3.2.53 Phase integrator (PHINT)

3−153

EDSVS9332S−EXT EN 2.0

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

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.
