l
The FB integrates speed or velocity values at PHINTx-IN to a phase (distance).
l
PHINTx-OUT outputs the count of the bipolar integrator.
– A positive value at PHINTx-IN increments the integrator (count is increased).
– A negative value at PHINTx-IN decrements the integrator (count is reduced).
l
If the count exceeds the value of +32767 encoder revolutions ( +2147483647 inc)
– an overflow results. The counting is continued at the value -32768.
