5.2 PERFORMANCE FEATURES
● High Performance Sensorless Flux Vector Control with Static Auto Tuning: Provides
excellent speed regulation with high torque loads throughout the entire speed range. Auto
energy savings at light loads. Smooth motor torque.
● Library of Advanced Algorithms: Custom programming and PLC functions for OEM
applications.
● Power Start™: Provides more than 200% starting torque, which ensures startup of high
frictional loads.
● Speed Range: Full torque control over a 50:1 speed range.
● Built-In PID with Sleep/Wake and Inverse Functions: Control loop for constant process
control of flow, pressure, level, and temperature. Requires optional IODF Input/Output Multi-
Function Expansion Module.
● Serial Communication: Setup and control via RJ45 Modbus RTU port provides a low-cost
networking solution. DIDF required.
● GFCI Operation: Tripless operation with GFCIs. (May cause increased audible motor noise.)
5.3 PROTECTION FEATURES
● Motor Overload (I
2 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.
● 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-to-phase).
● AC Line Phase Loss Protection: Shuts down the drive if one of the AC Line input phases is
disconnected. Models KBDF-23P, 24P, 27P, 29, 42, 43, 45, 48 only.
● 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.
