Product Description:

The S60300-NA is a servo drive manufactured by Kollmorgen and delivered within the S600 Servo Drives series. In an automation cell, it conditions and switches power to matched servo motors so that position, speed, and torque commands from a motion controller are reproduced accurately along the machine axis. By converting line power to controlled three-phase output while also supplying low-voltage control power, the unit serves as the active interface between the plant's electrical distribution and the motor windings.

The drive's control electronics are supported by an auxiliary supply of 24 VDC, with available control current rising from 1 A on systems without a motor brake to 3 A when a brake is present. Motor phase current can be delivered continuously at 3 A rms, and at this rating the internal power section releases 40 W of heat that must be carried away by panel airflow. Idle losses are limited to 15 W, which helps reduce cabinet temperature during standby. For precise torque regulation, the output current form factor is held to 1.01, indicating an almost perfect sinusoidal waveform. The power stage tolerates load inductances up to 75 mH while remaining stable, yet it can still drive machines whose motor-cable combination presents as little as 12 mH, giving flexibility when selecting motor cables or chokes. Input resistance to protective ground is 20 kΩ, which provides a defined reference for signal integrity.

Primary protection is provided by an AC line fuse rated at 6 AT, which complements electronic monitoring by disconnecting the unit under extended overload. The installed load that must be reserved inside the control cabinet is 2 kVA, a figure that incorporates conversion efficiency and peak demand. During power transfer, the residual voltage drop across the device is limited to 5 V, keeping motor terminal voltage close to the commanded 10 V reference. Line compatibility spans three-phase sources from 230–480 V, eliminating the need for autotransformers on most factory mains. Mechanical envelope height is 275 mm, allowing the drive to fit standard 300 mm deep enclosures without interference.
