• LED Status Indicators – The LEDs provide indication of the drive’s status and operating mode

(Hz, PGM, LCL/REM, STOP, FWD, REV, OL, JOG/REM).

• Multi-Function Output Relay Contacts – Can be used to tur

n on or of

f equipment or to signal

a warning if the drive is put into various modes of operation. (The optional IODA Input/Output

Multi-Function Board contains 9 digital and analog inputs, 4 digital and analog outputs, and 2

additional relay outputs.)

• Motor Curr

ent Selection – P

rogrammable motor current allows the drive to be used on a wide

range of motor horsepower.

• Compatible with GFCIs. See Function No. 0.04, on page 32.

PERFORMANCE FEATURES

•

Power Start™ – Provides more than 200% starting torque which ensures startup of high fric-

tional loads.

• Programmable Flux Vector Compensation with Static Auto-Tune and Boost – Provides

excellent load r

egulation and dynamic r

esponse over a wide speed range.

• Speed Range – 60:1

PROTECTION FEA

TURES

• Motor Overload (I

t) with RMS Current Limit – Provides motor overload protection, which

prevents motor bur

nout and eliminates nuisance trips.*

• Electronic Inrush Current Limit (EICL™) – Eliminates harmful inrush AC line current during

startup.

• Short Circuit – Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).

• AC Line Phase Loss Detection (Models KBDA-29**, 45, 48 only.)

• Decel Extend – Eliminates tripping due to bus overvoltage caused by rapid deceleration of

high inertial loads.

• Undervoltage and Overvoltage – Shuts down the drive if the AC line input voltage goes below

or above the operating range.

• MOV Input Transient Suppression.

•

Micr

ocontroller Self Monitoring and Auto-Reboot.

*UL approved as an electronic overload protector for motors.

**When used on 3-phase AC line input set for 7.0 Amps or higher (3 HP (2.25 kW)).
