Product Description:
The S7480A-FBF2-F2 is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. It converts incoming three-phase mains power into precisely regulated motor current, enabling accurate torque and speed control in packaging lines, pick-and-place modules, and material-handling stages. By acting as the direct interface between a motion controller and the motor, the unit supports deterministic command execution in modern industrial automation cells. That arrangement supports consistent motor response during rapid starts, stops, and direction changes.
The drive accepts a three-phase input range of 208 to 480 V and is rated for 35 kVA of apparent power. During continuous duty, it supplies 48 Arms per phase, and dynamic moves can be covered with a peak output of 96 Arms. The power section exhibits a voltage slew rate of 4.8 kV/µs at 480 V and a residual drop of 6 V, which can affect cable screening and common-mode filtering. A minimum motor inductance of 0.88 mH is required for stable current control. Dual-channel STO allows safe shutdown without contactors. The cold plate cooling arrangement is supplemented by a fan-controller expansion card, and the option package includes cold plate hardware with coated printed circuit boards. The control electronics can be cycled up to 30 times per hour.
The cold plate weighs 10.4 kg and presents a maximum thermal resistance of 0.051 K/W at 480 V, so external chill plates or liquid loops can be sized accordingly. Heat flow from the power semiconductors peaks at 685 W at 480 V, and continued operation is permitted while the cold plate temperature remains below 75 °C. Acoustic output stays within 62 dB(A), which helps limit added noise in enclosed machine areas. The coated PCB finish helps resist conductive dust in industrial enclosures. The drive also uses noise-optimized fan control.
