enable addresses problem with very
high DC-link voltage ripple
with 1-phase drives when fully
loaded. Very high ripple in DC
link voltage will transform to
high current and torque ripple,
which can disturb some users.
Voltage limiter function limits
maximum output voltage to
bottom of DC-voltage ripple.
This reduces current and
torque ripple, but decreases
maximum output power since
voltage is limited and more
current is needed.
0 = Disabled
1 = Enabled
NOTE: These parameters are shown, when
P16.2 = 0.
