Product Description:
The S30661-NA-105 is a servo drive manufactured by Kollmorgen as part of the S300 Servo Drives series. Designed for cabinet installation, it conditions line power, generates a controlled DC bus, and modulates output current for high-precision motion axes in industrial automation. The drive integrates control electronics, power switching, and safety circuitry, giving machine builders a compact component that converts single-phase or three-phase mains into a regulated three-phase motor supply while providing diagnostic feedback to higher-level controllers.
It accepts an input of 110 to 230 V and rectifies it to a DC rail that may rise to a maximum of 450 VDC; an internal comparator trips at 455 VDC to protect downstream components. Continuous motor excitation is supported by a rated output of 6 A RMS, and the power stage switches at a base carrier frequency of 8 kHz to balance acoustic noise and current ripple. Two analog command channels, four digital control lines, and an onboard CANopen interface support direct connection to sensors and PLCs. The device includes the functional safety feature STO (Safe Torque Off), which interrupts drive energy without opening the mains circuit. Mechanical dimensions measure 246 mm in height, 70 mm in width, and 171 mm in depth, enabling dense multi-axis mounting.
Its input stage is rated for 2.4 kVA, matching the thermal design of the switching devices and supporting regeneration through an internal path that can dissipate 80 W before external hardware is required. For rapid deceleration events, the built-in brake resistor presents 66 ohms and works in parallel with a heat sink section able to absorb 50 W of peak braking power. At a 50 percent duty cycle, the carrier can be increased to 16 kHz when lower torque ripple is needed. Protection against excessive bus energy is coordinated with the overvoltage threshold, and the converter mass of 2.8 kg keeps enclosure loads low during panel installation.
