Product Description:

The 66WKS-M310/45-V1 is an analog servo amplifier produced by Kollmorgen as part of the 60wks Analog Servo Amplifiers series. It receives command signals from a motion controller and converts them into precisely regulated motor current, enabling closed-loop torque control in pick-and-place gantries, indexing tables, and other automated axes. Operating between a DC link and the motor windings, the amplifier forms the intermediary power stage that balances dynamic responsiveness with protection of upstream control electronics.

A current loop bandwidth of 1 kHz lets the internal control circuit correct torque deviations within one millisecond, while the output stage is switched at 8.6 kHz to minimize ripple in the motor windings. The DC-link is stabilized at 310 VDC, and the unit can deliver a continuous phase current of 45 A with short-term surges up to 100 A during rapid acceleration. Protection features include an overvoltage cutoff at 410 V and a voltage drop of 5 V at rated current that must be factored into bus sizing. The control interface is provided through a DIN 41612-C64 connector, the power interface through a DIN 41612-E48 plug, and the output current form factor of 1.01 keeps RMS heating almost identical to the average value.

Thermal and installation figures define service life. At full load the amplifier dissipates 330 W, falling to a quiescent loss of 20 W when idle, and it draws an installed load of 9.6 kVA from the facility mains. Motors with inductance no lower than 0.8 mH are required so the H-bridge operates within its current ripple limits. The housing measures 220 × 233.4 × 91 mm and, including heat sink and connectors, weighs 2.8 kg, permitting dense rack mounting next to other drive modules.
