OVERVIEW
The following describes the setup required for tube-nut tool operation. This includes determining the values for tube-nut spe-
cific TID parameters (parameters residing in the tool memory) and iEC Controller parameters.

The tube nut TID parameters can be viewed and modified from the Tool-> Edit->Tool Setup screen in ToolWare. The tool to be
configured must be connected to the controller.
Home Detection Torque - Home (in*Lb)
•
When the tool is homing, reaching this torque indicates to the controller the tool output socket has reached the home
stop and is in the open position.
•
If the tool output does not attempt to return or does not completely reach the home position, this value is too low.
•
Attention: Setting this value too high can potentially damage the tool.
•
Units: lbf-in
•
TID memory location: 53
Hold at Home Torque - Open Loop (in*Lb)
•
After reaching the home position, this torque is applied against the home stop to prevent the socket from bouncing to a
partially closed position.
•
This value is typically set to a value slightly lower than the home detection torque.
•
If the socket is bouncing back to a partially closed position after reaching the home stop, this value is too low.
•
Attention: Setting this value too high can cause the socket to snap back to the home stop too quickly and potentially
damage the tool.
•
Units: lbf-in (approximation)
•
TID memory location: 54

Set the Hold at Home Torque = 0

•
Free run the tool and watch the homing routine while making the adjustments below.
•
Gradually increase the value for the Home Detection Torque until the tool reliably returns to the home position.
•
Once a good value for the Home Detection Torque is found, if the tool is bouncing back to a partially closed position
after hitting the home stop.
•
Gradually increase the value for the Hold at Home Torque until bounce back is eliminated.

Controller parameters for tube-nut operation can be viewed and modified from the Controller->Edit Controller Parameter-

Tube Nut Backoff Speed:
- This is the speed the tool output socket travels when returning to the home position.
- Decreasing this can reduce the impact force when hitting the home stop.
- Attention: Care must be taken, increasing the speed above the default value. Too high of a value can greatly in
crease how hard the output will hit the home stop and potentially damage the tool.
- Units: RPM of the tool output socket in the homing direction
- Default value: 100 RPM.
- Range: 10 to 500 RPM
