Hard-stop homing is a method for homing/referencing the axis to a known absolute position. Hard-stop homing is just like normal home switch based homing but does not require any type of switch. Instead hard-stop homing detects the mechanical end of travel of the axis being homed. This is done by driving axis gently towards end of axis until motion stops due to mechanical block.
Hard-stop homing support
Most of Granite Devicse drives support hard-stop homing as standard feature. In such models, it is possible to configure the maximum torque or force used, motion speed, and detection threshold of home point. It is also possible to enable the search of feedback device index pulse for more accurate homing. Index pulse is searched after mechanical end point has been detected.
Example video of hard-stop homing with VSD-XE drive (and some random motion with absolue positioning).
Key properties
- No switch needed - reduced wiring and increased reliablity
- Very repeatable when done against stiff mechanical stop
- Easy to setup
