as a function of cable length when
no du/dt filter is used.
With du/dt Filter
Below is a diagram of

as a function of cable length with
du/dt filter at the output of the ACx 600.
Power Factor
Compensation
Capacitors
Power factor compensation capacitors and surge absorbers must not
be connected to the motor cables. These devices are not designed to
be used with frequency converters, and will degrade motor control
accuracy. They can cause permanent damage to the ACx 600 or
themselves due to the rapid changes in the ACx 600 output voltage.
If there are power factor compensation capacitors in parallel with the
ACx 600 make sure that the capacitors and the ACx 600 are not
charged simultaneously to avoid voltage surges which might damage
the unit.
