Without Filter
Below is a diagram of V
PK
and dv/dt as a function of cable length when
no dv/dt filter is used.
With dv/dt Filter
Below is a diagram of V
PK
and dv/dt as a function of cable length with
dv/dt filter at the output of the ACx 600.
Power Factor
Correction Capacitors
Power factor correction capacitors and surge absorbers must not be
connected between the drive and the motor. These devices are not
designed to be used with AC drives, 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.
