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 PHINT X −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.
