Product Introduction
When a packaging line servo axis loses dynamic response accuracy during high-speed cyclic motion, the root cause almost always traces back to a generic servo drive that cannot maintain stable 8kHz high-speed switching under full 20Arms peak load.
Purpose-built for Kollmorgen SERVOSTAR 300 series motion control platforms, this compact digital servo amplifier supports both single-phase 115V–230V and three-phase 115V–230V universal power supply configurations. It delivers 10Arms continuous output current, with 20Arms peak current available for up to 5 seconds for demanding high-acceleration motion profiles. The 8kHz switching frequency and 3.3kV/µs dU/dt voltage rise rate at 230V enable ultra-smooth motor current waveform and exceptional dynamic performance. It natively integrates CANopen, RS232 and pulse-direction interfaces, eliminating the need for extra communication adapters during system commissioning.

Field Application & Technical Pitfalls
This part runs three non-negotiable production-critical roles.
First, it acts as the core servo drive for high-speed packaging line multi-axis motion systems, delivering precise position control for carton sealing and labeling axes with zero following error.
Second, it serves as the motion amplifier for CNC router and milling machine feed axes, supporting high dynamic response for complex 3D contour cutting trajectories.
Third, it functions as the servo control unit for robotic pick-and-place assembly stations, enabling fast and accurate part transfer cycles for electronics manufacturing lines.
⚠️ Peak Current Duration Overrun Risk: The 20Arms peak output current is only rated for maximum 5 seconds. If you continuously run the drive at 20Arms for longer than 5 seconds, you will trigger overcurrent fault and potentially damage the internal IGBT power stage.
⚠️ DC Bus Overvoltage Risk: The maximum allowable DC bus link voltage is 450V. If you connect the drive to a 480V AC power supply without a proper step-down transformer, you will instantly destroy the DC bus capacitors and power circuit.
⚠️ CANopen Baud Rate Mismatch: The default CANopen baud rate is 500kBaud. If your motion control master is configured for a different baud rate, you will never establish CAN communication with the drive.
I watched a senior motion control tech skip the peak current duration check last summer. He configured the drive to run at 20Arms continuously for a high-acceleration axis, and the drive triggered an overcurrent thermal fault after 10 seconds of operation. The team spent 1.5 hours troubleshooting before they found the peak current overrun issue. That 1-minute oversight forced the packaging line to stay offline for half a shift.
Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against Kollmorgen’s official SERVOSTAR 300 part revision database, run anti-counterfeit validation on the drive’s laser-etched serial label, and confirm no bulging DC bus capacitors or cracked solder joints on the IGBT power stage.
- Live Rig Testing: Mount the drive in a certified motion test rack, connect a Kollmorgen AKD series servo motor, and verify 4 hours of stable continuous 10Arms full-load operation.
- Parameter Testing: Confirm 8kHz switching frequency stability, verify 20Arms 5-second peak current performance, and validate CANopen, RS232 and pulse-direction interfaces all function correctly.
- Final QA & Packaging: Seal the fully tested drive in a static-shielding anti-static bag, apply a unique QC passed serial label, and pack it in ESD-dissipative foam with a printed hard copy of the full motion performance test report.
Frequently Asked Questions
- Can I hot-swap this drive while the motion system is powered on? No. Standard industrial servo drives do not support hot-swap. Pulling the drive live will cut all motor power instantly, triggering uncontrolled axis coasting and potential machine collision.
- What exact Kollmorgen motion systems does this part work with? It is fully compatible with Kollmorgen SERVOSTAR 300 series motion control platforms. It will not establish native stable communication with newer AKD2G series servo system controllers.
- How long is the standard warranty for this new surplus unit? It carries a full 12-month functional warranty. If it fails within that window under specified operating conditions, we cover all return shipping and bench replacement costs.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine units have the Kollmorgen hologram sticker on the side of the housing, and the IGBT power stage carries the official Kollmorgen part number marking. Refurbished clones usually skip the official hologram and use generic lower-rated IGBTs that cannot deliver the rated 20Arms peak current performance.
- Will this SERVOSTAR 310 directly replace an older Kollmorgen SERVOSTAR 300 series servo drive? No. Older SERVOSTAR 300 variants may have different firmware versions. You will need to re-import the full motor parameter and motion profile configuration via Kollmorgen WorkBench software after swapping.
- What’s the maximum safe continuous operating temperature at full 10Arms load? It will hold stable motion performance up to 55°C, though your mileage may vary if the control cabinet cooling airflow drops below 20 CFM and internal IGBT temperatures spike 15°C above ambient.
