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

Fig. 3−143 Function of PHINT3 with sign reversal of the input value at 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 counter content exceeds the value of (+) C1151
– the value of C1151 is subtracted from the counter content,
– switches PHINT3−STATUS = HIGH for 1 ms.
l 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.
