POLE FILTER
(Pole Filter Setting)
This parameter adds a low pass
filter to the line side to help
alleviate nuisance noise issues.
This can be very useful in
situations where multiple drives
are located on the same line.
For one Quattro DC on the line,
2.2kHz setting is recommended.
Setting this parameter between
0.1 and 0.9 kHz, an 800 Hz 2
nd
order lowpass filter, plus a 2
nd
order notch filter is added to the
line side.
Setting this parameter to 1.0
kHz, an 800 Hz 2
nd
order
lowpass filter is added.
Setting this parameter between
1.1 and 3.0, a cascaded 2
nd
order notch filter is added with
the center frequency the setting
of POLE FILTER.
kHz 2.2 0.1 – 3.0
Y N
PRE CHGE THRESH
(Pre-Charge Threshold) This
parameter determines the
allowable variance between
actual and calculated Bus
Voltage during power up.
Failure to meet this threshold
will result in a LS CHARGE
Fault and can be an indication
of a loaded down Bus. Most
applications should use the
default value. Lowering this
value tightens the tolerance and
lead to nuisance faults. Raising
this value can cause loose
tolerance and risk damage to
Pre-Charge Resistors.

FREQUENCY
(Line Side PWM Frequency)
This parameter sets the PWM
or ‘carrier’ frequency of the
converter portion of the drive.
