Product Details:

KOLLMORGEN 64WKS-M240/6-PO is a compact four-quadrant transistor servo inverter belonging to the Seidel 64WKS series, the PO suffix represents pulse command interface configuration. This unit is designed for small and medium feed axes of CNC machine tools and special automation equipment, built-in PI current loop and speed loop regulator, delivering stable low-current output and rapid dynamic response for light and medium load positioning axes that require smooth speed adjustment. It is widely used for auxiliary feed axes, marking equipment and small synchronous motion units in metal processing machinery.

This servo amplifier supports resolver and encoder feedback signals to collect rotor position and speed data of matched Seidel servo motors, forming complete closed-loop motion control. It adopts 19-inch rack mounting structure with stud bolt power terminals and dedicated PO pulse signal connector, convenient for system wiring and multi-drive combined installation inside the electrical cabinet. Internal power stage integrates comprehensive protection functions including overcurrent, overvoltage, undervoltage and overtemperature, with LED status indicators and fault alarm output terminals for convenient on-site troubleshooting and maintenance. The small rack footprint helps to optimize cabinet layout when multiple drives are arranged together.

Technicians can tune speed loop gain, current limit and braking parameters according to different load characteristics. Continuous real-time monitoring of DC bus voltage and output current is implemented inside the drive. Once faults such as overload, overheating or feedback signal loss are detected, the amplifier will immediately disable power output and trigger alarm, preventing servo motor burnout and mechanical collision. The robust mechanical structure offers good vibration resistance, adapting to long-time continuous operation in industrial workshop conditions.

This KOLLMORGEN 64WKS-M240/6-PO servo amplifier has been discontinued by the original manufacturer. It is provided as a tested aftermarket replacement spare part for legacy Seidel motion control systems. Maintenance staff can perform replacement safely after power cut, and the original control logic and wiring layout can remain unchanged.

It is a classic low-current rack-mounted Seidel drive spare part, commonly used for maintenance and retrofit of old CNC machine tool auxiliary axes.
