Product Description:
The 60WKS-M240/22-PB is an analog servo amplifier manufactured by Kollmorgen and assigned to the 60WKS Analog Servo Amplifiers series. Installed in a control cabinet, it interfaces with a 240 V DC link and modulates motor phase current for brush or brushless axes in automated machinery. By regulating current internally, the unit supplies rapid torque commands that keep pick-and-place mechanisms, feeders, and small rotary stages synchronized with motion controllers.
The amplifier operates from a rated DC link of 240 V and can deliver a continuous output of 22 A to the motor windings. A current-loop bandwidth of 1 kHz allows tight torque tracking during fast profile changes. To prevent excess bus voltage, an internal ballast dissipates 135 W of regenerative energy under steady-state braking. Voltage lost across the output devices is limited to 5 V at rated current, conserving power for the load. The drive accepts command inputs through a 150 kΩ interface, and it is compatible with motors whose inductance is not less than 0.7 mH, helping keep current ripple within design limits. Mechanical dimensions of 220 × 233.4 × 45 mm permit narrow side-by-side mounting inside multi-axis racks.
During rapid deceleration bursts, the ballast can absorb up to 5.4 kW in pulse mode, after which bus voltage remains below the overvoltage ceiling of 325 V. Motor current quality is shown by an output form factor of 1.01, indicating that waveform distortion is negligible relative to the average level. Overall mass is only 1.4 kg, which simplifies panel installation and minimizes shock loading on DIN rails. Thermal dissipation reaches 140 W at rated current and 12 W in quiescent standby. The ballast engages at 300 V and drops out at 285 V, giving adequate margin to clamp transients while avoiding unnecessary heat production.
