Product Description:

The S7480F-SNF2-S3 servo drive is manufactured by Kollmorgen as part of the S700 Servo Drives series. It modulates three-phase power for brushless servomotors, enabling accurate speed, torque, and position control in automated assembly lines, conveyors, and packaging equipment. The unit accepts common factory supply voltages and includes built-in safety and communication hardware that reduces the need for separate external modules in a control cabinet.

Electrically, the drive is rated for a continuous motor current of 48 Arms, with transient motion bursts supported up to 96 Arms. The input section can absorb up to 35 kVA from mains lines operating between 208-480 V, allowing the same model to serve both lower-voltage and higher-voltage plant systems. Its IGBT output stage switches at 8 kHz, which helps reduce motor acoustic noise and improve current-loop resolution during operation. During conduction, the residual voltage drop is 6 V, which should be considered when matching the drive to the supply and motor combination. Internal airflow is managed by a dedicated fan-controller expansion card, and the drive uses a coated printed circuit board to help protect conductive traces against condensation and airborne contaminants.

Mechanical energy dissipation is supported by a built-in brake chopper capable of handling 8 kW continuously, while an external brake resistor of 15 ohms can be connected when additional thermal capacity is needed. The onboard safety card provides one dual output, seven single outputs, and nine inputs for integration with machine safety circuits and field devices. It reacts to diagnosed errors in 2 ms, allowing protective functions to respond quickly during a fault condition. Safe torque off is implemented as a dual-channel STO architecture so that independent channels can be supervised by a safety controller. Two RJ-45 SynqNet ports support real-time motion networking, and a 15-pin D-Sub connector carries 24 V digital I/O for local sensors and actuators.
