Product Description:
The S60300-590 is a servo drive produced by Kollmorgen for the S600 Servo Drives series. It is intended for closed-loop motor control in industrial automation, converting the incoming mains supply into regulated, phase-accurate current that follows motion commands from a PLC or CNC controller. By managing torque and speed in real time, the drive enables precise positioning of rotary or linear axes used in packaging lines, material-handling stages, and automated assembly cells.
The power section accepts a three-phase supply ranging from 230 to 480 V and uses a control logic supply of 24 VDC. A current controller cycle time of 62.5 µs allows rapid compensation for load changes while the drive delivers a continuous output of 3 A rms and short-term peaks of up to 6 A rms. Two analog setpoint inputs and four programmable digital inputs provide flexible interface options for external control signals. A minimum load inductance of 12 mH and a maximum load inductance of 75 mH establish the permissible range for connected motor windings. An internal brake resistor rated at 66 Ω absorbs regenerated energy during deceleration, and the common-mode voltage is limited to 10 V to protect the insulation system. The output stage maintains a residual voltage drop of 5 V across its transistors.
At full load, the unit releases 40 W of heat, while its idle power draw is 15 W. The output current has a form factor of 1.01, minimizing additional rms heating in the connected motor windings. An input resistance of 20 kΩ relative to analog ground prevents excessive loading of upstream signal sources. Each axis has a rated installed load of 2 kVA, which supports appropriate sizing of transformers and circuit protection devices. Cabinet airflow must account for heat produced during continuous operation, particularly when several drives are installed close together. Adequate spacing around the unit also helps prevent heat accumulation near adjacent control equipment and wiring. The combination of low signal loading, controlled output current, and internal regenerative braking supports stable operation during repeated acceleration and deceleration cycles.
