KOLLMORGEN 60WKS-CE24022PB
Product Name: 60WKS Analog Servo Amplifier, 240 V DC Link, 22 A
Product Introduction: This transistorized analog servo amplifier converts a fixed DC bus into controlled three-phase current for brushless or brushed servo motors, providing torque, velocity and four-quadrant regeneration control in industrial automation axes.
Detailed content
Technical Specifications: Rated DC-link voltage 240 V, rated output current 22 A continuous, peak output 50 A, installed load 3.7 kVA, AC supply range 3×60–172 V AC 50/60 Hz for the M-platform equivalents, protection class IP00, weight 1.4 kg, dimensions 220×233.4×45 mm double Eurocard 9 TE.
Control And Feedback: Analog setpoint ±10 V, subordinate current loop bandwidth 1 kHz, output-stage clock 2×8.5 kHz, auxiliary ±15 V for RLG/tacho and control electronics, optional 24 V auxiliary 20–30 V, DIN 41612-C64 control connector, DIN 41612-D32 power connector, 9-pin Sub-D RLG/tacho connector.
Protection And Ballast: Overvoltage trip 325 V DC, ballast switch-on 300 V, switch-off 285 V, continuous ballast 135 W, pulse ballast 5.4 kW, AC fusing maximum 3×20 A, minimum motor inductance 0.7 mH, quiescent dissipation 12 W, dissipation at rated current 140 W.
Performance Parameters: Four-quadrant operation, 22 A continuous/50 A peak for approximately 5 s, low current ripple through 8.5 kHz dual-edge modulation, regenerated energy absorbed by internal ballast resistor.
Materials And Structure: Double Eurocard PCB, power transistor bridge, DC-link capacitors, ballast resistor assembly, heat-sinking/panel-mount mechanical format, IP00 open construction for cabinet use.
Working Principle: The amplifier receives an analog command, closes the inner current loop, modulates the transistor output stage at the specified switching frequency and delivers phased current to the motor while returning regenerative energy through the ballast circuit.
Application Scenarios: Packaging lines, pick-and-place stations, machine-tool axes, robotics and general multi-axis servo systems using analog command architecture.
Installation Requirements: Mount vertically in a closed switchgear cabinet with uninterrupted airflow, provide forced ventilation for high-current or high-ambient operation, secure the Eurocard to the rack/heat sink, separate power and signal cabling, set AC fusing to 3×20 A maximum and confirm 240 V DC-link compatibility.
Usage Notes: Verify motor inductance above 0.7 mH, tacho/RLG polarity and analog scaling before enable. Maintain cabinet temperature 0–45°C at rated data; apply 2.5 percent per °C derating from 45°C to 55°C with forced ventilation. Do not operate without cabinet protection due to IP00.
