The function code is used to
compensate the phase angle of
phase lock. A positive value
indicates that the phase-locked
angle is shifted right by the angle set
compensation angle
by the function code, while a
negative value indicates the
phase-locked angle is shifted left.
(Valid only for the six-pulse rectifier)
Bus voltage judgment hysteresis
upper limit V_ZH = Input voltage
(P08.06)*1.414 + P03.37;
When the actual bus voltage is
greater than V_ZH, the IGBT
feedback enabling angle starts to
increase slowly until it reaches 120
hysterisis degrees.
When the actual bus voltage is less
than V_ZL (see P28.05), the IGBT
feedback enabling angle starts to
decrease slowly until it reaches the
lower limit (see P03.38).
(Valid only for the six-pulse rectifier)
IGBT feedback During six-pulse rectifier mode, the
enabling angle feedback angle can be set through
