Product Description:

The 60WKS-M240/06-PB analog servo amplifier is produced by Kollmorgen as part of the 60WKS Analog Servo Amplifiers series. Designed for industrial automation, the unit interfaces between a motion controller and a DC brush-type or brushless synchronous motor, modulating current so that commanded torque tracks load demands with minimal delay. By converting a stabilized DC link into a controlled four-quadrant output, it supports bidirectional speed and regenerative braking, allowing precise positioning and velocity loops in machine tools, packaging lines, and material-handling axes. The analog control architecture is suited to systems that use conventional velocity or torque commands rather than a digital network. Its internal electronics draw only 12 W at idle, limiting cabinet heat rise.

Rated DC-link voltage is 240 V DC. During continuous four-quadrant service, the amplifier delivers 6 A and can furnish 15 A for short peaks. An 8.5 kHz output-stage clock shifts switching noise beyond the acoustic range, and a 1 kHz current-loop bandwidth preserves stiff torque control. The command input has an impedance of 150 kΩ and accepts a ±10 V signal. Auxiliary power of ±15 V is provided for sensors, and the link-to-phase voltage drop is limited to 5 V.

Protection and energy management are addressed through an overvoltage shutdown threshold of 325 V, preventing damage from regenerated energy when high-inertia loads decelerate. Excess kinetic energy is redirected to a ballast circuit that can absorb up to 5.4 kW, with the ballast engaging once the DC bus reaches 300 V. The supply side requires an installed load of 1 kVA, and motor windings connected to the amplifier should present at least 2.5 mH of inductance so that ripple current stays within safe limits for both copper and magnetic components. This helps keep motor current stable during acceleration and deceleration. Line protection is achieved with three 20 A AC fuses installed ahead of the rectifier.
