Frequently Asked Questions
What is the Allen-Bradley 2198-D032-ERS3?
It is a Rockwell Automation Kinetix 5700 dual-axis servo inverter with two motor-control channels, 13 A RMS continuous output current per axis, EtherNet/IP motion communication and ERS3 functional safety capabilities.
How many servo motors can it control?
The module provides two servo axes. Each axis must be configured with a compatible motor, feedback interface and correctly sized electrical and mechanical load.
What is the continuous output current per axis?
Each axis is rated at 13.0 A RMS or 18.3 A zero-to-peak. These are two representations of the same continuous output-current rating.
What is the peak output current?
Each axis supports 32.5 A RMS peak output current, equivalent to 45.9 A zero-to-peak. Peak-current operation is subject to duration and thermal limits specified by Rockwell Automation.
What output power does the module provide?
The continuous output rating is 4.5 kW per axis with a 240 V-class system or 8.9 kW per axis with a 480 V-class system. The total available system power must be checked against the selected DC-bus supply and all connected axes.
Does the 2198-D032-ERS3 connect directly to a 480 VAC supply?
No. It is a DC-bus-fed inverter module. It requires a compatible Kinetix 5700 DC-bus power supply. The 240 V and 480 V classifications refer to the supply-system power ratings rather than a direct three-phase AC input on the inverter itself.
What is the DC-bus input voltage range?
The specified DC input voltage range is 276 to 747 VDC. The DC-bus supply, wiring and system protection must be selected according to the applicable Kinetix 5700 installation documentation.
Does the module support EtherNet/IP?
Yes. It provides dual Ethernet ports for Integrated Motion on EtherNet/IP and supports compatible Logix-based motion control systems.
Does the ERS3 version support Safe Torque Off?
Yes. ERS3 modules support hardwired and integrated Safe Torque Off modes. The selected safety configuration must be designed and validated with compatible safety equipment and the appropriate drive firmware.
Does the 2198-D032-ERS3 support Timed Safe Stop 1?
Series B and later ERS3 modules support Timed Safe Stop 1 under the required firmware and controller conditions. The function should not be assumed available on every older hardware series.
What is the difference between 2198-D032-ERS3 and 2198-D032-ERS4?
Both are Kinetix 5700 dual-axis inverters in the same output-power class. ERS4 adds advanced safety and monitoring functionality, including monitored SS1 and additional supported safety functions. Check controller, firmware and safety-system compatibility before substitution.
Can this module operate without a separate Kinetix 5700 DC-bus supply?
No. Rockwell Automation specifies that a valid Kinetix 5700 servo system requires an appropriate DC-bus power supply module as well as the axis module. Power sizing must include the combined requirements of the installed drives.
Which software is used to configure the module?
The drive is configured using a compatible version of Studio 5000 Logix Designer and the appropriate Kinetix 5700 Add-On Profile. Firmware revision and hardware series compatibility should be checked before modifying an existing system.
What are the mounting dimensions?
The module is 55 mm wide, with approximate overall dimensions of 252 mm high and 358 mm deep. Verify the manufacturer dimension drawing, bus connections and cabinet clearances before installation.
Is the 2198-D032-ERS3 discontinued?
Rockwell Automation currently identifies the 2198-D032-ERS3 as an active product. Confirm the current lifecycle designation and the installed hardware series when planning maintenance or procurement.
What should be checked before ordering?
Confirm the exact catalog number 2198-D032-ERS3, two-axis configuration, 13 A RMS continuous rating per axis, 32.5 A RMS peak rating, required DC-bus supply, 240 V or 480 V system power class, ERS3 safety mode, hardware series, firmware revision, compatible servo motors and feedback, Logix controller, EtherNet/IP communication, physical dimensions and existing cabinet wiring.
