Operational Overview

Figure 16: Specified Home Offset, Backup Required

End of Home Position

The End of Home Position (End Posn) defines the home position in relation to the machine’s coordinate system. At the

completion of the home, the value of the End of Home Position is put into the command position.

Home Limit Distance

This parameter places an upper limit on the incremental distance the motor will travel during the home.

If no reference is found, the system will decelerate and stop at the limit distance. The Home Limit Distance Hit function will

be activated if the home stops at the limit distance without finding the reference. Additionally, the Home.CommandComplete

function will not turn “On” if the limit distance is hit.

Home Examples

Example 1: Linear Application

In this example, the system uses an external sensor and the motor’s encoder marker channel to establish a Home Reference

Position. This is the most accurate and most common way to home.

Figure 17: Home to Sensor and Marker, Example

When the device sees the Home Initiate, it accelerates the motor to the Home Velocity.
