Brief Product Description

60WKS‑CE240/6PB is a rack‑mount analog servo amplifier from Kollmorgen Seidel 60WKS series. This 240V class four‑quadrant PWM servo drive is designed to drive SM‑series brushless synchronous servo motors with RLG rotor position sensor feedback. It integrates internal power supply, smoothing capacitors and ballast circuit for compact cabinet‑based installation. With differential analog setpoint inputs and relay‑based fault signalling output, it delivers precise torque and velocity control for legacy motion‑control equipment. Built for heavy‑duty industrial environments with comprehensive onboard protection functions. As an end‑of‑life automation spare, it is supplied as fully‑tested surplus and refurbished units for maintenance and retrofit of existing analog motion‑control systems.

Core Product Functions

• Four‑quadrant 3‑phase PWM power stage for bidirectional torque and speed control of synchronous servo motors
• Rated continuous output 6A, peak current up to 15A for maximum 5‑second overload operation
• Dual differential analog setpoint inputs for external speed / torque command signal reception
• RLG rotor position sensor interface for trapezoidal commutation of brushless servo motors
• Integrated power supply unit, smoothing capacitors and ballast resistor without extra external modules
• Built‑in protection: over‑current, DC‑link over‑voltage / under‑voltage, earth‑fault and power transistor thermal monitoring
• Isolated ready/standby relay contact for remote fault alarm and system status feedback
• Front‑panel LED indicators for DC‑link voltage status and general fault diagnostic indication
• Analog PI control loop for high‑response velocity and current regulation for precision motion tasks

Application Scenarios

• Legacy analog motion‑control systems equipped with Kollmorgen SM‑series brushless synchronous servo motors
• Machine‑tool feed axes, indexing equipment and high‑precision positioning automation machinery
• Packaging machinery, printing equipment and material‑handling production line servo control cabinets
• Special‑purpose industrial machinery requiring four‑quadrant analog servo drive performance
• Retrofit and maintenance of aging automation equipment based on 60WKS series servo platform
• Spare replacement servo amplifier for maintenance, troubleshooting and upgrade of existing Kollmorgen analog drive systems

FAQ (Frequently Asked Questions)

• Q: Servo motor runs abnormally or reports fault after installing 60WKS‑CE240/6PB?
  A: Check power‑supply wiring, RLG position‑sensor connection, analog setpoint signal, motor phase sequence and internal hardware fuse status.
• Q: Drive triggers frequent over‑current alarm during operation?
  A: Verify motor inductance matching, inspect motor winding insulation, check mechanical load jamming and adjust current‑limit potentiometer parameters.
• Q: Can this analog servo amplifier work with digital encoder‑only servo motors?
  A: No, it requires RLG rotor position sensor feedback; it cannot directly drive motors without compatible RLG signal interface.
• Q: Can 60WKS‑CE240/6PB communicate with modern PLC via fieldbus such as Profinet or EtherCAT?
  A: It is pure analog‑setpoint drive without digital fieldbus interface; control signals rely on analog voltage inputs only.
• Q: Is Kollmorgen 60WKS‑CE240/6PB available for brand‑new automation projects?
  A: This legacy analog servo amplifier has reached end‑of‑life. Only fully‑tested surplus and refurbished units are offered for existing‑site maintenance and retrofit tasks.
