Determining the appropriate program settings
The K-DUCER is a highly accurate system, but it is critically important to select the
appropriate settings to ensure that the desired torque is correctly applied, and that the
screwdriver motor works effectively and efficiently.
Determining the appropriate program settings for your application requires careful
consideration and is ideally done by a trained engineer with knowledge of the torque
specifications and of the mechanical characteristics of the assembly joint.
Please take advantage of the free support provided by your Kolver representative
throughout this process.
What follows are some general guidelines, but they are not meant to substitute a careful
examination of the application. Each application is unique and may require significant
deviations from these guidelines.
These guidelines are always superseded by the specifications of the assembly joint and by
all safety requirements of the operator and work environment.
Kolver is not responsible for damages or injuries resulting from following these guidelines.
Hard/inelastic joints
These joints are best finished at low speed, to improve precision and avoid a high velocity
impact at the end of the tightening.
Choose a low FINAL SPEED such as 100 RPM*, and if desired, use a two-speed approach
by activating the DOWNSHIFT setting using either an angle threshold or a torque
threshold equal to 20-50% of the target torque.
The lower the torque target is relative to the range of the screwdriver, the higher the effect
of motor inertia will be, requiring a lower final speed to avoid overshooting.
Soft/elastic joints
These joints are best executed at high speed, to avoid exposing the motor to a prolonged
time-under-tension and
overheating the tool .
Choose a higher FINAL SPEED for these joints, and if a two speed approach is required,
activate the DOWNSHIFT setting using either an angle threshold or a torque threshold of at
least 80% of the target torque to ensure most of the torque is applied at higher speed.
Very elastic joints, or semi-elastic joints with a high target torque relative to the range of the
screwdriver, may benefit from a higher
FINAL SPEED and from avoiding the use of the
DOWNSHIFT function altogether.
*for KDS-PL15 and smaller high-speed drivers. Use a lower speed for higher torque tools.
