Product Description:

The S7480A-FBF2-S4 is a controller in the Kollmorgen S700 Servo Drives series that regulates torque, speed, and position for AC servo motors in automated machinery. By converting the incoming three-phase supply into a high-bandwidth pulse pattern, the drive delivers precisely timed current to the motor windings for coordinated motion in packaging lines, robotics, and material-handling cells. It is suited for multi-axis systems that require accurate response during indexing, positioning, and speed-controlled operation. This control approach helps the drive maintain smooth acceleration and deceleration when the motor load changes during normal machine cycles.

This model operates over a supply range of 208–480 V and draws up to 35 kVA of input power. It provides a continuous output of 48 Arms and short-term peaks of 96 Arms. The output stage switches at 8 kHz, and electrical feedback is accepted through an FB-2-to-1 interface at X1 while the Safety 2-2 card monitors encoder consistency. Cooling is handled by a cold plate that mates the base to a cabinet heat sink, and a detachable fan-controller expansion card can be added when forced airflow is needed. The housing is 190 mm wide, 244 mm deep, and 386 mm high, which helps with cabinet layout and airflow planning.

Additional design options include a coated PCB package that protects circuitry against moisture and dust, matching the cold plate and coated PCBs build code. The protective coating helps the electronics resist contamination inside cabinets where dust or light moisture may be present. The drive can dissipate up to 8 kW of regenerative energy through its brake channel, and the factory-installed safety layer provides Dual channel STO for safety functions without external relays. When larger inertia loads stop, the onboard terminals support a brake resistor of 15 Ω to absorb excess energy. The assembly weighs 10.4 kg, which helps keep the unit stable against vibration after mounting.
