KOLLMORGEN 60WKS-M24022
Product Name: 60WKS Analog Servo Amplifier, 240 V DC Link, 22 A
Product Introduction: This transistorized analog servo amplifier delivers high-current closed-loop control for brushless synchronous servo motors in heavy-duty industrial motion axes, supporting torque, velocity and four-quadrant regenerative operation.
Detailed content
Technical Specifications: Rated DC-link voltage 240 V, rated output 22 A continuous, peak output 50 A for approximately 5 s, installed load 3.7 kVA, minimum motor inductance 0.7 mH, protection class IP00, weight 1.4 kg, dimensions 220×233.4×45 mm double Eurocard 9 TE.
Control And Feedback: Analog setpoint ±10 V, current-loop bandwidth 1 kHz, output-stage clock 2×8.5 kHz, auxiliary ±15 V for RLG/tacho, optional 24 V auxiliary 20–30 V, DIN 41612-C64 control, DIN 41612-D32 power, 9-pin Sub-D RLG/tacho.
Protection And Ballast: Overvoltage trip 325 V, ballast switch-on 300 V, switch-off 285 V, continuous ballast 135 W, pulse ballast 5.4 kW, AC fusing maximum 3×20 A, dissipation at rated current 140 W, quiescent dissipation 12 W.
Performance Parameters: Four-quadrant 22 A continuous/50 A peak, regenerative braking through ballast, low-ripple current output, compatible with Kollmorgen SM-series brushless motors using tacho/RLG feedback where the configuration matches.
Materials And Structure: Double Eurocard PCB, power transistor bridge, DC-link capacitors, ballast resistor, open IP00 construction for cabinet/heat-sink mounting.
Working Principle: The amplifier accepts an analog command, closes the current loop, modulates the output transistors at 8.5 kHz dual-edge rate and returns decelerating energy to the ballast circuit while maintaining motor torque response.
Application Scenarios: Heavy CNC axes, multi-axis machine tools, large packaging systems, material-handling drives and retrofit servo racks using 60WKS analog architecture.
Installation Requirements: Mount vertically in a closed cabinet with forced ventilation for 22 A operation, secure to heat sink/rack, provide 3×AC isolation and 3×20 A maximum fusing on the supply side, verify 240 V DC-link and backplane compatibility.
Usage Notes: Confirm the exact suffix configuration because 60WKS-M24022, M240/22 and M24022-PB option sets differ in connectors, enable logic and feedback. Verify tacho polarity, motor inductance above 0.7 mH and thermal derating: 0–45°C rated, 2.5 percent per °C derating 45–55°C with forced ventilation.
