Frequently Asked Questions
What is the Allen-Bradley 2198-H008-ERS2?
It is a Rockwell Automation Kinetix 5500 Frame 1 servo drive with Integrated Motion on EtherNet/IP, network-based Safe Torque Off functionality and support for compatible AC servo motors.
What input voltage does the 2198-H008-ERS2 support?
It supports 195 to 264 VAC RMS single-phase or three-phase input and 324 to 528 VAC RMS three-phase input. Rated power output depends on the selected voltage and phase configuration.
What is the rated output power?
The manufacturer specifies 0.5 kW at 240 V single-phase, 0.8 kW at 240 V three-phase and 1.6 kW at 480 V three-phase. The 1.6 kW figure applies to the 480 V three-phase configuration.
Is the continuous output current 3.5 A or 2.5 A?
Both values are correct under different measurement conventions. The manufacturer specifies 3.5 A continuous as a zero-to-peak value and 2.5 A continuous as an RMS value.
What is the maximum peak output current?
The rated peak output current is 8.8 A zero-to-peak or 6.25 A RMS under the applicable manufacturer conditions. Peak current must not be treated as the continuous output rating.
What is the difference between 2198-H008-ERS and 2198-H008-ERS2?
Both are Kinetix 5500 drives with the same basic power class. The 2198-H008-ERS uses hardwired Safe Torque Off connections, while the 2198-H008-ERS2 implements integrated Safe Torque Off over EtherNet/IP. Their safety integration requirements differ.
Does this drive support CIP Safety?
Yes. The ERS2 model supports integrated safety over EtherNet/IP, including Safe Torque Off commands through a compatible safety controller. The full safety system must be designed and validated for the required safety performance.
Can the 2198-H008-ERS2 use a hardwired STO connector?
The ERS2 model does not use the hardwired STO connector provided for ERS variants. Its integrated STO functionality is controlled through the appropriate network safety configuration.
Does the servo drive support EtherNet/IP?
Yes. It supports Integrated Motion on EtherNet/IP through its dual-port Ethernet interface. The controller and communication configuration must support the required motion and safety connections.
Does the drive require a separate 24 VDC supply?
Yes. Separate 24 VDC control power is required. Rockwell Automation specifies 0.4 A control current without a motor brake and 2.4 A with the referenced 2 A motor-brake configuration.
Which servo motors are compatible?
The Kinetix 5500 is designed for compatible Kinetix VP servo motors using Hiperface DSL feedback. Certain other Rockwell Automation motor and actuator families can be used with supported conversion accessories. Verify the exact motor catalog number using the system design guide.
Does the 2198-H008-ERS2 support multiple servo axes?
One drive controls one servo axis. Compatible Kinetix 5500 drives can be installed together in multi-axis configurations using supported shared AC/DC bus connections and coordinated Logix motion control.
What are the physical dimensions?
The standard Frame 1 housing is approximately 50 mm wide, 215 mm high and 226 mm deep with the specified feedback connector arrangement. Additional clearance is required for cables and cabinet ventilation.
What is the operating temperature range?
The specified ambient operating range is 0 to +50°C. Rockwell Automation recommends 40 mm clearance above and below the vertically mounted drive for airflow and installation.
Is the 2198-H008-ERS2 discontinued?
Rockwell Automation currently identifies the 2198-H008-ERS2 as an active product in its catalog. Product lifecycle classifications may change, so confirm the latest status when planning a new system or maintenance program.
What should be checked before ordering?
Confirm the exact catalog number 2198-H008-ERS2, Kinetix 5500 Frame 1 configuration, single-phase or three-phase supply, power rating for the intended supply voltage, continuous RMS and peak current requirements, integrated CIP Safety STO architecture, compatible motion controller, motor and Hiperface DSL feedback, 24 VDC control supply, wiring accessories, mounting dimensions and existing system firmware compatibility.
