Fig. 9-141 Function of PHINTx with constant input value
z
The FB integrates speed or velocity values at PHINTx-IN to a phase (distance).
z 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).
z 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 ≥ +32000 is reached.
PHINTx-FAIL = HIGH.
z 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 ≤ -32000 is reached.
z 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.
