Tightening Programs
By selecting the tightening program it is possible to choose the method for applying clamping force (or pre-load) to the joint. Different joints require different strategies for how to apply the desired clamping force and to minimize unwanted in-service effects.Power Focus XC can store up to 1,000 tightening programs.
In the Web HMI, a maximum of 1,000 tightening programs can be created.
In the Mobile HMI, a maximum of 500 tightening programs can be created.
The TurboTight strategy, enables the option to use Manual programming or Quick prog - for more information, see the paragraph TurboTight.
The Quick step, Two step and Three step strategies enable the choice of tightening towards a Target torque or a Target angle value.
The External result strategy, is used when OK tightenings are indicated by an external digital signal - for more information, see the paragraph External result.
All tightening programs require that you at least set the Target torque or Target angle value.
Parameter | Description | Default value |
|---|---|---|
Strategy | Available tightening programs. TurboTight: No additional tightening behavior is used as default. Only target values are used. Quick step: Adds an initial tightening step to reduce pre-load scatter. Two step: Adds a pause between the first and final tightening step to further counteract short-term relaxation effects. Three step: Tightens to a defined First torque value, then loosens the screw and immediately retightens it to Target torque or Target angle. Wrench - production: Tightening strategy to use with an ST Wrench. Wrench - quality: Strategy used for quality test of tightenings with an ST Wrench. Rotate: Rotates the spindle a specified speed and angle. External result: presents a predetermined tightening result instead of measured torque/angle. Multistep: Tightening strategy consisting of multiple configurable steps, with restrictions and monitors. | TurboTight |
Target type | Defines the type of the target value in the final step. Target torque: The tightening aims towards the specified target value when performing the final step. Target angle: The tightening aims towards the specified target value when performing the final step. |
|
Target torque | Defines the target torque of the tightening of the final step. |
|
Target angle | Defines the target angle of the tightening of the final step. |
|
Target speed | Activates setting the tool speed for the final step manually or using the default speed. Auto: Uses a value that is calculated based on the Tool max speed. Manual: Specify the tool speed manually. | Auto |
<Manual> | Tool speed during tightening or during the final step. |
