3.2.76.4 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:
1000rpm +
1000rev.
60s
– Calculation of PHINTx−OUT:
PHINTx * OUT +
1000rev.
