Product Description:

The S7480C-FBF2-PA is a servo drive manufactured by Kollmorgen as part of the S700 Servo Drives series. Serving as the power interface between the AC mains and a servomotor, it converts a 208–480 V supply into controlled three-phase output while reading multiple feedback channels. The drive is intended for motion axes that demand compact cold-plate mounting inside machinery where forced-air cooling is handled externally.

Signal processing occurs quickly: the analog command inputs are updated every 62.5 µs, and the ±10 V monitor output is digitized with a resolution of 0.38 mV, allowing fine velocity or torque trim. During acceleration, the inverter can deliver a peak phase current of 96 Arms, while continuous operation is supported at 48 Arms. These current ratings apply across the drive's input range, so the same unit can be used on low- or high-voltage installations without rewiring. The FB-2to1 module supplies secondary encoder power at 5 VDC and accepts up to 300 mA, enabling dual-loop operation when mechanical compliance must be reduced. PosI/O-Monitor resources expose position latches and fault bits to the PLC, supporting fast diagnostics.

For thermal management, the unit fastens to a machined cold plate; the mounting surface must stay within a flatness of 25 µm over 100 mm, and its center temperature may not exceed 75 °C. An internal fan controller card turns the heat-sink blower on once the fin temperature reaches 80 °C, while overall idle losses remain at 24 W. With a supply demand of 35 kVA under rated load, the drive still weighs only 10.4 kg, helping reduce cabinet mass. The integrated dual-channel STO interface satisfies functional safety shutdown requirements, and all option boards share the same rear slot so the cold-plate outline is unchanged. Installation is simplified because the cold-plate option and top-mounted fan share the same fastener pattern.
