7.6.58 Actual phase integrator (PHDIFF)
Purpose
Deliberate addition of a phase signal to the setpoint phase.
A comparison between setpoint and actual phase signals is also possible.

l
The speed signal at PHDIFF1-IN is integrated by the actual phase integrator.
l
The phase signal at PHDIFF1-ADD is integrated to the integrated speed signal.
l
The result of the actual phase integrator is subtracted from the phase signal at PHDIFF1-SET.
C1230/1 = LOW
