DANAHER S20360-SRS Servo Drive – Resolver‑Feedback AC Servo Amplifier for Precision Motion

The DANAHER Motion S20360-SRS is part of the S200 series of digital servo drives, built for reliable control of brushless servo motors in compact machinery. One thing I appreciate is how this variant focuses on resolver feedback (the “SRS” suffix), which in many cases proves more robust than standard encoders in high‑vibration or high‑temperature environments. If you’re running AKM or similar industrial servo motors and want a straight‑forward, cabinet‑mounted drive with predictable tuning, this model typically checks the boxes.

Key Features

• Resolver feedback (SRS) – Stable performance in harsh conditions; typically less sensitive to electrical noise than incremental encoders.
• AC mains powered – Designed for 120/240 VAC, 50/60 Hz supplies, making it easy to drop into standard control cabinets.
• Compact, book-size footprint – Saves panel space and simplifies multi‑axis layouts; side‑by‑side mounting is common in many builds.
• Fast commissioning via RS‑232 – Simple setup and tuning through a service port; you can typically get a motor moving in minutes.
• Flexible command options – Supports common control modes like step/direction or ±10 V analog (depending on configuration), plus digital I/O for enable, fault, and limit logic.
• Encoder emulation outputs – A/B/Z signals for the controller when you need simulated position feedback from a resolver‑based system.
• Integrated protections – Over‑current, over‑voltage, over‑temperature protections that, from my experience, reduce downtime in most cases.

Technical Specifications

Application Fields

You’ll typically see the S20360-SRS in compact packaging lines, labeling and print registration, electronics assembly, small machine tools, test stands, feeders, and pick‑and‑place stations. One packaging OEM told us they like this resolver version because it keeps the axis stable near ovens and sealers where encoder noise used to be a headache.

Advantages & Value

• Reliability – Mature S200 platform; protections that, in most cases, reduce nuisance trips and service calls.
• Compatibility – Works well with DANAHER/Kollmorgen AKM motors and many third‑party BLDC servos using resolver feedback.
• Cost & lead time – Competitive pricing and short lead for in‑stock units; helps keep machine projects on schedule.
• Support – Commissioning help, parameter backups, and quick replacement options if you need to keep lines running.

Installation & Maintenance

• Cabinet & environment – Mount vertically in a ventilated cabinet; allow top/bottom airflow. Maintain clean, dry conditions within 0–40 °C.
• Power & grounding – Use dedicated circuit protection; earth bond the drive; separate power and signal wiring to minimize noise.
• Cabling – Use shielded motor and resolver cables; terminate shields at the drive end. Keep motor and feedback cables away from high‑power lines.
• EMI practices – A mains choke or line filter is often recommended; ferrites on I/O if the cabinet is electrically noisy.
• Routine care – Quarterly dust-out of the cabinet; check connector torque and ventilation paths. Firmware/parameter backups after any tuning changes.
• Safety – Verify STO/Enable wiring per your risk assessment; lockout/tagout before servicing; discharge bus capacitors before touching terminals.

Quality & Certifications

• Certifications – CE and UL/cUL are typical for S200‑series drives; RoHS compliance is commonly available. Certificates can be provided upon request.
• Warranty – 365‑day warranty from our side. Units are tested before shipment and packed for international transit.

From my experience, if you’re replacing an older S200 resolver drive, the S20360-SRS tends to drop in with minimal changes—usually a parameter file load, I/O check, and a quick tune. If you’d like, share your motor model and command source (PLC, motion controller, etc.), and I can suggest a safe starting parameter set.
