l PHINTX -RESET = HIGH
– sets the integrator to 0
– Sets PHINTx-OUT = 0, as long as a HIGH level is applied to PHINTx-IN.
– Sets PHINTx-FAIL = LOW.
7.6.60.2 Constant input value (PHINT3)
The FB PHINT3 has three modes which can be set under C1150.
Mode C1150 = 2 is described in Chapter 7.6.60.3.
C1150 = 0 C1150 = 1
The input PHINT3-LOAD is state-triggered (HIGH level).
l PHINT3-LOAD = HIGH
– The integrator is loaded with the input value at PHINT3-SET.
– Sets the output PHINT3-STATUS = LOW
The input PHINT3-LOAD is edge-triggered (LOW-HIGH edge).
l PHINT3-LOAD = LOW-HIGH edge
– The integrator is loaded with the input value at PHINT3-SET
and starts adding from this point
– Sets the output PHINT3-STATUS = LOW

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 +32767 encoder revolutions ( +2147483647 inc)
– an overflow results. The counting is continued at the value -32768,
– PHINT3-STATUS switches to HIGH when the value (+)C1151 is reached
l If the count falls below the value of -32768 encoder revolutions ( -2147483648)
– an overflow results. The counting starts at the value +32767,
– PHINT3-STATUS switches to HIGH when the value (-) C1151 is reached
7.6.60.3 Input value with change of the sign (PHINT3)
C1150 = 2
The input PHINT3-LOAD is state-triggered (HIGH level).
l PHINT3-LOAD = HIGH
– The integrator is loaded with the input value at PHINT3-SET.
