Sensorless Open-Loop Control Algorithm: With KB’s proprietary sensorless, open-loop control algorithm specifically designed for both induction and BPM motors, these drives do not require encoders but still provide exceptional torque vs. speed characteristics.
Isolated User Interface: The isolated user interface (for analog signal input, Forward-Stop-Reverse, Run/Fault Relay contacts) and circuitry for RS485 ModbusRTU Communication Protocol eliminate the need to purchase andinstall separate interface modules. These drives combine the digitaltechnology of the microprocessor with an easy-to-use isolated analog input user interface.
Electronic Inrush Current Limit (EICL™) Protection: Eliminates harmful inrush AC line current during power up.
Ride-Through: Provides smooth recovery to the previous set speed during a momentary power loss.
Regeneration Protection: Eliminates tripping due to high bus voltage caused by rapid deceleration of high inertial loads.
Undervoltage and Overvoltage Protection: Shuts down the drive if the AC line input voltage goes above or belowthe operating range.
Short Circuit Protection: Shuts down the drive if a short circuit occurs at the motor(phase-to-phase).
Trimpot Adjustments: Min. Speed, Max. Speed, Accel, Decel, Current Limit, Slip Comp.
