Homing Based on Home Sensor (with dog to be re-detected)(No. 645.0=2, No. 645.3=1)
This operation indicates the type of homing based on the home position sensor.
another detection of the dog-front-end after the first detection
You can use this homing type to set the point of machine passing the dog as the home base. Re-detection of
the dog improves the accuracy in setting the home position.
There are three options for what to be set as "home" (after detection of passing-dog position): 1) dog position,
2) encoder z-phase, 3) any position shifted from dog or z-phase.
Set the following parameters related to this homing method.
*) Parameters to define the homing patterns.
Refer to the patterns 19 to 24 to configure the parameters.
