Internal Product Review
The S7480C-SNF2-PA is a Kollmorgen S700 servo drive with coldplate cooling. A 48 Arms rated current and 96 Arms peak output current give the drive strong servo performance in higher-demand applications. Dual channel STO and an 8 kHz output stage frequency make this model a technically strong choice for precise, safety-conscious motion control.

Product Description:
The S7480C-SNF2-PA servo drive is produced by Kollmorgen as part of the S700 Servo Drives series. It is intended to regulate synchronous or induction servo motors in industrial automation systems that require precise torque and velocity loops. The unit integrates into coldplate-cooled control cabinets and supports a fan controller expansion card for auxiliary blower management. By converting three-phase mains power into controlled motor currents, the drive serves as the central power stage for packaging, machining, and material-handling axes.
At line supply voltages from 208 to 480 V, the drive draws up to 35 kVA and delivers a continuous phase current of 48 A rms; transient demands can be met with a peak capability of 96 A rms. This output range supports motor loads that require strong acceleration without exceeding the limits of the silicon or the DC bus capacitors. The internal IGBT bridge switches at 8 kHz, balancing acoustic noise with transistor losses while still supporting tight current loops. Cabinet integration uses coldplate cooling, and the aluminum mounting surface must remain within 25 µm per 100 mm of flatness so thermal transfer stays effective. The housing measures 190 mm wide, 244 mm deep, and 386 mm high, all measured without rear connectors.
Functional safety is addressed by dual-channel STO, allowing immediate removal of torque-forming pulses without external contactors. With power removed, residual DC on the output drops to 6 V, which helps reduce electric shock risk. When the drive is disabled, its electronics dissipate only 24 W, reducing heat load inside the cabinet during idle conditions. The aluminum housing weighs 10.4 kg, and coldplate operation keeps audible output at 62 dB(A) when measured 1 meter from the front panel. A fan-controller option can govern external blowers if forced-air assistance is preferred over the default passive coldplate arrangement.
