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.

Obstruction Detection Torque - (in*Lb)
- At the start of rundown before the output rotation has passed though the Obstruction Check Zone (where the
output is open at the start of the fasting cycle), the tool will stop and fastening cycle will be aborted if this torque is
exceeded.
- If the tool stops, when the output is open during this first part of the rundown, without any obstruction, the value is
too low.
- Units: lbf-in
- TID memory location: 53

•
Set the value for the obstruction torque just high enough so the tool will reliably overcome gear friction and make it
past the obstruction checking zone.
•
Check the torque of the stop on obstruction feature by measuring the actual “pinch” torque the tube nut produces at
the start of the rundown when the jaws are open (within the obstruction detection angle range). This can be done on a
semi-tightened joint simulator set for a hard joint, while auditing the torque.
•
Note: Gear friction in the tube-nut head can greatly affect the ability to reliably detect an obstruction.

Controller parameters for soft-start operation can be viewed and modified from the Controller->Edit Controller Parameter->Soft
Start in ToolWare.
•
Soft Start Dwell Speed
- The Soft Start Dwell Speed is used during the check for obstructions.
- Decreasing this can reduce the impact force when hitting an obstruction.
- 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 obstruction.
- Units: RPM of the tool output
- Default: 90 RPM
- Range: 1 to 500 RPM

Tube-nut screen.
• Obstruction Check Angle
- Angle of travel from the start of the fasting cycle where if an obstruction is detected inside this zone, the tool will
stop and the fastening cycle will be aborted.
- Units: Degrees of rotation of the output from home to where the output is closed.
- Default value: 70 Degrees
- Range: 0 to 180 Degrees
•
Obstruction Check Speed Limit
- Maximum speed the output will run during the check for obstructions.
- Decreasing this can reduce the impact force when hitting an obstruction.
- 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 obstruction.
