Setting the reference point for absolute measurement Sinumerik 840D.

For homing axes with absolute encoder, it is necessary to set:

-axis Data-parameter 34210 to 1

-enter the desired value of the axis position in the parameter 34100

-select the mode of homing

-choose the axis that we want to homing-press the directional button +

The axis make homing, parameter 34210 is automatically overwritten to 2 (number 2 means that the axis is adjust) and the reference position of the axis from parameter 34100 is overridden. (For example, if we want to have a 200 axis position in the 34100 parameter, we write a value of 200).
