Software Setup and Operation
Additionally, the Home Completed output (output function number 9) and End of Home
output, if assigned, will not come on. The Home Limit is disabled when the limit is set to the
default value zero.
Home Cycle Example
An example of a Home cycle can be demonstrated with a ball screw or rack and pinion drive.
This particular application uses most of the programming features in the Home setup. The
drive will first feed to the Home sensor, then feed off the sensor, then go to the resolver zero
position (see Figure 75: "Home Cycle Example of Feed On/Off/Offset" on page 111).
Assume you want the motor to move the table - (towards the motor) until the Home Ø Sensor
is triggered, then move slowly out of the sensor field, and finally rotate to the zero point. The
home sensor in this example is a significant distance from the machine’s actual zero point.
This distance is the value you entered for the Position parameter in the Home setup screen.
The Position parameter lets the FX drive home to the sensor location but operate with respect
to the actual zero point.
