KOLLMORGEN 60WKS-CE240/6PB Analog Servo Amplifier

Product Description

KOLLMORGEN 60WKS‑CE240/6PB is an analog servo amplifier from Kollmorgen‑Seidel 60WKS series, manufactured in Germany. This series is OEM discontinued and mainly circulated as industrial spare‑parts for legacy machines. Model decoding: CE = analog control variant; 240 = 240 V DC‑link; 6 = 6 A rated output; PB = position‑board expansion slot.

It is a 4‑quadrant power stage for brushless servo motors, controlled by ±10 V analog speed / torque command. Built‑in chopper circuit works with external braking resistor. Comprehensive hardware protections include short‑circuit, over‑current, over‑voltage and over‑temperature. Front‑panel red/green LEDs indicate DC‑link status and general faults. Optional PB position board adds position‑loop capability. PI current‑loop and speed‑loop regulators can be tuned via potentiometers. Rack‑mount design. Widely deployed on legacy machine‑tools, printing and metallurgical machinery. Surplus‑new and tested‑refurbished units are available on marketManualsLib.
