Homing mode
After the initialization, a
homing
(also called
indexation
) has to be carried out, moving the motor until it
reaches a fix reference mark called
index
. The motor movement can highly vary during a homing according to
the type of encoder used. Some display several indexes at regular distance from each other which enable the
user to know the motor absolute position (multi-index encoder) and others display only one (mono-index
encoder). Finally some encoders have no indexes, and homing has to be done against a fix
mechanical end
stop
or against a
limit-switch
or
home switch
. The homing procedure has a double aim: first, to determine
the motor absolute position, and secondly, to find a constant phase shift adjustment value for each system set
up.
• You will have to select, with the black arrows, the correct options in three scroll menus on the window:
• Choose against which kind of reference should be performed the homing (depends on your hardware):
• Choose the movement direction for the homing and say if a limit switch is present or not:
• Four parameters (K40, 41, 42, 43) automatically defined by ETT are also displayed.
The parameters values depend on both the encoder and the homing mode you have selected.
It is possible to modify K41, 42, 43.
Never modify these values unless you are an experienced user!
• Click on the
NEXT
button and the next window will appear.
