Product Introduction
This Kollmorgen S21260-SRS is a compact brushless servo drive from the S200 family, fitted with SynqNet for synchronized multi-axis motion. It closes position and velocity loops and outputs regulated current to paired brushless servo motors.
It maintains tight axis synchronization across multi-axis machine layouts. Many machine builders keep spare units because full platform migration requires redesigning the motion controller network and rewiring the machine.

Application Scenarios & Field Experience
This SynqNet drive is a single point of failure for coordinated motion sequences. A fault stops the full axis group, and most automated machines cannot run partial cycles without position interlocks.
- Semiconductor automation: Wafer handling stages with synchronized pick-and-place axes
- Packaging machinery: Multi-axis carton forming and sealing motion systems
- Electronics assembly: PCB routing and dispensing stations with tight positioning tolerances
- Medical automation: Precision test and handling equipment for lab diagnostic devices
I supported a packaging machine downtime event where this drive threw a bus fault and dropped its axis. The remaining axes halted on interlock, and the line could not advance product. We installed the spare S21260-SRS, loaded the saved axis parameter set, and re-established SynqNet sync in 24 minutes. The line avoided a multi-hour production hold.
Standard Operating Procedure (SOP) for Quality Control
- Visual & Origin Inspection: Verify OEM marking, terminal screw integrity, D-Sub and RJ45 connector condition, anti-counterfeit checks; reject units with burned power terminals or unapproved board rework.
- Live Rig Testing: Apply rated AC input, connect to a test servo motor, run current loop calibration, confirm SynqNet link and fault-code reporting.
- Firmware Verification: Read and log drive firmware version; share this record so buyers can match existing motion controller firmware.
- ESD-Safe Packaging: Seal the drive in static shielding bag, add foam around connectors and heat sink fins, label cartons for ESD and shock protection.
Frequently Asked Questions (FAQ)
Q1: Can I drop this S21260-SRS into any S200 machine without pre-checks? A: Confirm your motion controller firmware and SynqNet node configuration first. Older controller firmware releases may not recognize newer drive firmware builds. Q2: What warranty coverage comes with this part? A: We provide a 12-month warranty starting from delivery date. Warranty covers factory defects; overcurrent damage, wiring shorts, or incorrect motor parameter tuning are excluded. Q3: How quickly can this unit ship once I place an order? A: If marked in stock, we pack and ship within 1 business day. We confirm stock before payment, as legacy SynqNet servo drives are no longer active production. Q4: What risk occurs if drive firmware differs from the rest of the SynqNet node group? A: Mismatched firmware can cause axis drift, dropped sync frames, or random network faults. Send your current drive firmware revision before ordering. Q5: Can I hot-swap this servo drive while the machine main power stays energized? A: Do not hot-swap. Disconnect AC input and confirm the DC bus capacitor bleeds down before removal. Hot removal can damage the SynqNet bus and adjacent drives on the same network.
