9.2.54.3 Input value with sign reversal (PHINT3)
C1150 = 2
The input PHINT3-LOAD is state-controlled (HIGH level).
z PHINT3-LOAD = HIGH
– The integrator is loaded with the input value at PHINT3-SET.
– Sets the output PHINT3-STATUS = LOW.

z
The FB integrates speed or velocity values at PHINT3-IN to a phase (distance).
z 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).
z If the counter content exceeds the value of (+) C1151
– the value of C1151 is subtracted from the counter content,
– switches PHINT3-STATUS = HIGH for 1 ms.
z If the counter content falls below the value of () C1151
– the value of C1151 is added to the counter content,
– switches PHINT3-STATUS = HIGH for 1 ms.
