Product Description:

Kollmorgen's S60301-NA belongs to the S600 Servo Drives series. The unit functions as a power stage for brushless AC servomotors, converting controller commands into precisely regulated phase currents. By integrating with motion controllers, it closes torque and velocity loops in packaging machinery, robotics axes, and general automation equipment, delivering the regulated energy needed for repeatable position and speed control. Mounted inside a control cabinet, it ties together logic-level setpoints and three-phase mains within a single chassis.

The drive supplies a continuous phase current of 3 A rms; at this level, its heat sink releases 40 W that must be removed by forced ventilation. Two analog monitor outputs let a PLC observe internal variables, and two digital outputs provide fault or ready flags. The command input presents 20 kΩ of impedance to analog ground, minimizing loading on upstream DACs. Motor circuits up to 75 mH are accepted without additional reactors, and the PWM bridge switches at 8 kHz, which shapes current ripple. An output current form factor of 1.01 simplifies copper-loss calculations. The unit operates from 230 to 480 V three-phase mains, responds to a 10 V velocity setpoint, and leaves only a 5 V residual drop across its transistors.

For overload events, the power section can deliver 6 A rms for short durations, provided the connected motor has at least 12 mH of inductance to control di/dt. The installation rating of 2 kVA guides circuit-breaker sizing, while a quiescent draw of 15 W sets the standby heat load. The interface offers 4 optically isolated digital inputs for enable, reset, and user functions. An internal restart lock blocks unintended motion after mains recovery, and the design carries the AS electrical option. No expansion module is installed, so all features are available on the base board.
