Fig. 3−141 Function of PHINTx with constant input value

l The FB integrates speed or velocity values at PHINTx−IN to a phase (distance).

l PHINTx−OUT outputs the count of the bipolar integrator.

– A positive value at PHINTx−IN increments the integrator (count is increased).

– A negative value at PHINTx−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.

– PHINTx−FAIL switches to HIGH when the value w +32000 is reached.

PHINTx−FAIL = HIGH.

l If the count falls below the value of −32768 encoder revolutions (¢ −2147483648 inc)

– an overflow occurs. The counting starts at the value +32767.

– PHINTx−FAIL switches to HIGH when the value v −32000 is reached.

l PHINTX−RESET = HIGH

– sets the integrator to 0

– sets PHINTx−OUT = 0, as long as a HIGH level is applied to PHINTx−IN.

– sets PHINTx−FAIL = LOW.
