Product Description:
The S7480F-SNF2-S4 is a servo drive produced by Kollmorgen and assigned to the S700 Servo Drives series. It converts the three-phase power supply into regulated outputs for permanent-magnet motors, giving motion controllers high-bandwidth current and velocity loops for accurate servo response. By mounting in a cabinet, the unit links upstream PLCs to rotary or linear actuators, providing the thrust, speed, and position control required in automated packaging lines, pick-and-place stations, machine tools, and similar motion applications.
The power stage accepts an input range of 208–480 V and delivers a continuous phase current of 48 Arms; transient demands can be covered with a peak output of 96 Arms. A 24 VDC logic supply supports control functions, and a fan-controller expansion card helps keep internal temperatures within limits during operation. With a rated input of 35 kVA, the drive is sized for mid-to-large servomotors, while its switching devices commutate at 8 kHz to minimize torque ripple. SynqNet occupies Slot 1 for deterministic motion-network traffic, and the S2-2 safety board in Slot 3 enables safe-stop functions independent of the main control loop for coordinated axis control. The printed circuit boards are coated for added protection against airborne contaminants.
Peak current is available for 5 s, helping the system handle rapid accelerations before settling back to the rated envelope. Functional safety is enhanced through integrated dual channel STO, which removes drive energy without relying on external contactors. Regenerative energy during deceleration is dissipated through a brake resistor of 15 Ohm, and the electronics can source up to 8 kW of external brake power. The enclosure is 190 mm wide, 244 mm deep, and 386 mm high, and it weighs 13 kg, which supports vertical panel installation while leaving space for cable connectors and heat-sink airflow.
