Main Features and Advantages
High Power Density in a Compact Frame: The 2198-S086-ERS3 delivers 43 A rms continuous output and 29.7 kW nominal power from an 85 mm wide module, enabling machine builders to achieve high axis power without proportionally expanding panel footprint. In multi-axis systems where several inverters share a common DC bus, this density compounds: a row of 2198-S086-ERS3 modules and companion drives can fit into a fraction of the cabinet space required by earlier generations of discrete drive systems. The 4 kHz PWM frequency and 400 Hz velocity loop bandwidth support responsive motion control for demanding load profiles, including high-acceleration positioning and rapid torque reversals .
EtherNet/IP Integration with the Logix Platform: The 2198-S086-ERS3 operates natively on EtherNet/IP, eliminating the need for a separate motion control network such as SERCOS or analog command interfaces. When paired with a Logix controller, the drive becomes an integrated axis within Studio 5000, sharing tag structures, safety configuration, and diagnostic data with the rest of the machine control system. This unified architecture reduces engineering effort during commissioning and simplifies troubleshooting, because drive faults, position feedback, and tuning parameters are accessible through the same software environment used for the entire machine. The 2198-S086-ERS3 also supports integrated safety functions over the same network connection, including Safe Torque Off and safe speed monitoring, without requiring additional hardwired safety circuits.
Common-Bus Architecture for Energy Efficiency: As a single-axis inverter designed for DC bus sharing, the 2198-S086-ERS3 can absorb regenerative energy from decelerating loads and make it available to other axes on the same bus. In applications with vertical axes, high-inertia loads, or frequent start-stop cycles, this energy-sharing capability reduces the power drawn from the AC line and can lower the overall electrical demand of the machine. The module’s internal capacitance of 560 µF contributes to bus stability during transient load changes, helping to maintain consistent DC link voltage across the drive group .
Safety Integration Without Additional Hardware: The 2198- includes TÜV-certified safety functions rated to PL e, Cat. 3, and SIL 3, enabling machine designs that meet stringent safety standards while reducing component count in the safety circuit . Safe Torque Off can be triggered over EtherNet/IP, and the drive supports timed SS (safe stop) functions that are implemented within the drive itself. For machine builders serving European or North American markets with demanding functional safety requirements, the 2198- provides a certified safety foundation that integrates directly into the Logix safety architecture.
