Scaling of PHINTx−OUT

Mathematic description of PHINTx−OUT:

PHINTx

* OUT[inc] + PHINTx * IN[rpm] @ t[s] @ 65536[incńrev.]

t = integration time

Example:

You want to determine the counter content of the integrator at a certain speed at the input and a
certain integration time.

l

Given values:

– PHINTx−IN = 1000 rpm

– t = 10 s

– Start value of the integrator = 0

l

Solution:

– Conversion of PHINTx−IN:

1000 rpm

+ 1000 rev.

60 s

– Calculation of PHINTx−OUT:

PHINTx

* OUT + 1000 rev.

60 s

@ 10 s @ 65536 inc

rev.
