2198-H040-ERS — Kinetix 5500 Single-Axis Inverter Module, 40A, with Safe Speed Monitor

The 2198-H040-ERS is a single-axis inverter module for the Kinetix 5500 servo drive system, rated at 40A continuous output current. It draws DC bus power from a shared converter on the same bus bar rather than rectifying its own AC supply, and drives one servo motor axis through CIP Motion over EtherNet/IP. The ERS designation adds integrated Safe Speed Monitor functionality, providing a hardware-verified speed-limit safety signal independent of the drive's standard motion control loop.

High-Power Single-Axis on a Shared Bus

At 40A, this inverter module sits at the higher end of the Kinetix 5500 single-axis range — large servo motors on demanding axes such as press feeds, heavy gantry drives, or high-torque rotary tables. It's a pure inverter; it has no rectifier of its own and depends entirely on a shared bus fed by a separate 2198-series converter module. This division of labor is the core of the Kinetix 5500 architecture: one converter handles AC-to-DC conversion for the whole group, while individual inverter modules like this one each drive their own axis from the common bus.

The practical consequence is that this module's current rating must be checked against the bus converter's total capacity alongside whatever other axes share the same bus. A 40A inverter axis consumes a meaningful share of most converters' rated input current — verify the complete axis group's RMS current demand against the converter's continuous rating during system sizing, not just this single axis in isolation.

Thermal and Mounting Considerations

At 40A, this module dissipates substantial heat under continuous load — verify panel ventilation or air conditioning is adequate for the combined heat load of this module plus its shared converter and any adjacent axes.
Mount according to the Kinetix 5500 system's bus bar sequencing rules — physical position on the bus relative to the converter affects current sharing and is specified in the system wiring documentation.
Allow clearance for the module's cooling airflow path; recirculating exhaust heat from adjacent modules into this unit's intake accelerates thermal aging and increases fault risk under sustained high load.

FAQ

Q: Can this inverter module operate without a separate converter module?

No. This is a bus-fed inverter only — it has no rectifier stage of its own. A 2198-series converter module supplying the shared DC bus is mandatory for operation.

Q: How many 2198-H040-ERS modules can share one converter's bus?

This depends on the converter's total current rating and the combined RMS current demand of all axes on the bus, not a fixed module count. Use the platform's motion sizing software to verify the complete axis group against the converter's rated capacity.

Q: Does the Safe Speed Monitor function require a safety PLC?

No. The ERS safety inputs and outputs are hardwired and can be driven by a standard safety relay. A safety PLC is not required for the Safe Speed Monitor function itself, though one may be used if the broader machine safety architecture calls for it.

Q: What feedback types does this module support?

Feedback support depends on the connected motor and its feedback cable — Kinetix-compatible motors typically use encoder, Hiperface, or EnDat feedback types matched through dedicated cable assemblies. Verify the motor's feedback type against the inverter's supported configuration before commissioning.
