1 QUICK-START INSTRUCTIONS
Important –
are to be used as a reference only and are not intended to replace the details provided herein.
You must read the Safety Warning on, pages 8 and 9, before proceeding.
See Figure 1 on page 5. Also see Section 4 – Important Application Information, on pages 20 – 22.
You must read these simplified instructions before proceeding. These instructions
WARNING! Disconnect main power when making connections to the drive.
1.1 AC Line Connection –
shown in Figure 16, on page 31. See Section 9.1, on pages 30 and 31.
Application Note: Do not wire this drive to a GFCI. If operation with a GFCI is required,
contact our Sales Department.
Models KBVF-13, 14 – Rated for 115 Volt AC line input only.
Models KBVF-23, 24 – Rated for 208/230 Volt AC line input only.
Models KBVF-21D, 22D, 23D, 24D, 26D* – Rated for 208/230 Volt AC line input with
Jumper J1 (on upper PC board) set to the “230V” position (factory setting). Rated for 115 Volt
AC line input with Jumper J1 (on upper PC board) set to the “115V” position ).
*On Model KBVF-26D, Jumper J1 is labeled “115VAC” and “230VAC”.
1.2 Ground Connection – Connect the ground wire (earth) to the ground screw, as shown in
Figure 16, on page 31. See Section 9.2, on page 31.
Note: Model KBVF-21D, due to its double insulated design, does not contain a ground screw.
6
Wire the single-phase AC line input to Terminals “L1” and “L2”, as
1.3 AC Line Fusing – It is recommended that a fuse(s) or circuit breaker be installed in the AC
line. Fuse each conductor that is not at ground potential. For the recommended fuse size, see
Table 1, on page 14. Also see Section 10, on page 35.
1.4 Motor Connection – Wire the motor to quick-connect Terminals “U”, “V”, “W”, as shown in
Figure 16, on page 31. (Special reactors may be required for cable lengths over 100 ft. (30 m)
– consult our Sales Department.) See Section 9.3, on page 31.
Note: The drive is programmed to operate 3-phase AC induction motors. For PSC motors,
optional software is required – contact our Sales Department.
1.5 60 Hz and 50 Hz Motor Operation (Jumpers J1 and J2 On the Lower PC Board) – The
drive is factory set for 60 Hz motor operation (Jumper J1 set to the “60Hz” position and
Jumper J2 set to the “X1” position). For 50 Hz motor operation, set Jumper J1 to the “50Hz”
position and be sure Jumper J2 is set to the “X1” position. See Section 6.2.1, on page 26.
1.6 Trimpot Settings – All trimpots have been factory set for most applications, as shown in
Figure 4, on page 20. Some applications require adjustment of the trimpots in order to tailor
the drive for a specific requirement. See Section 13, on pages 38 – 43.
1.7 Main Speed Potentiometer Connection – For unidirectional speed operation, wire the 5 kΩ
potentiometer (supplied) to Terminals “P1” (low), “P2” (wiper), “P3” (high). See Section 9.4, on
pages 31 and 32.
1.8 Voltage Following – An isolated* 0 – 5 Volt DC analog signal input can be used to control
motor speed in lieu of the Main Speed Potentiometer. The drive output will linearly follow the
analog signal input. Connect the signal input positive lead (+) to Terminal “P2” and the negative lead (–) to Terminal “P1”. See Section 9.5, on pages 32 and 33.
*If a non-isolated signal is used, install the SIVFR — Signal Isolator (Part No. 9597). The SIVFR
accepts voltage (0 to ±2.5 thru 0 to ±25 Volts DC) or current (4 – 20 mA DC) signal inputs.
See Section 3.5, on page 13.
7
Note: For signal following operation, the Minimum Speed Trimpot (MIN) must be set fully
counterclockwise.
WARNING! The signal input must be isolated from the AC line. Earth grounding
signal wiring will damage the drive and void the warranty. It is recommended that
the SIVFR — Signal Isolator and Run/Fault Relay (Part No. 9597) be installed when
using signal following.

This product should be installed and serviced by a qualified technician, electrician, or
electrical maintenance person familiar with its operation and the hazards involved.
Proper installation, which includes installation of the Finger-Safe Cover, wiring, mounting in proper
enclosure, fusing or other current protection, and grounding can reduce the chance of electrical
shocks, fires, or explosion in this product or products used with this product, such as electric
motors, switches, coils, solenoids, and/or relays. Eye protection must be worn and insulated
adjustment tools must be used when working with drive under power. This product is constructed
of materials (plastics, metals, carbon, silicon, etc.) which may be a potential hazard. Proper shielding, grounding, and filtering of this product can reduce the emission of radio frequency interference
(RFI) which may adversely affect sensitive electronic equipment. It is the responsibility of the equipment manufacturer and individual installer to supply this Safety Warning to the ultimate end user of
this product. (SW/FSC 5/2005) Be sure to follow all instructions carefully. Fire and/or electrocution
can result due to improper use of this product.
This product complies with all CE directives pertinent at the time of manufacture. Contact
our Sales Department for Declaration of Conformity. Installation of a CE approved RFI filter is
required. See RFI Filters & Chokes Selection Guide D-321 (Part No. A42027) for selection of filters
to meet the Industrial or Residential Standard. Additional shielded cable and/or AC line cables may
be required along with a signal isolator (SIVFR (Part No. 9597)).
3 INTRODUCTION
Thank you for purchasing the KBVF Adjustable Frequency Drive. KB Electronics, Inc. is committed
to providing total customer satisfaction by producing quality products that are easy to install and
operate. The KBVF is manufactured with surface mount components incorporating advanced
circuitry and technology. A Finger-Safe Cover is included for added liability protection.
9
The KBVF Adjustable Frequency Drives provide variable speed control for standard 3-phase and
Permanent Split Capacitor (PSC)
1
AC induction motors from subfractional thru 11⁄2 HP. This manual
covers models with single-phase AC line input only. The sine wave coded Pulse Width Modulated
(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 KBVF AC drive is easy to install and operate. Tailoring to specific
applications is accomplished with selectable jumpers and trimpots, which eliminate the computerlike programming required on other drives. However, for most applications no adjustments are necessary. For more advanced programming, PC based Drive-Link™ software is available.
2
Main features include adjustable RMS Current Limit and I
t Motor Overload Protection.2In addition,
Adjustable Slip Compensation with Static Auto-Tune and Boost provides high torque and excellent
load regulation over a wide speed range. Power Start™ delivers over 200% motor torque to ensure
startup of high frictional loads. Electronic Inrush Current Limit (EICL™) eliminates harmful AC line
inrush current.
3
The drive is suitable for machine or variable torque (HVAC) applications. With option-
al Drive-Link™ software, the drive can be programmed for DC Injection Braking.
For AC line and motor wiring, quick-connect terminals are provided. Other features include:
adjustable trimpots (MIN, MAX, ACC, DEC/B
4
, COMP CL), customer selectable jumpers (AutomaticManual Start, Motor Frequency, Frequency Multiplier, Forward/Reverse, and Line Voltage (dual voltage models only)). Diagnostic LEDs are provided for power (PWR) and drive status (ST). A 5 k
Main Speed Potentiometer is also included.
A Signal Isolator is optional on all models, which can be used for single-ended or bidirectional speed
control and accepts voltage or current signal input. Other optional accessories include: Class “A”
and “B” AC Line Filters, Dynamic Brake Module, Multi-Speed Board, Programming Kit, and Modbus
Communication Module. A connector is provided for easy installation of accessories.
