Product Description:

The S30661-FN is a servo drive manufactured by Kollmorgen within the S300 Servo Drives series. It conditions mains power, distributes regulated current to a matched servo motor, and executes real-time control loops that keep industrial axes synchronized with a machine’s command profile. By integrating signal processing, bus power management, and a controlled fan for forced-air cooling, the unit supports compact installation in packaging, handling, and general automation cells that require precise position and torque regulation.

The power section accepts a single-phase or three-phase input of 110–230 V, and an auxiliary 24 VDC rail energizes the control electronics for safe startup and shutdown. During continuous operation, the inverter supplies 6 A rms to the motor while drawing a maximum of 2.4 kVA from the line. Pulse-width modulation is generated at 8 kHz, a carrier frequency that balances acoustic noise with switching losses. Command execution is driven by a position loop that updates every 250 µs, so incremental encoder feedback can be processed with minimal latency. The step-and-direction interface tolerates signal rates up to 100 kHz, and the residual voltage drop across the power stage is limited to 4 V, reducing unnecessary heat.

Dynamic events are handled with a peak current of 15 A rms, while the DC bus can rise to 450 VDC before the overvoltage clamp engages at 455 VDC. An internal brake resistor of 66 ohms dissipates up to 50 W of regenerative energy, supplementing the 60 W of thermal dissipation at rated load. The integrated safety circuit provides STO, eliminating uncontrolled torque when the channel is asserted. A controlled-fan cooling path stabilizes component temperature, and the 70 mm width and 171 mm depth without connectors allow dense rack mounting alongside other S300 drives.
