5 INTRODUCTION
Thank you for purchasing the KBDF Digital AC Drive. KB Electronics, Inc. is committed to
providing total customer satisfaction by providing quality products that are easy to install and
operate.
The KBDF Series of Digital AC Drives are housed in IP-20 enclosures. They are designed to
operate 1/8 thru 5 HP 208 – 230 and 400/460 Volt 50 & 60 Hz 3-phase AC and 1-phase PSC
induction motors.
1 Flux Vector Control provides high torque, low noise, and excellent load
regulation over a wide speed range. Adjustable Linear Acceleration and Deceleration make the
drive suitable for soft-start applications.
Due to its user-friendly design and simple to use and understand instruction manual, the KBDF
is easy to install and operate. Setting the drive to specific applications is accomplished using the
Multi-Function Keypad, which provides easy operation and programming of the drive. To
facilitate programming, all similar functions are presented in common groups. For more
advanced programming, PC based Drive-Link™ software is available.
The 4-Digit Display provides readout of drive operating parameters and programming functions
and displays Output Frequency, Motor RPM, Output Current, Output Voltage, Bus Voltage,
Function Codes and Values, Fault Codes, and Custom Units.
The 8 LEDs provide indication of the drive’s status and operating mode. When used with
process control, the Local/Remote Key can be used to switch from process control to manual
control if a process fault occurs.
The on-board memory can store up to 4 programs and the optional Memory Module can store
an additional 4 programs for cloning and archiving.
Main features include adjustable RMS Current Limit and I
2 t Motor Overload Protection. 2 Power
Start™ delivers over 200% motor torque to ensure startup of high frictional loads and
programmable Injection Braking provides rapid motor stop. Electronic Inrush Current Limit
(EICL™) eliminates harmful AC Line inrush current, allowing the drive to be AC Line switched. A
Multi-Function Output Relay is provided, which can be used to turn on or off equipment or to
signal a warning if the drive is put into various modes of operation. The drive also contains AC
Line Phase Loss Protection.
3 The drive is suitable for machine or variable torque (HVAC)
applications.
For Remote Operation, a removable cover allows access to Multi-Function Input Terminals,
Analog Inputs/Outputs, and Multi-Function Output Relay Contacts. The Potentiometer can be
used to adjust motor speed in lieu of the built-in keypad.
Optional accessories include IODF Input/Output Multi-Function Expansion Module, DIDF
RS-232 and RS-485 Modbus RTU Communication Module, Plug-In Memory Module and PC
Windows® based programming software.
Notes: 1. PSC motor operation requires OEM software – contact our SalesDepartment. 2. UL
approved as an electronic overload protector for motors. 3. Models KBDF-23P, 24P, 27P, 29,
42, 43, 45, 48 contain AC line Phase Loss Protection.
