3.2.53.4 Scaling of PHINTx−OUT
Mathematical description of PHINTx−OUT:
PHINTx
* OUT[inc] + PHINTx * IN[rpm] @ t[s] @ 65536[incńrev.]
t Integration time
Example:
You want to determine the count of the integrator with 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.
