PLCopen Homing Description

The homing features provided in PLCopenA vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML create tools for homing of PLCopen axes. HomingThe Homing procedure allows, based on a position measurement, to set a position offset to the motor in order to ensure it is physically at the home position may be performed utilizing the MC_Reference function block, utilizing Custom Homing Library UDFB"User Defined Function Block" UDFB can be used as a sub-function block in another program of the application. It is described using FBD, LD, ST or IL language. Input / output parameters of a UDFB (as well as private variables) are declared in the variable editor as local variables of the UDFB’s or by writing your own homing cycles.

• Utilizing MC_Reference
  The application specifies a position for an axis to be assigned to a reference position, then invokes the MC_Reference function block to generate motion to move the axis to the reference location. The AKD capture engine (previously set up by the application via SDO commands) captures the position of the reference location. Based on the desired reference position and the captured actual position, the coordinate system is shifted to correlate the desired reference position to this location.
• Writing your own homing cycles
  UDFBs can be written to provide specific "canned" homing cycles based on feedback type, and desired homing sequences such as homing off of limit switches, encoder markers, homing to “zero” or null positions etc. by proper configuration of the AKD capture engine, the MC_Reference and MC_SetPos function blocks.
• Utilizing Custom Libraries
  A library already contains a set of homing UDFB. Contact the Support for more information.
  To add the library to your project, refer to Create and Use Custom Libraries
