The input PHINT3−LOAD is state−triggered (HIGH level).
·
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).
·
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 angle (distance).
l PHINT3−OUT outputs the counter content of the bipolar integrator.
– A positive value at PHINT3−IN increments the integrator (counter content is increased).
– A negative value at PHINT3−IN decrements the integrator (counter content is reduced).
l If the counter content exceeds the value of +32767 encoder revolutions ( ¢ +2147483647 inc)
– an overflow occurs. The counting is continued with the value −32768,
– PHINT3−STATUS switches to HIGH when the value (+) C1151 is reached
l If the counter content falls below the value of −32768 encoder revolutions
(
¢ −2147483648 inc)
– an overflow occurs. The counting starts at the value +32767,
– PHINT3−STATUS switches to HIGH when the value (−) C1151 is reached
