Description
Product Overview
Kollmorgen S20360-SRS is a digital servo amplifier designed for industrial motion systems requiring accurate motor control, fast response, and flexible integration with automation controllers. As part of the Kollmorgen S200 servo drive family, the unit provides the electronic interface between a motion controller and a servo motor, regulating motor current based on position, velocity, and torque commands.
The Kollmorgen S20360-SRS is typically installed as part of a complete servo axis consisting of:
PLC / Motion Controller → S20360-SRS Servo Drive → Servo Motor → Feedback Device
The drive processes command signals from the controller and continuously adjusts motor operation through closed-loop feedback. This allows machinery to achieve controlled acceleration, accurate positioning, and stable torque regulation.
The S20360-SRS supports Kollmorgen’s S200 platform architecture and is designed for applications using brushless servo motors. The drive family supports AC and DC power configurations, with current ratings suitable for compact and medium-power motion axes. Depending on configuration, options such as SynqNet-based motion networking can be integrated for coordinated multi-axis applications.
Typical applications include automated assembly equipment, semiconductor machinery, packaging systems, robotics, machine tools, and industrial handling equipment. The drive’s performance depends heavily on correct motor selection, feedback compatibility, tuning parameters, and communication configuration.
For replacement projects, engineers should not match only the model number. Verify the complete drive configuration, including firmware revision, feedback option, motor model, application parameters, and communication interface. A replacement servo amplifier may require parameter restoration before the machine axis operates correctly.

Main Features and Advantages
S20360-SRS
Closed-Loop Servo Control
The primary function of the Kollmorgen S20360-SRS is closed-loop servo regulation.
The drive manages:
- Motor torque output
- Velocity control
- Position accuracy
- Dynamic response
The feedback loop allows the controller to compensate for load changes and maintain commanded motion.
High-Speed Current Regulation
The uses high-frequency current regulation technology to improve motor response during acceleration, deceleration, and changing load conditions. The reported current loop bandwidth is approximately 3–5 kHz.
This is important for applications requiring:
- Rapid indexing
- Precise positioning
- Smooth low-speed operation
- Controlled torque output
Intelligent Feedback Compatibility
The drive supports intelligent feedback systems that can store motor identification information.
Benefits include:
- Reduced manual parameter entry
- Faster commissioning
- Easier motor replacement
- Improved configuration accuracy
However, engineers should still verify stored parameters before returning equipment to production.
Flexible Motion Integration
The can be integrated into different automation architectures.
Typical interfaces include:
- Analog command control
- Encoder output applications

Engineer’s Guide: Field Pitfalls
⚠️ Confirm Motor Compatibility
Servo drives require correct motor matching.
Verify:
- Motor winding data
- Feedback type
- Encoder/resolver configuration
- Rated current
- Motor parameters
A similar-size servo motor may not operate correctly without proper tuning.
⚠️ Check Feedback Wiring
Many servo faults originate from feedback circuits.
Inspect:
- Encoder cable
- Connector pins
- Shield grounding
- Feedback device condition
Common symptoms:
- Position errors
- Encoder alarms
- Servo following faults
⚠️ Preserve Drive Parameters
Before replacement, save:
- Current loop settings
- Velocity loop parameters
- Position settings
- Motor identification data
- Communication settings
A factory-default replacement may require complete recommissioning.
⚠️ Verify Communication Option
If the system uses SynqNet or another motion interface, confirm the replacement drive has the same communication option installed.
A standard drive version may power up but fail to communicate with the machine controller.
⚠️ Refurbished Drive Testing Requirements
A proper evaluation should include:
- Visual inspection
- DC bus power test
- Control power verification
- Motor simulation test
- Feedback interface test
- Communication test
- Load operation verification
A drive that powers on is not necessarily ready for production service.
