About the Drive
This chapter describes how to identify the drive using the model number matrix and
shows the major drive components.
The LiquiFlo 1.5 AC drive is a PWM (pulse-width-modulated) liquid-cooled drive that
provides vector and general purpose regulation for a wide range of applications.
2.1 Identifying the Drive by Model Number
Each LiquiFlo 1.5 AC drive can be identified by its model number. See figure 2.1. This
number appears on the shipping label and on the drive’s nameplate. Drive power
ratings are provided in table 2.1.
Figure 2.1 – Identifying the Drive Model Number
LF15 0414 R 4
LF15 = LiquiFlo 1.5
Continuous Ampere Rating
0414 = 414 amps
0500 = 500 amps
0643 = 643 amps
1200 = 1200 amps
Coolant Method
R = refrigerant R134a
W = water-cooled
Voltage
4 = 440 to 480 VAC
