# Step Configuration Stages

The controller tightening programs need parameters to be set in order to execute the programs. Selecting a Strategy and either the Target torque or Target angle are mandatory. Other settings are optional. It is also possible to monitor the tightening as it progresses by adding limits within which the torque or angle rotation must remain.

The tightening procedure is divided into four stages: Start, Rundown, Tightening and Stop.

Typical tightening curve

The figure is typical of how tightenings are described. The curves represent how speed, torque and angle vary over time. All tightening strategies are represented in this way. Parameters, monitors and limits are also shown in detailed figures.

A task is defined from the time a trigger is pressed until the tightening target is reached, or an error occurs.

A combination of a tightening strategy together with specific parameter settings forms a tightening program.

The user can create many different tightening programs, and one of them is selected at runtime.
