Strategies

Each strategy consists of a complete set of parameters to control and/or audit torque, angle, time, speed, and power. Each strategy may advance to the next, invisible to the operator, or pause the tool briefly to manage direction changes, multiple spindle synchronization, or relaxation and crosstalk effects.

Smart Steps and Advanced features to use with the strategies on our QB controllers

Wobble – creates a Smart Step with an AC/TM strategy that rotates the fastener in the opposite direction as the Audit step is programmed to overcome wobble. The fastener threads align with the locking device threads before standard forward rotation and high speed are applied (prevents cross-threads).

Slow Seek – allows slow rotation of socket to allow the flats on the socket to meet up with / engage the flats on the fastener / nut before full rotation and fastening.  When selected will be after Wobble, if no Wobble will be first, and before Self-Tap.

Self Tap – allows the tool to compensate for high prevailing torque applications before final tightening.  When selected will be after Slow Seek and before final Torque step.

Manual Downshift – Manual = human determines parameters and controller calculates parameters. In either case the end result is the same Reduces the tool speed to a specific value (Downshift Speed) when a specific torque value (Downshift Torque) is reached during the fastening cycle. Speed units are RPM, torque is in torque units.

Adaptive Tightening Control – Enables the Adaptive Tightening Control algorithm to slow the tool’s speed as the torque rises. The default values can be modified for when the algorithm starts (ATC Starting Torque), when it ends (ATC Ending Torque) and the tool speed after the algorithm ends (ATC Ending Speed). The torque units are a percent of Target Torque. The speed values are a percent of Speed.

Adaptive Tightening Control Plus – Enables the Adaptive Tightening Control Plus algorithm to slow the tool’s speed based on a sampled torque rate. The default values can be modified for when the algorithm starts monitoring rate (Threshold Low), when it stops monitoring rate (Threshold High) and the tool speed after the algorithm ends (Minimum Speed). The torque units are a percent of Target Torque. The speed values are a percent of maximum speed of the tool.
