The next display is “P TARGET - ”, with a number from 0 through 255. This is the force
reading to which the IMPAX unit will try to calibrate its internal peak detection circuitry during
the automatic adjustment cycle. Enter a three-digit number from 0 to 255, then press Enter/Yes.
PTG/IMPAX recommends that this value be set to 96.
This display will now show “I TARGET - “ with a number from 0 through 255. This is similar
to the function above, except that it deals with the calibrated value for the integrated reading.
The recommended setting for this target is 128. Enter a three-digit number from 0 to 255, then
press Enter/Yes.
Next, the position sensor must be defined. The display will say “POSITION SENSE”; press
Enter/Yes.
It will then say “PROX SW. LINE --1", asking which proximity sensor is to be assigned to this
channel. There may be as many as 2 proximity sensors installed; press the number of the sensor
you wish to select and the press Enter/Yes.
The next display will either be “READ WHILE ON” or “READ WHILE OFF”; this determines
whether the force sensor is ‘looked at’ while the chosen proximity sensor is on or off its metal
cam or flag. Press Next/No if you wish to change the selection, then press Enter/Yes. If you
would like more information on this topic, please refer to the Timing Section of the IMPAX
Installation Guide.
The display will now show “BKST H LIM ON” or “BKST H LIM OFF”. BKST stands for
Backstroke, the return stroke of the moveable die on a flat-die threadroller. BKST H LIM, when
enabled, helps the IMPAX unit interact with a threadroller by allowing the IMPAX to detect a
part stuck to the die during the backstroke. If not detected by IMPAX, such a condition could
damage the tooling. Press Next/No to select between the two choices, then press Enter/Yes to
lock it in. If you select “BKST H LIM OFF”, the next three paragraphs are not applicable.
If you selected “BKST H LIM ON”, the next display will be “BKST HEAD RM -16”.
Backstroke Headroom is the value between the force seen during the backstroke and the HI
LIMIT for a backstroke error. Example: if the backstroke generates a force of * 002 *, and the
BKST HEAD RM IS 16, any backstroke force of * 018 * or above will generate a backstroke
error. Generally BKST HEAD RM should be left at 16 unless there is a problem with erroneous
backstroke errors.
The next display will be “BKST EXC ON” or “BKST EXC OFF”. This option will allow a
preset number of high force errors to occur without stopping the machine. Press Next/No to
select one choice or the other, then press Enter/Yes. Generally, this should be turned off.
The display will either show “NOFEED LIM OFF”, “NOFEED LIM CUMU”, or “NOFEED
LIM CONS”. NOFEEDS are cycles of the machine where no material is fed to the machine for
processing. Usually NOFEEDS are used with piece-fed machines like threadrollers, but under
