.

When SD43910 $SA_TEMP_COMP_SLOPE is greater than tan-ß_max, the slope tan-ß_max is
used
to calculate
the position-dependent temperature compensation value internally. No
alarm is output.
