Product Description:

The S7480C-SNF2-S4 is an S700 Servo Drives series controller manufactured by Kollmorgen for high-performance motion systems. As an AC servo drive, it converts three-phase line power into regulated output that governs torque, speed, and position of industrial servomotors used on packaging lines, pick-and-place robots, and material-handling axes. The unit’s cabinet-mount profile, which is 190 mm wide, 285 mm deep, and 505 mm high with connectors, lets it fit alongside PLCs and safety relays, while its cold-plate base simplifies thermal coupling to a panel heat sink.

The drive delivers a continuous output of 48 Arms and accepts line voltages from 208 to 480 V, allowing one hardware type to cover a wide range of plant supplies. At rated conditions it draws up to 35 kVA, and the IGBT bridge is pulsed at 8 kHz so current ripple remains low even on high-bandwidth axes. The cold-plate version weighs 10.4 kg, which helps keep handling straightforward during installation. Acoustic emission tops out at 62 dB(A), which helps keep cabinet noise low during operation. The 1.01 form factor ratio supports dense stacking without obstructing airflow, and optional fan controller expansion hardware can be installed when forced ventilation is preferred over passive dissipation.

Functional safety is provided by the integrated dual-channel STO, which cuts motor energy without external contactors. This arrangement supports applications that need a built-in safety function without adding separate switching devices. During standby, internal circuitry dissipates 24 W of thermal loss, and residual DC voltage on the DC link falls to 6 V. The power stage is rated for up to 30 switching cycles per hour, a limit that helps protect semiconductor life in applications with frequent machine resets. The cold-plate option also supports liquid-cooled panels when ambient temperatures or enclosure loading require additional heat removal.
