Product Description:

The S7480A-PBF2-F2 is an S700 Servo Drives series unit manufactured by Kollmorgen and classified as an S700 Servo Drive. In an automation cell it functions as the power and control interface between a controller and a brushless servo motor, regulating current and voltage so position, speed, and torque follow machine commands with high precision.

This drive accepts a three-phase supply of 208…480 V, and its Slot 1 PROFIBUS interface exchanges setpoints and status with PLCs in real time. Continuous motor demand can be satisfied with 48 Arms while short bursts up to 96 Arms accommodate acceleration peaks. A power section rated at 35 kVA handles high inertia loads, and the output stage switches at 8 kHz to minimize current ripple. The residual voltage drop across the power devices is 6 V. Safety is provided by a dual-channel STO function that disables torque without removing mains power. A dedicated fan-controller expansion card governs the controlled fan option, and the “coldplate and coated PCBs” option detail pairs with a coated PCB finish to improve environmental resistance. All of these features operate together to keep thermal stress within limits while a PROFIBUS network command structure is maintained.

The coldplate cooling style mounts the power module to a machine heat sink, and the plate itself weighs 10.4 kg. Total thermal dissipation during full-load operation at 480 V is 685 W, and the measured thermal resistance of the assembly is 0.051 K/W, indicating a low temperature rise per watt. Physical dimensions support cabinet planning: depth without connectors is 244 mm, height is 386 mm, and width is 190 mm. Completing the specification set are a controlled fan for forced airflow, a coated PCB surface, and dual STO channels, all integrated to sustain reliable performance when space, heat, and functional safety must be addressed together.
