System compatibility
6SM77S-3000-G-09 belongs to Kollmorgen 6SM servo motor family,matched with Kollmorgen SERVOSTAR series servo drives,widely used in machine tools,packaging machinery,textile equipment and material handling systems.This is a legacy spare part for industrial equipment maintenance replacement.
Function
6SM77S-3000-G-09 is high-performance permanent magnet synchronous servo motor integrated with 24V DC holding brake.G suffix represents built-in power-off holding brake;09 stands for customized shaft and mechanical configuration.It features stable continuous torque and low cogging,suited for medium-load precision positioning.Resolver feeds back real-time rotor position to servo amplifier to realize closed-loop speed and position control.
Installation
Install 6SM77S-3000-G-09 via flange mounting.Align coupling accurately,connect power cable,resolver feedback cable and brake control cable.Tighten terminals and check cable shielding before power-on commissioning.Pay attention to the special shaft dimension marked by suffix 09.
Interface
‑Power cable connector
‑Resolver feedback connector
‑Brake 24V DC connector
‑Flange mounting interface
‑Customized shaft with keyway (09 version)
‑Shield grounding terminal
Circuit feature
Permanent magnet rotor structure,low loss stator winding,resolver position detection circuit,built-in permanent magnet brake coil,strong overload capacity,adapt to medium-load frequent start-stop working condition.
Feature
6SM77S-3000-G-09 is obsolete Kollmorgen spare part.Typical faults:bearing wear,winding insulation aging,resolver signal failure,brake coil burnout,shaft damage,connector corrosion.Inspect winding resistance,resolver signal and brake operation before replacement.
Diagnostic
When motor fails,motor overheat,abnormal mechanical noise,position deviation,resolver signal loss,overcurrent alarm,brake fails to release or lock,axis cannot run normally.
Built‑in function:Medium torque dynamic output,rotary position detection,power-off shaft holding,axis speed and position control,used as Kollmorgen machine tool servo motor spare replacement.

Product Brief
6SM77S-3000-G-09 is Kollmorgen 6SM series synchronous servo motor with resolver feedback and 24V holding brake,09 denotes special shaft variant.Match with SERVOSTAR servo drives.Verify shaft dimension,feedback type and brake function before ordering.ESD protection required during handling and installation.
