Product Description:
The KEB manufactured the 21.H6.ACU-11B0 which is a multi-axis drive module for flexible automation systems. It is part of the H6 Combivert series which offers advanced capabilities in a compact package. The drive ensures stable operation, high efficiency and real-time communication.
The KEB 21.H6.ACU-11B0 features a modular, space-saving design that reduces control cabinet size. It incorporates real-time EtherCAT connection to provide quick and efficient data sharing. This drive system is compatible with both synchronous and asynchronous motors. It can operate with or without an encoder. A central cooling solution maximizes heat dissipation extending system life The drive includes integrated safety functions such as Safe Torque Off (STO) and Safe Brake Control (SBC). Additional alternatives for IEC 61508 SIL3 compliance include Safe Limited Speed (SLS) and Safe Direction (SDI). This assures that the system passes rigorous safety regulations in industrial settings. The system switches at 4 kHz and has a power loss of 99W at the heat sink and 39W inside the module. This guarantees consistent performance in challenging conditions. The drive is rated at 400V and 16.5A with a maximum current of 33A and a power output of 7.5 kW.
The 21.H6.ACU-11B0 is excellent for applications demanding high efficiency, space-saving design and built-in safety features. The drive also has a dual encoder interface that can be used with Sin/Cos, EnDat or BiSS encoders. It can work at temperatures ranging from -10 degrees C to 45 degrees C and humidity levels ranging from 5% to 85% (non-condensing). The module's IP20 protection level ensures dependable performance in industrial environment. Its modular design and real-time communication make it an adaptable solution for complex automation jobs.
