Product Description:

The S30361-MN belongs to the S300 Servo Drives series manufactured by Kollmorgen. As a servo drive, it supplies regulated power to synchronous or induction motors so that motion sequences in automated machinery stay accurate and repeatable. By converting single-phase or three-phase mains power into a controlled DC bus and pulse-width-modulated output, the unit provides the velocity and torque commands that CNC tables, pick-and-place heads, or packaging axes require.

This model accepts a device input range of 110–230 V and delivers up to 3 A rms of continuous motor current, matching low- to mid-power servo stages. Inside, insulated-gate bipolar transistors switch at 8 kHz, and that carrier frequency affects speed-loop bandwidth and audible noise. The intermediate circuit is rated for a maximum of 450 VDC, giving margin for regenerated energy during rapid deceleration. Electrical loading on the mains side is held to 1.1 kVA, a figure used when sizing supply transformers and branch circuits. A current form factor of 1.01 indicates nearly sinusoidal motor current, which minimizes additional motor heating and helps the drive meet harmonic guidelines.

For braking cycles, the integrated resistor can absorb 20 W continuously, while 66 Ω of resistance shapes the peak energy it can dissipate without external hardware. Thermal losses inside the housing reach 35 W at rated current, so cabinet ventilation must extract that heat. Fast switching imposes a voltage rise of 3.3 kV/µs on the motor leads, making shielded cables important, and the drive supports machines with winding inductance of at least 4.3 mH. An STO safety input disconnects torque without removing power, and residual voltage drop across the output stage is limited to 4 V to enhance efficiency. Mechanically, the unit measures 70 mm wide, 171 mm deep, weighs 2.6 kg, and its noise emission stays under 25 dB(A), allowing dense panel layouts.
