Application

With M143 the control resets a basic rotation as well as a 3D basic rotation, for example after machining a workpiece that needed alignment.

Description of function

Effect

M143 is in effect blockwise and takes effect at the start of the block.

Application example

11 M143

; Reset the basic rotation

In this NC block the control resets a basic rotation that had been defined in the NC program. In the active row of the preset table the control overwrites the values of the columns SPA, SPB, and SPC with the value 0.

Without M143 the basic rotation remains in effect until you manually reset the basic rotation or overwrite it with a new value.
