Setting Up Parameters
Acceleration
This parameter specifies the acceleration value to be used during the home. The acceleration units are defined by the Time Scale parameter on the User Units view.
Deceleration
This parameter specifies the deceleration value to be used during the home. The deceleration units are defined by the Time Scale parameter on the User Units view.
If on sensor ... Group
Back off before homing Option Button
The Back off before homing flag effects the drive’s behavior when the home sensor is active at the time the home is initiated. If the flag is set, the drive will back off the sensor. It does this by moving the opposite direction to that specified by the sign of the home velocity. It continues moving in this direction until the sensor deactivates. It then decelerates to a stop and performs a standard home.
Go forward to next sensor Option Button
The Go forward to next sensor flag effects the drive’s behavior when the home sensor is active at the time the home is initiated. If the flag is set, the drive will go forward to the next sensor. It does this by performing a standard home routine looking for the rising edge of the home sensor.
Home Offset Group
Calculated Offset Option Button
The calculated offset is defined as the distance travelled during deceleration ramp from the home velocity to a stop plus the distance travelled at the home velocity for 400µs. This extra distance is used to guarantee that the motor will not need to backup after the deceleration ramp.
Specified Offset Option Button
The specified offset allows the user to choose an exact offset from the Home Reference.
Home Limit Distance Enable Check Box
The “Home Limit Distance Enable” check box enables the Home Limit Distance parameter. If this flag is not set, there is no limit to the distance the drive will travel during a home routine.
Limit Distance
This parameter places an upper limit on the distance the motor will travel during the home. In situations where the reference position indicator (sensor or marker) is not seen, this parameter limits the total distance the motor will move.
End of Home Position
The “End of Home Position” designates the absolute position of the home in the machine coordinate system. At the completion of the home cycle, the End of Home Position value is put into the command and feedback positions. At the completion of the home cycle, the Absolute Position will have the value entered for this parameter. This value is in motor revolutions.
