Product Introduction
Kollmorgen S30361-NA SERVOSTAR 303 Servo Amplifier
The Kollmorgen S30361-NA is a SERVOSTAR 303 servo amplifier designed for brushless AC servo motor control. As part of the S300 drive family, it accepts 115–230 VAC input and provides 3 A RMS continuous output current per phase, with a 9 A peak rating for short-duration operation. It is intended for industrial motion systems requiring controlled motor torque and speed.
S30361-NA
For replacement projects, the most important checks are motor compatibility, feedback type, input supply, and drive configuration. The S300 documentation identifies supported feedback options, including SFD3 and HIPERFACE DSL. A replacement should be matched to the existing motor and control architecture rather than selected by current rating alone.
Application Scenarios & Field Pitfalls
The S30361-NA is suited to machinery with brushless servo axes where controlled acceleration, speed regulation, and positioning are required. Because the model is discontinued, maintenance teams should pay particular attention to the condition of stored units and the availability of matching feedback cables and configuration documentation.
Potential application areas
- CNC machinery and automated machine tools using brushless servo axes.
- Packaging and assembly equipment requiring repeatable positioning.
- Material-handling systems with servo-controlled motion.
- Legacy production machinery built around the Kollmorgen S300 drive platform.
Engineer checks before replacement
- Confirm the supply configuration. The S30361 model supports 115–230 VAC single- or three-phase input. Check the actual installation wiring and supply voltage before energizing the replacement.
- Check peak-current duration. The 9 A peak rating is specified for a limited two-second interval. It is not a continuous operating rating.
- Match motor feedback. Verify whether the motor uses SFD3, HIPERFACE DSL, or another supported feedback arrangement. Confirm the correct cable and connector configuration.
- Preserve drive parameters. Record motor data, tuning parameters, command scaling, enable logic, and fault settings before removing the original drive.
- Inspect the condition of surplus stock. Check storage history, corrosion, connector condition, internal contamination, and evidence of previous repairs. A unit described as unused may still require electrical inspection before commissioning.
Related Products
These models belong to the broader Kollmorgen servo-drive family. Their electrical ratings and motor compatibility differ, so they should be treated as comparison references rather than automatic substitutes.
- S30661-NA — Higher-current drive with 6 A continuous and 15 A peak output. Consider only when the motor, supply, and application requirements match.
- S31061-NA — drive rated at 10 A continuous and 20 A peak output. Its higher current capacity does not establish direct interchangeability with the S30361-NA.
- S30101-NA — drive for a different input-voltage class, rated for 208–480 VAC and 1.5 A continuous output. It is not a direct electrical substitute.
- S30301-NA — 3 A continuous drive designed for 208–480 VAC input. Although its continuous current rating matches the , its input-voltage class is different.
- S30601-NA — 6 A continuous drive for 208–480 VAC systems. Check motor sizing and supply requirements before considering it.
- SERVOSTAR 306 — Related drive designation associated with the S30661 model. It provides a higher current rating and may be relevant when reviewing system capacity.
- SERVOSTAR 310 — Higher-capacity drive associated with the S31061 model. It serves applications with greater current requirements, subject to motor and system compatibility.
Procurement recommendation: Specify the complete -NA part number and request photographs of the nameplate, front panel, connectors, and revision markings. Confirm whether the required unit must support SFD3 or HIPERFACE DSL feedback. Since this model is discontinued, electrical testing and configuration verification should be part of the incoming inspection process.
