Thank you for purchasing the KBWK Digital AC Drive. KB Electronics, Inc. is committed to providing total customer satisfaction by providing quality products that are easy to install and operate. The KBWK drive is housed in NEMA 1 / IP 20 enclosure. It is designed to operate subfractional through 1/2 HP 208 – 230 Volt 50 and 60 Hz 3-phase AC and PSC 1 induction motors. Flux Vector Control provides high torque, low noise, and excellent load regulation over a wide speed range. Adjustable linear acceleration and deceleration make the drive suitable for soft-start applications. Due to its...

5.1 STANDARD FEATURES Simplified Programming: Programmable functions are organized into easy-tounderstand intuitive groups (common sense programming (CSP)). Factory programming available. Current and Torque Limit: Current and torque limiting in motoring and braking quadrants. Automatic extending of Accel and Decel eliminates nuisance tripping caused by rapid acceleration and deceleration of high inertial loads. Spin Start operation catches a spinning load and allows a smooth return to the set motor speed. 4-Digit Display and 8 LEDs: Provide readout of programming functions and indication of...

5.4 PROTECTION FEATURES 2 Motor Overload (I t) with RMS Current Limit: Provides motor overload protection which prevents motor burnout and eliminates nuisance trips. UL approved as an electronic overload protector for motors. See Section 6.2 below. Electronic Inrush Current Limit (EICL™): Eliminates harmful inrush AC Line current during startup and allows rapid start with AC Line. Short Circuit: Shuts down the drive if a short circuit occurs at the motor (phase-tophase). Regeneration: Eliminates nuisance tripping due to bus overvoltage caused by rapid deceleration of high inertial loads....
