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.
