• 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 turn on or off 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 Current Selection – Programmable 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.
3.2 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 regulation and dynamic response over a wide speed range.
• Speed Range – 60:1
3.3 PROTECTION FEATURES
• Motor Overload (I 2 t) with RMS Current Limit – Provides motor overload protection, which
prevents motor burnout 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.
• Microcontroller 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)).
