Product Description:

Kollmorgen produced the S7480A-FBF2-S3, an AC servo drive in the S700 Servo Drives series. The unit regulates torque, speed, and position for synchronous and asynchronous motors used in automated machinery and material-handling cells. By pairing with a motion controller over real-time fieldbus links, it converts incoming three-phase power into controlled current pulses that keep production axes accurate during acceleration, steady-state travel, and position corrections under changing loads.

The drive draws a maximum line power of 35 kVA and accepts a supply range of 208 to 480 V, so the same model can operate from multiple plant voltages. Under nominal conditions, it delivers 48 Arms of continuous output current to the motor windings, and a minimum phase inductance of 0.88 mH at 480 V helps keep current ripple within the limits of the S700 current loop. Internal losses appear as 685 W of heat that must be removed through the integrated cold plate, while acoustic emissions stay below 62 dB(A). Front-panel screw terminals can source 100 mA of 24 VDC logic power for relays, and the Fb-2-to-1 encoder socket supplies 5 VDC at 300 mA for high-resolution feedback devices.

Functional safety is built in, and the drive meets SIL CL3 and PLe targets by using dual-channel STO. The cold plate base and conformally coated PCBs support mounting against a liquid-cooled plate inside dusty or chemically aggressive cabinets, while the optional fan controller card enables forced-air support when the ambient temperature approaches the 65 °C F2 threshold. This arrangement reduces reliance on open cabinet airflow and helps protect exposed electronics in harsher indoor environments. With connectors installed, the housing measures 505 mm × 190 mm × 285 mm and weighs 10.4 kg, which helps cabinet layouts account for the space needed around power and feedback connections.
