Table 1: Quick Start Parameters for Vector Plus and Vector VII Applications (cont'd.)
Parameter Name Default Information
DHXFormer Ratio 0.00 Transformer Ratio of the step
up transformer used to drive the
medium voltage motor from the
low voltage drive. Calculated
by dividing the transformer
tap voltage by the transformer
rated input voltage (usually
480 Vac). For example, if a
480 Vac transformer is tapped for
2400 Vac, set the DHXFormer
Ratio to 2400 Vac/480 Vac = 5.0.
Note that the default setting of
0.00 requires this parameter be
set prior to running the drive.
Min Frequency 30.0 Hz Minimum speed, in Hertz, of
the Vector Plus drive in the
current pumping application.
Min Frequency should be set to
ensure adequate fluid is pumped
past the pump for cooling. For
ESP applications, Min Frequency
settings lower than 30 Hz are not
recommended.
Max Frequency 60.0 Hz
Maximum speed, in Hertz, of
the Vector Plus drive in the
current pumping application.
Max Frequency should be set
to prevent overstressing the
pumping system components.
Accel Seconds 5.0 Seconds Acceleration ramp time, in
seconds, for the Vector Plus drive
from 0 Hz (stopped) to Maximum
Frequency. For ESP applications,
maximum recommended Accel
Seconds is 10.0.
