Description of function
The function is selected by a "1" signal of c2597 (Homing type selection) and is activated by a 0/1
edge of c2595 (Homing start). The signal of c2595 must be set during the entire homing
process; otherwise, the process is aborted.
Status bit r2684.1 (passive homing active) is linked with activate measuring probe
evaluation. It activates measuring probe evaluation. c2510 (measuring probe evaluation
selection) and c2511 (measuring probe evaluation edge) can be used to check which
measuring probe (1 or 2) and which measuring edge (0/1 or 1/0) is used.
The probe pulse is used to supply the measured value determined by the function "homing
mark search" and "measuring probe evaluation" via parameter r2523. The validity of the
measurement is reported via r2526.2.
Note
The "Pas
sive homing" function is superimposed on an active operating mode, it is therefore not
an active mode. In contrast to the home position approach, the function can be carried out
superimposed by the machine process.
As standard, for passive homing, measuring probe evaluation is used; when enabled, the
measuring probe is selected and the measuring probe edge evaluation is active. (In the default
settings, measuring probe 1 is always the measuring probe and the measuring probe evaluation
is always the 0/1 edge.)
10.6.4.4 Absolute encoder adjustment
Overvie
w
The function is only available when using a motor with the absolute encoder. When
commissioning the absolute encoder for the rst time, a mechanical axis position is aligned with
the encoder absolute position and then the system is synchronized.
After the drive has been switched o the encoder position information is retained. This
means that the axis does not have to be readjusted when the drive powers up.
Note
It is crucial that absolute encoder
s are adjusted the rst time that they are commissioned.
Description of function
For t
he absolute encoder adjustment, the machine axis must be moved to the desired position
rst, this can be done in jog mode or manually. A position marking, a xed stop, or measuring
the distance between the axis and the xed home position can be used as a reference. Once the
desired position of the axis is reached, the home position coordinate can be set accordingly. You
must save the settings in the device.
The absolute encoder adjustment can also be used with the active homing. For this purpose,
you must select the option during active homing.
