3.4.8 Homing
Determination of the mechanical reference point for measuring systems.
After homing, the drive is in a defined position.
Functions
l Homing ( 3−46)
l Homing end ( 3−47)
l Homing status ( 3−48)
l Homing modes ( 3−49)ff.
l Second homing speed ( 3−56)
l Set homing value( 3−57)
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.
