3.4.8.1 Homing

Purpose

Definition of the reference point in the absolute or relative positioning mode.

Function

l Selection of a sequence suitable for homing ( 3−49).

l Setting of the homing speed under C1242

– Setting of a second homing speed under C1241 (if necessary) ( 3−56)

l Setting of the homing acceleration under C1251

l Definition of the final homing point under C1209.

l Execution of homing in

– Manual operation via "manual referencing" ( 3−67).

– Program operation (GDC dialog "Programming" under PS mode" or selection under

C1311/x=3, program set mode)

Homing procedure

l The homing status POS−REF−OK is reset (see ( 3−48)) and the current reference offset

initialised using the value entered under C1225.

l Homing is started and carried out according to the mode selected under C1213.

l If the reference point is found, the home position (C1227) is set and the reference offset

(C1225) is added. The position data now refer to the real zero point (see Fig. 3−12).

l The homing status POS−REF−OK is set.
