Product Description:

The 60WKS-CE240/3PB is an analog servo amplifier produced by Kollmorgen as part of the 60WKS Analog Servo Amplifiers series. The module feeds controlled current to a matched servomotor and closes the torque loop, enabling coordinated motion axes in packaging lines, robotics, and machine tools. It interfaces between the motion controller and the motor, translating low-level command voltages into high-bandwidth current for precise response during start-stop cycles.

In operation, the amplifier draws energy from a regulated 240 VDC supply on its DC link. Within its linear output stage, a current loop stabilizes at 1 kHz, allowing the controller to modulate motor torque without noticeable delay. Continuous axis loading is supported by a rated output of 3 A, while short acceleration bursts can be handled with a peak capacity of 7.5 A before foldback occurs. To minimize acoustic and electrical ripple, the PWM section switches at 8.5 kHz, helping keep current ripple low enough to avoid excess winding heat or interference with position encoders. These timing and current characteristics support medium-inertia motors during fast indexing moves in pick-and-place systems.

The internal ballast can absorb regeneration surges up to 5.4 kW, and an overvoltage circuit disconnects the link at 325 VDC to protect both the amplifier and the rectifier. High-impedance command inputs of 150 kΩ minimize loading on upstream analog controllers, so low-power DAC cards can be used without signal distortion. The housing measures 220 × 233.4 × 45 mm, fits on a 45 mm DIN rail, and weighs 1.4 kg, which supports dense cabinet layouts. During steady operation, the unit dissipates 30 W and drops to 12 W at idle, while a 5 V drop at rated load helps estimate cable losses. Compatible system selection must also account for the minimum motor inductance of 5 mH, the 0.5 kVA installed load, and the recommended three-pole 20 A fuses.
