Product Description:

The S7480F-EIF2-S3 is a Kollmorgen drive in the S700 Servo Drives series. It functions as a closed-loop power stage that converts the plant’s AC mains into controlled motor currents so axes can accelerate, decelerate, and hold position according to motion controller commands. The unit fits into cabinets with three-phase mains supplies and is intended for general industrial automation where compact servo performance and modular field wiring are required.

The drive’s continuous phase current is 48 Arms, while momentary overloads can reach 96 Arms. At the mains terminals, it absorbs up to 35 kVA and operates across the full 208–480 V line range. Internally, power devices switch at 8 kHz, balancing current ripple against switching losses so torque remains smooth. Two analog input channels are available for velocity or torque reference signals, and discrete control is handled through 4 digital inputs plus 2 configurable I/O points on the drive and an additional 14 inputs with 8 outputs on the expansion EI board. A dedicated fan-controller card supervises cooling airflow to maintain device temperature under fluctuating motor load.

Total heat rejection under a 400 V supply reaches 635 W, and the integral fans limit acoustic output to 62 dB(A), so the cabinet can be located near operators. Safe Torque Off is provided through a dual-channel STO interface that removes gate-drive power when both channels are de-energized, supporting category 3 stop functions. During mains dips, the DC link loses only 6 V, limiting speed error until power recovers. A rated on/off cycling capacity of 30 starts per hour helps prevent premature contactor wear. Standard drives ship with conformal-coated circuit boards, and an available option adds fully coated PCBs to resist condensation or airborne contaminants.
