Notes: 1. UL approved as an electronic overload protector for motors. 2. Requires optional software. 3. Signal Isolator and Run/Fault Relay is standard on Models KBVF-45, 48 and optional on all other models. 4. Models KBVF-21D, 22D contain ICL in

lieu of EICL™.

5. Only Models KBVF-21D, 22D, 13, 23, 23D, 14, 24, 24D, 26D contain Motor Filter. 6. In 50 Hz Mode, the DEC/B Trimpot automatically becomes Adjustable Boost.

DESCRIPTION

The KBVF Adjustable Frequency Drives provide variable speed control

for standard 208-230 and 400/460 Volt 50 & 60 Hz 3-phase & PSC AC

induction motors from subfractional thru 5 HP. 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 accel-

eration and deceleration are provided, making the drive suitable for soft-

start applications.

Due to its user-friendly design, the KBVF is easy to install and oper-

ate. 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. For more advanced programming, PC based Drive-Link™

software is available.

Main features include adjustable RMS Current Limit and I

t Motor

Overload Protection.

In 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.

The drive is suitable for

machine or variable torque (HVAC) applications. With optional software, the

drive can be programmed for DC Injection Braking.

For AC line and motor wiring, Models KBVF-21D, 22D, 13, 23, 23D,

14, 24, 24D, 26D contain quick-connect terminals. Models KBVF-27, 29,

45, 48 contain a Barrier Terminal Block. Other features include: adjustable

trimpots (CL, MAX, MIN, DEC/B

ACC, COMP), customer selectable

jumpers (Line Voltage (dual voltage models only), Automatic-Manual

Start/Reset, Motor Fr

equency

, Fr

equency Multiplier

, Forwar

d/Reverse).

Diagnostic LEDs are provided for power (PWR) and drive status (ST).

A Signal Isolator and Run/Fault Relay Output Contacts are provided

on Models KBVF-45, 48 and are optional on all other models. Other option-

al accessories include: Class “A” and “B” AC Line Filters, Dynamic Brake

Module, Multi-Speed Board, Programming Kit, and Modbus

Communication Module. A connector is pr

ovided for easy installation of

accessories. A 5 k

Ω

Main Speed Potentiometer is also included.

DATA SHEET D-800B OPTIONAL ACCESSORIES & FEATURES • SIVFR Signal Isolator and Run/Fault Relay (Part No. 9597) — Provides isolation between a non-isolated signal voltage source and the drive. Run/Fault Relay Output Contacts are also 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 a fault has occurred. Mounts on the side of the KBVF heat sink. Note: Models KBVF-45, 48 contain built-in Signal Isolator and Run/Fault Relay Output Contacts.

Eliminate Harmful Inrush Current Most KBVF drives contain an Electronic Inrush Current Limit (EICL™) circuit.* The EICL™ prevents high AC inrush current each time power is applied to the drive. The EICL™ feature also allows the drive to be rapidly switched “on” and “off” with the AC line. It could be suggested to leave the drive on continuously to avoid the restart problem.
