2198-H003-ERS2 — Frame 1 Servo Drive, Integrated Safety Over EtherNet/IP, 1.4A Continuous

The 2198-H003-ERS2 is the smallest frame size servo drive in its family, delivering 1.4A continuous and 2.5A peak output current from a wide input range covering 195–264V single-phase, 195–264V three-phase, or 324–528V three-phase. The ERS2 designation means Safe Torque Off is delivered as an integrated safety command over the EtherNet/IP network rather than through dedicated hardwired safety terminals — the safety controller issues the STO command over the same Ethernet connection used for motion data.

Safety Over the Network at the Smallest Frame Size

At Frame 1, this drive sits at the very bottom of its family's power range — small motion axes, light indexing tasks, and applications where the motor itself draws well under an amp continuous. Pairing that small footprint with network-based safety rather than hardwired STO terminals is a deliberate architectural choice for multi-axis systems: instead of running a separate discrete safety wire to every small axis on the machine, the safety command travels over the same Ethernet cable already carrying motion data, reducing wiring complexity proportionally more as axis count increases.

This drive accepts three distinct input voltage configurations on the same physical unit — single-phase or three-phase at the 240V class, or three-phase at the 480V class — which simplifies sourcing for facilities running mixed voltage supplies across different machine zones, since one catalog number covers all three scenarios rather than requiring separate stock for each.

FAQ

Q: Can this drive use hardwired STO instead of the network-based safety function?

No. The ERS2 designation is specifically the integrated-safety variant — it relies on the EtherNet/IP network connection for the STO command rather than discrete hardwired terminals. For hardwired STO at this frame size, the corresponding ERS (non-2) variant is the appropriate choice instead.

Q: Does the network-based safety function require a specific type of safety controller?

Yes. A safety-rated controller capable of issuing certified safety commands over EtherNet/IP is required — a standard (non-safety) controller cannot provide the certified STO function this drive's ERS2 architecture depends on.

Q: Can this drive run from single-phase power at the 480V class?

No. Single-phase operation is supported only at the 195–264V input range. The 324–528V range on this drive is three-phase input only.

Q: Is a feedback converter kit needed for all compatible motors?

It depends on the motor's native feedback protocol. Motors using a Hiperface-to-DSL conversion path require the appropriate converter kit; motors with native DSL feedback connect directly without that additional component.
