Description
Product Overview
The Kollmorgen S20260-VTS is a compact brushless servo drive in the S200 Series, intended for applications that require controlled motor speed or torque through analog commands. The VTS designation identifies the base velocity/torque configuration, rather than the optional SynqNet or CAN/indexing configurations offered elsewhere in the S200 family. Its 1.5 A RMS continuous and 4.5 A RMS peak output ratings place it in the lower-current range of the series. The drive is intended for use with compatible brushless servo motors and feedback devices.
In a machine-control system, the Kollmorgen S20260-VTS receives command signals from the motion controller and regulates motor current to produce the requested speed or torque. Its documented feedback options include SFD and Hall sensors. The base VTS model uses analog control; an optional communications suffix should not be assumed to be present. This distinction matters when replacing a drive in equipment that relies on a specific fieldbus, encoder type, or motion-control interface. The motor’s electrical ratings, feedback wiring, command scaling, and drive setup must match the installed machine configuration.
For maintenance and procurement teams, the Kollmorgen S20260-VTS is a potential replacement candidate when preserving an existing S200 servo installation. Before ordering, confirm the complete model number, any customer-specific suffix, input power arrangement, motor feedback type, and control wiring. The S200 manual distinguishes several related models with different continuous and peak current ratings, so a physically similar unit may not provide the same motor-control capacity. Verify the drive’s condition and request evidence of power-up and functional testing before installation.artisantg.com+1
Product Introduction (Non-Templated)
When a servo drive fails, the replacement must match both the motor’s current demand and the machine’s command and feedback interfaces. The Kollmorgen S20260-VTS provides analog velocity/torque control with 1.5 A RMS continuous and 4.5 A RMS peak output capability.
Check the complete model suffix, motor feedback, and supply configuration before commissioning. A drive from the same S200 family is not automatically equivalent if its current rating or option hardware differs.

Related Products
The following drives belong to the Kollmorgen family. Their ratings and interfaces differ, so they should not be treated as automatic substitutes.
- S20360-VTS — Analog velocity/torque drive rated at 3 A RMS continuous and 9 A RMS peak. It has higher current capacity than the S20260-VTS.
- S20250-VTS — model for 120 VAC input or a specified voltage-doubler arrangement for 240 VAC single-phase operation. Check its input configuration before substitution.
- S20350-VTS — Higher-current model with a specific 120 VAC / 240 VAC single-phase input arrangement. Verify the motor and supply requirements.
- S20660-VTS — analog drive rated at 6 A RMS continuous and 18 A RMS peak. Its current capacity is substantially higher.
- S21260-VTS — model rated at 12 A RMS continuous and 30 A RMS peak for 240 VAC applications.
- S20260-SRS — drive configuration with an optional SynqNet card using RJ-45 connectors. The network interface differs from the base VTS configuration.
- S20260-SDS — drive configuration with an optional SynqNet card using Micro-D connectors. Verify connector type and motion-controller compatibility.
- S20260-CNS — configuration associated with CANopen/indexing functionality. It is not equivalent to the base analog VTS configuration without a system-level compatibility review.
Frequently Asked Questions
1. What is the Kollmorgen used for?
It controls a compatible brushless servo motor in analog velocity or torque mode. It is used in machine axes where the motion controller provides the required command signals and the drive closes the motor-control loop.
2. Can I replace the with an S20360-VTS?
Not automatically. The S20360-VTS has higher continuous and peak output-current ratings. Check motor current requirements, supply configuration, wiring, feedback type, and machine parameters before considering a replacement.
3. Can I hot-swap this servo drive while the machine is running?
Do not assume hot-swapping is supported. Servo drives have hazardous power circuits and may retain stored energy after input power is removed. Follow the manufacturer’s shutdown and discharge procedure, isolate the machine safely, and confirm that the axis cannot move unexpectedly before removing the drive.
4. Does the support firmware v3.1?
The available documentation does not establish a firmware v3.1 compatibility designation for this model. Confirm the drive’s hardware revision, setup software, and any applicable firmware information in the correct documentation before planning an upgrade.
5. Does the support SynqNet or CANopen?
The VTS suffix identifies the base analog velocity/torque configuration. SynqNet and CAN/indexing functions are associated with other option configurations, including SRS, SDS, and CNS. Confirm the complete part number and installed option hardware before connecting the drive to a networked motion controller.
6. Which motor feedback devices are compatible?
The -VTS documentation identifies SFD and Hall feedback support for the base drive. Confirm the motor’s exact feedback device, connector pinout, and electrical requirements before connecting it. Do not assume compatibility with EnDat feedback based solely on the family name.
7. What should I check when buying a replacement ?
Request photographs of the nameplate, connectors, model suffix, and any revision labels. Ask for test evidence covering power-up, fault status, command response, and motor feedback where practical. Confirm whether the unit is unused, used, or refurbished, and obtain written warranty terms before installing it.
