Acceleration
This setting controls how quickly the tool comes to programmed RPM. The
value is stated in thousand(k) revolutions per minute (RPM) per second(s).
Default setting is 10 which means that at the start of the rundown or
stage, the tool will reach 10,000 RPMs in a one second period of time.
Given the speed ratings of the tools in the AcraDyne range, this means
that the programmed RPM will instantly be running at the throttle press,
or start, of the stage.
To increase the time in which the tool comes up to speed (aka Soft
Starting) the value should be reduced to the level desired.
Controller Firmware will limit the programmed value to effect the tool
down to 10% of its rated speed. This means that a 1,000 RPM tool can
be set to accelerate at 100 RPM/Second. Should an entry be made
that is lower than this value, the Firmware of the controller will run the
step/stage at no less than 100 RPM/Second
For a theoretical example:
A setting of 1 will result in the tool accelerating (reaching the
programmed RPM setting) in a 1,000 RPM step over a time period of
1 second. If the programmed speed was 2,000 RPM it would take
2 seconds to reach that 2,000 RPM setting during that step or stage of
the rundown.
A setting of .5 will result in the tool accelerating (reaching the
programmed RPM setting) in a 500 RPM step over a time period of
1 second. Using the 2,000 RPM example, it would take the tool
4 seconds to reach 2,000 RPM.
Summary: Lower values equal slower ramp up to programmed speed.
Accept Tone
Controls tone made from handle of handheld tools for accepted
fastening cycles.
Angle
Degree fastener rotates from snug, or threshold level, to peak
torque.
Cycle Complete
Torque level that determines completion of a fastening cycle.
High Angle
When peak angle recorded exceeds High Angle, the fastening cycle is
recorded as a reject for High Angle, the High Angle light (flashing yellow)
illuminates, and fastening cycle is given an overall status of NOK.
High Torque
When peak torque recorded exceeds the High Torque, the
fastening cycle is recorded as a reject for High Torque, the High
Torque light (flashing red) illuminates, and fastening cycle is given
an overall status of NOK.
