4.3.2 Learn Parameters
Learn Gain
At the start of the learning process, the crimp force monitor
uses the GAIN setting
configured in the Learn Gain parameter.
For certain low force crimping applications where more sensor signal amplification is
required, the GAIN can be increased to achieve more signal amplification to ensure
the force signal is detected by the crimp force monitor.
Learn
Tolerance (%)
During the learn process, signatures are captured and compared prior to the calculation
of the reference or learn curve.
The learn tolerance is the maximum allowable variation between the individual
signatures. If during the learn procedure the signature exceeds the learn tolerance
when compared to the other learn signatures, it will be excluded from the calculation of
the reference target curve.
Min. Samples
Minimum number of signatures required to establish the reference or learn curve.
Each signature must not vary from the other signatures by more than the
Learn Tolerance
.
In Learn mode, the first press cycle determines the gain level, and is in addition to the
minimum number of cycles required to complete the learn process.
Max. Samples
Maximum number of machine cycles permissible to learn a process.
If the crimp force monitor does not learn a process after the maximum press cycle limit is
reached, then the learn process has failed and will be restarted.

Proc Dev
The crimp force monitor utilizes a variety of methods to continually monitor the current
state of the process and adjust the reference force signature accordingly. These
adjustments allow the crimp force monitor to accommodate normal variations such
as terminal stock thickness changes or minor tooling wear.
The adjusted reference curve is compared to the reference curve established by
the learn
Process at the start of production and should it vary by more than the allowable
limit as defined by the Maximum Process Deviation parameter the crimp force
monitor will immediately stop production.
This ensures that the adjusted reference curve remains within an allowable
range from the initial reference curve calculated by the
learn process.
Target Recalc
Rate at which the crimp force monitor performs adjustments to the reference curve,
selectable from 2 to 64 good pieces
