3.2.76 Angle integrator (PHINT1, PHINT2, PHINT3)

3−245

EDSVS9332K−EXT EN 4.0

C1150 = 0 C1150 = 1

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

Fig. 3−200 Function of PHINT3 with constant input value when C1150 = 0 and C1150 = 1

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
