INTRODUCTION
The Baldor Series 5 Inverters are variable speed controls housed in a rugged NEMA-4X / IP-65 washdown
and watertight die-cast aluminum enclosure. They are designed to operate 208 – 230 and 400/460 Volt 50
& 60 Hz 3-phase AC induction motors from subfractional thru 5HP. The sine wave coded Pulse Width
M
odulated (PWM) output operates at a carrier frequency of 16 kHz which provides high motor efficiency and
low noise. Adjustable Linear Acceleration and Deceleration are provided, making the drive suitable for soft-
start applications.
Due to its user-friendly design, the drive is easy to install and operate. Tailoring to specific applications is
accomplished with selectable jumpers and trimpots, which eliminate the computer-like programming
required on other drives. However, for most applications no adjustments are necessary.
Main features include adjustable RMS Current Limit and I
2
t Motor Overload Protection.* In addition,
Adjustable Slip Compensation with Static Auto-Tune and Boost provides high torque and excellent load reg-
ulation over a wide speed range. Power Start™ delivers over 200% motor torque to ensure start-up of high
frictional loads. Electronic Inrush Current Limit (EICL™) eliminates harmful AC line inrush current. A Run/Fault
Relay is provided, which can be used to turn on or off equipment or to signal a warning if the drive is put
into the Stop Mode or if a fault has occurred. The drive is suitable for machine or variable torque (HVAC)
applications. Also, a jumper is provided for selection of Regenerative or DC Injection Braking.
Standard front panel features include Diagnostic LEDs for “Power On” and “Drive Status”, an On/Off AC Line
Switch, a Start/Stop Switch, and a Main Speed Potentiometer. Other features include a Barrier Terminal
Block to facilitate wiring of the AC line and motor, adjustable trimpots (MIN, MAX, ACCEL, DECEL, COMP,
CL, JOG, BOOST), customer selectable jumpers (Line Voltage (dual voltage models only), Motor
Horsepower, Automatic Ride-Through / Manual Start, Motor Frequency, Frequency Multiplier,
Fixed/Adjustable Boost, Regenerative / Injection Braking, “Run” or “Fault” Output Relay Operation, NO/NC
Stop Contact, Constant/Variable Torque, I

t Overload Selection).
Optional accessories include: Forward-Stop-Reverse Switch, Signal Isolator, Auto/Manual Switch, and Class
”A” AC Line Filter. A connector is provided for easy installation of accessories. Custom software: all models
can be factory programmed for applications which require special timing, PLC functions, and GFCI operation
– contact your local Baldor District Office.
*UL approved as an electronic overload protector for motors.

T
his product complies with all CE directives pertinent at the time of manufacture. Contact your
l
ocal Baldor District Office for Declaration of Conformity. Installation of a CE approved RFI filter is
r
equired. Additional shielded cable and/or AC line cables may be required along with a signal isolator.
