Product Description:

The 60WKS-CE240/12PB is an analog servo amplifier built by Kollmorgen for the 60wks Analog Servo Amplifiers series. Positioned between a motion controller and a servo motor, it shapes command signals into regulated current so that industrial axes accelerate, decelerate, and hold position with predictable behavior. By converting low-level reference inputs into controlled high-power outputs, the unit fulfills a core function in automated packaging, material-handling, and machine-tool systems.

This amplifier runs on a DC bus of 240 V and delivers a continuous output of 12 A, while transient demands can draw up to 30 A. A current-loop bandwidth of 1 kHz lets the drive correct error quickly, and its output stage is clocked at 8.5 kHz to minimize ripple torque in low-inductance motors. The installed electrical load is 2 kVA, protected on the mains side by 3 × 20 A fuses. Internally the electronics dissipate 85 W under rated conditions, assisted by an auxiliary ±15 V/±20 mA supply for external sensors. For motor compatibility, the amplifier expects a minimum winding inductance of 1.2 mH and enforces a 325 V over-voltage shutdown so drive components are not stressed beyond dielectric limits.

The energy management stage features a ballast network that switches in at 300 V and disconnects at 285 V; during braking it can absorb 5.4 kW in pulses and 135 W continuously, preventing DC-link rise toward the trip threshold of 325 V. Mechanical integration is simplified by an envelope of 220 × 233.4 × 45 mm, allowing high-power density inside compact cabinets. Drive-to-motor matching is safeguarded by the specified minimum inductance of 1.2 mH, ensuring that the 1 kHz current loop remains stable across the intended torque range.
