Product Description:

The KEB 09.F0.R21-4000 control cabinet delivers versatile AC motor control in a compact, fan-cooled package. As part of the F0 Combivert series, it provides 1.5 kW of V/f power for managing motors up to 4 kW. With a lightweight 2.5 kg design and tiny 175 x 100 x 150 mm footprint, this cabinet fits easily into cramped machinery spaces and control panels. It's an ideal retrofit solution for upgrading fixed-speed drives without replacing existing infrastructure.

This intelligent cabinet expertly varies output frequency from 0-400 Hz to control the speed and torque of 3-phase induction motors. V/f operation maintains the optimal volts-to-hertz ratio at all frequencies for maximum torque per amp. Unlike rheostats and wound-rotor techniques, inverter control achieves huge energy savings while enhancing precision and response. Running at a standard 400V AC supply voltage, the 09.F0.R21-4000 seamlessly replaces old lower-performance motor starters and drives. It can boost production on conveyors, pumps, mixers, and other machinery plagued by abrupt starts and poor speed regulation. Minimize maintenance with smooth acceleration and deceleration that reduces mechanical stress.

Built-in sensorless vector control further refines speed regulation and torque delivery compared to basic V/f drives. By continually optimizing current and slip compensation, the cabinet achieves tighter speed control for sophisticated applications. Quicker response times lead to enhanced productivity and throughput. This smart cabinet includes key safety features such as overload protection, short circuit protection, and an emergency stop button. The emergency stop immediately cuts power during a crisis to prevent equipment damage or injury. It meets strict SIL 3 and Ple standards for industrial safety systems. Installation and configuration are straightforward with default parameter settings for quick out-of-the-box operation. Simply mount the compact cabinet, connect power and motors, and watch your processes improve.
