COMBIVERT S6 Servo Drive
Product Details
The COMBIVERT S6 servo drive offers real-time EtherCAT communication. Other ethernet-based communication formats supported are EtherNet/IP, Modbus TCP/IP, ProfiNet IRT, Powerlink, and VARAN.
The S6 is narrow with a compact footprint, allowing the drives to be closely mounted together. Housing 2 (up to 2.2kW) is only 50mm wide while housing 4 (up to 7.5kW) is only 90mm wide.
As standard, the S6 includes SIL3 Safe-Torque-Off (STO) and Safe-Brake-Control (SBC) functionality. Extra safety functionality according to ISO 13849 is available, including SS1, SS2, SOS, SLS, SLP, SLI, SDI, SSM. Failsafe over EtherCAT (FSoE) is also available.
Includes an integrated brake output – rated for 2 Amps @ 24VDC.
The S6 servo drive is extremely flexible when it comes to feedback devices. The interface is dual-channel allowing configuration as input or output. Many formats are supported including Incremental TTL/HTL, Resolver, EnDAT 2.1, EnDAT 2.2, Hiperface, and BiSS.
The S6 EtherCAT Servo Drive uses the CiA 402 motion control profile and has an internal 32-bit positioning module for single-axis motion control applications.
