Product Description:

The S30661-NA-601-V070 is a Kollmorgen servo drive that belongs to the S300 Servo Drives series. It converts fixed-frequency mains power into a variable closed-loop supply for brushless servomotors. This allows precise velocity and position control on automated packaging lines, pick-and-place axes, and similar machinery.

Fieldbus integration is handled through the onboard CANopen interface, enabling parameter access and real-time status reporting from a PLC. The power stage accepts a single-phase or three-phase input of 110 to 230 V and delivers a continuous motor phase current of 6 A RMS. Its IGBT bridge switches at 8 kHz, balancing control bandwidth and electromagnetic compatibility, while short acceleration bursts can reach a peak output of 15 A RMS to overcome inertia. With a 2.4 kVA input rating, the supply wiring and circuit protection must be sized accordingly. Internal dynamic braking dissipates kinetic energy through a 50 W resistor and can be supplemented by an external 1 kW brake chopper when regeneration is higher. The drive also uses a reduced-current mode that shifts the carrier to 16 kHz to lower audible noise after the load settles.

The DC link is rated for a maximum of 450 VDC, and an overvoltage shutdown activates at 455 VDC to protect the bus capacitors. Machine safety is supported by the dual-channel STO input, which removes torque without opening mains contactors. Heat produced by switching losses and control electronics reaches a steady dissipation of 60 W, so cabinet airflow must maintain acceptable ambient temperatures. Motor compatibility starts at a minimum winding inductance of 2.6 mH, which keeps current ripple within servo loop tolerances. A residual voltage drop of 4 V across the output stage and a voltage rise speed of 3.3 kV/µs are also part of cable and insulation planning.
