9.2.54.2 Constant input value (PHINT3)
The FB PHINT3 has three modes which can be set via C1150.
Mode C1150 = 2 is in chapter. 9.2.54.3.
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

z The FB integrates speed or velocity values at PHINT3-IN to a phase (distance).
z 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).
z 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.
z 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.
