2198-D020-ERS3 — 5700 Series Dual-Axis Servo Inverter, 8A RMS per Axis, Hardwired Safety

The 2198-D020-ERS3 is a dual-axis inverter module from the 5700 series, controlling two independent servo axes from a single physical unit with 8A RMS continuous output current per axis (11.3A 0-pk continuous, 20A RMS / 28.2A 0-pk peak). It draws DC bus power from a separate compatible power supply module rather than rectifying its own AC supply, communicates over dual EtherNet/IP ports supporting Device Level Ring or linear topology, and includes hardwired Safe Torque Off.

Two Axes in One Inverter Module

Consolidating two servo axes into a single inverter module is the defining efficiency argument for this product — rather than two separate single-axis inverter modules, each with their own enclosure and mounting footprint, this design fits two complete axes of control into one physical unit on the shared DC bus. For multi-axis machines with several similar-sized axes, this meaningfully reduces panel footprint and the number of individual modules to mount, wire, and maintain compared to an all-single-axis architecture at the same total axis count.

Because this is purely an inverter — no rectifier stage of its own — it depends entirely on a separate, compatible DC-bus power supply module feeding the shared bus. Multiple dual-axis inverters can share one power supply's bus, with the power supply's total current rating needing to cover the combined demand of every axis drawing from it, not just the axes on this specific module.

FAQ

Q: Can this dual-axis inverter operate without a separate power supply module?

No. It has no rectifier stage of its own and depends entirely on a compatible DC-bus power supply module to feed the shared bus — standalone operation isn't possible.

Q: Are the two axes on this module independently controlled, or do they share a single motion profile?

Each axis is independently controlled with its own motion profile and feedback — the two axes simply share the physical inverter housing and the DC bus connection, not the actual motion control.

Q: What topologies do the dual EtherNet/IP ports support?

Device Level Ring and linear topology are both supported, giving the module flexibility to participate in a ring network for fault-tolerant connectivity or a simple daisy-chained linear connection depending on the system's network design.

Q: How many of these dual-axis inverters can share one DC-bus power supply?

This depends on the power supply's total current rating relative to the combined demand of every axis sharing that bus — not a fixed module count. Sizing should be verified using the platform's system design tools against the actual planned axis group.
