3.2 PERFORMANCE FEATURES
▪ Power Start™ – Provides more than 200% starting torque which ensures startup of high frictional
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).
▪ 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 (UL File E188974).
3.4 PROTECTION FEATURES
▪ AC LINE INPUT VOLTAGE SELECTION: (115/230 Volts AC) (J1)

Notes: 1. The drive is factory set for 208/230 Volt AC line input (J1 not installed). For 115 volt AC line input, install
Jumper J1 (supplied). See Figure 10, on page 14. 2. Model KBMK-24DF contains a built-in AC line Class A RFI
(EMI) filter which meets the CE Council Directive 89/336/EEC Industrial Requirement.
