Product Description:

The S7480A-SNF2-PA is a Kollmorgen motion controller supplied within the S700 Servo Drives series. As an AC servo drive, it regulates torque, speed, and position for synchronous or induction motors in automated machinery by converting three-phase mains power into a controlled output waveform. It is intended for machine axes that require closed-loop motor control, coordinated motion, and repeatable response during continuous industrial operation.

This unit operates across a line range of 208 … 480 V and can deliver a continuous phase current of 48 Arms, drawing up to 35 kVA from the supply under rated load. For analog interfacing, it presents an input resistance of 20 kΩ and re-transmits process variables through a programmable output of ±10 V. Safety is handled by dual-channel STO, while a dedicated RJ-45 SynqNet port links the drive to deterministic motion networks. A 15 Ω external brake resistor absorbs regenerated energy during rapid deceleration, and the residual 6 V drop across the power stage remains low enough to maintain dynamic response. Thermal management is supported by a fan-controller expansion card that activates cooling airflow once the internal heat sink temperature reaches 65 °C. Cold-plate construction with coated PCBs improves environmental tolerance, and the mounting surface must remain flat within 25 µm per 100 mm to ensure uniform heat transfer.

Mechanical dimensions include a height of 386 mm, a width of 190 mm, and a depth of 244 mm without connectors; total mass is 10.4 kg, which helps with cabinet layout planning. The output stage is clocked at 8 kHz, giving the control loop adequate bandwidth for precision tasks while limiting switching losses. An IP20 housing permits installation in clean electrical enclosures, and the cold-plate option supports base-plate cooling when air movement is restricted.
