- Product Introduction
Danaher S20260-VTS is a Kollmorgen S200 Series AC servo drive that controls the speed and torque of brushless servo motors. It accepts 120/240 VAC single- or three-phase input and delivers 1.5 ARMS continuous (4.5 ARMS peak) output for compact motion control applications.
This drive is chosen for its analog velocity/torque command interface, SFD and Hall feedback support, and compact footprint. It is widely used in industrial automation, robotics, and manufacturing equipment where precise velocity and torque control are required.

- Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power LED on drive | Input power missing or wrong voltage | ✅ High | Measure 120/240 VAC at L1/L2 terminals | Check input wiring and voltage before replacing the drive |
| Alarm LED flashing (overcurrent) | Motor short, bad wiring, or drive fault | ✅ High | Check motor phase resistance and continuity to ground | Replace motor/cable first; swap drives to isolate the fault |
| Motor does not run but no alarm | Command signal missing or wrong gain | ✅ High | Measure analog ±10 V command at the input | Verify command source and gain settings in the drive |
| Motor jitters or hunts | PID gains too high or feedback issue | ✅ Medium | Reduce velocity loop gains and check feedback wiring | Tune velocity loop and confirm SFD/Hall connections |
| Over-temperature alarm | Ambient >70 C or poor airflow | ❌ Low | Check cabinet temperature and heat sink cleanliness | Improve cooling and clean heat sink fins |
| Communication fault (if using MMC) | MMC card not seated or config mismatch | ✅ Medium | Reseat MMC card and verify config match | Confirm firmware and configuration compatibility |
If you are stuck, contact technical support with photos of the label, wiring, and alarm codes.
- Frequently Asked Questions (FAQ)
Q: Is S20260-VTS the same as S20360-VTS?
A: No. S20260-VTS is 1.5 ARMS continuous / 4.5 ARMS peak, while S20360-VTS is 3 ARMS / 9 ARMS peak.
Q: Can I use this drive with a 240 VAC single-phase supply?
A: Yes, the S20260-VTS accepts 120/240 VAC single- or three-phase input.
Q: Is this drive hot-swappable?
A: No. Power down the system before connecting or disconnecting the drive to avoid damaging the backplane or motor.
Q: What feedback types does this drive support?
A: It supports SFD (Smart Feedback Device) and Hall effect sensors for motor commutation and position feedback.
Q: Why is this cheaper than buying from Kollmorgen directly?
A: Most available stock is surplus or distributor overstock. The OEM channel may quote longer lead times, while secondary stock ships faster at a lower price.
Q: Do you test these before shipping?
A: A proper seller powers the drive, checks LED status, verifies command input response, and confirms no alarm codes. Ask for test results and photos of the front panel before you buy.
Q: What should I verify before ordering?
A: Confirm input voltage (120/240 VAC), current rating (1.5/4.5 ARMS), control mode (velocity/torque), and feedback type (SFD/Hall). That is where most install problems start.
Q: Is S20260-VTS still in production?
A: Yes, the S200-VTS family is still in production. However, specific units may be distributor stock with varying lead times.
