3.2.53.2 Constant input value (PHINT3)
The FB PHINT3 has three modes which can be set via C1150.
Mode C1150 = 2 is in chapter. 3.2.53.3.
C1150 = 0 C1150 = 1
The input PHINT3−LOAD is state−controlled (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 input value at PHINT3−SET and
immediately starts to integrate
– Sets the output PHINT3−STATUS = LOW

Fig. 3−142 Function of PHINT3 with constant input value at C1150 = 0 and C1150 = 1
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 occurs. The counting is continued with the value −32768,
– PHINT3−STATUS switches to HIGH when the value of (+) C1151 is reached.
l If the count 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 of (−) C1151 is reached.
