Product Description:

The S7480A-EIF2-NA servo drive is produced by Kollmorgen and belongs to the S700 Servo Drives series. Designed for motion control tasks in industrial automation, the unit governs torque, speed, and position of synchronous or asynchronous motors while interfacing with higher-level controllers through its onboard CANopen and EtherCAT buses. A coldplate baseplate allows integration into liquid-cooled panels, so the device can be mounted adjacent to other heat-generating equipment without forcing airflow across delicate electronics.

Its power section operates over a wide supply of 208–480 V three-phase AC and delivers a continuous output current of 48 Arms, supporting temporary surges up to 96 Arms when high acceleration is demanded. Converter and inverter stages are sized for 35 kVA of apparent input power, and an output stage carrier frequency of 8 kHz minimizes motor acoustic noise while maintaining current resolution. Functional safety is addressed through a dual-channel STO input that removes drive energy in emergency stop conditions. The internal design limits the residual DC bus voltage to 6 V after shutdown, and an external 15 Ohm brake resistor can be connected to absorb regenerative energy. Cooling is handled entirely by the coldplate, while an optional fan-controller card supports cabinet air movers when additional convection is required.

The drive housing uses coated PCBs for enhanced moisture resistance, and the board finish is coated. When idle, the electronics dissipate only 24 W, reducing enclosure cooling demand and extending component life. Maximum audible noise remains below 62 dB(A) even when auxiliary fans are active. Overall dimensions measure 386 mm in height, 190 mm in width, and 244 mm in depth without connectors, allowing placement in compact control racks. The device weighs 10.4 kg with the coldplate fitted, and the coldplate interface keeps semiconductor temperatures stable by transmitting heat directly to a panel or liquid circuit.
