KEB is expanding its portfolio in the power range up to 5.5 kW/ 30 Nm specifically for dynamic motion tasks in mechanical engineering with the KEB Combivert S6 servo actuators. Real-time connection to the control level is a key feature of these single-axis drives. In the first stage, this was implemented via Ethercat, now the connection to the Siemens or B&R control world follows with Profinet and Powerlink. In "booksize" format, the servo actuators in two mechanical sizes with widths of 50 and 90 mm cover device outputs from 0.75 to 5.5 kW or from 3 to 12 A continuous current at 250 % overload and "servo-optimized" 8 kHz clock frequency for 3-phase connection voltages from 200 to 480 V(AC) 50/60 Hz. An integrated spark interference filter for environments C1 and C2 in accordance with EN61800-3 makes both very low leakage currents (<5 mA) and large motor cables (up to 50 m) possible. Bearing feedback directly from the motor or from the application is recorded and processed via two universal multi-encoder interfaces. In addition to the resolver, incremental TTL and HTL, SIN/COS, SSI, Hiperface, Endat and BISS encoders are supported as standard. For signal processing, digital signals can be connected to eight inputs and two outputs plus one relay and analog signals to two inputs and one output. Functional safety is implemented as standard with the STO safety function in accordance with EN ISO 13849-1, PL e / corresponding to SIL 3 - EN 62061.
