3.2.76 Angle integrator (PHINT1, PHINT2, PHINT3)

3−246

EDSVS9332K−EXT EN 4.0

3.2.76.3 Input value with sign reversal (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.

– Sets the output PHINT3−STATUS = LOW.

PHINT3-OUT

Change of sign at the input

Fig. 3−201 Function of PHINT3 with sign reversal of the input value when C1150 = 2

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 (+) C1151,

– the value of C1151 is subtracted from the counter content

– PHINT3−STATUS switches to 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

– PHINT3−STATUS switches to HIGH for 1 ms.
