Fig. 7-153 Function of PHINT3 with change of sign when C1150 = 2
l
The FB integrates speed or velocity values at PHINT3-IN to a phase (distance).
l PHINT3-OUT outputs the count of the bipolar integrator.
– A positive value at PHINT3-IN increments the integrator (count is increased).
– A negative value at PHINT3-IN decrements the integrator (count is reduced).
l If the count exceeds the value of (+)C1151
– the value of C1151 is subtracted from the count
– switches PHINT3-STATUS to for the time of 1 ms.
l If the count falls below the value of (-) C1151
– the value of C1151 is added to the count,
– switches PHINT3-STATUS to for the time of 1 ms.

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=10s
– Start value of the integrator = 0
