SKQmaster
SKQmaster (machine inconsistency compensator)
Some machines tend to vary slightly in speed during the run, or may have a trigger pulse taken from
an unstable running side shaft (instability often observed on machines with chain-driven side
shafts).
The RPM fluctuation will cause the force waves forms to bounce sidewards left and right. In order
to overcome this, you would typically open the envelope band to accommodate for that. At the
same time, however, you will loose sensitivity but still experience occasional nuisance shut downs.
The SKQmaster function now stabilizes the force signal by automatically compensating left-right
bouncing of the wave form. This allows you to run the usual tight envelopes or envelope profiles,
and it significantly minimizes nuisance shut-downs.
Without SKQmaster:
- machine speed inconsistencies cause the force curves
to bounce left and right
- envelope limits need to be set wide open to allow the
machine to run. You loose sensitivity.
- still erratic force curves occur causing the machine
to stop without apparent reason
This force curve is outside envelope!
With SKQmaster:
- the signal is automatically stabilized. RPM fluctuation
is compensated.
- envelope now can be set close around the actual
process. You regain the necessary sensitivity.
- nuisance shut-downs are avoided.
