Product Description:
The S7480F-SEF2-NA servo drive is manufactured by Kollmorgen as part of the S700 Servo Drives series. The unit is intended to regulate torque and speed in automated machinery by supplying controlled three-phase power to synchronous or induction motors. With integrated safety and fieldbus connectivity, it serves as a compact controller inside cabinets where thermal and electrical coordination with motors is required in motion axes. Its part designation, S7480F-SEF2-NA, identifies hardware options, current class, and regional settings within the product family.
The drive’s power section is sized for continuous loads up to 35 kVA, allowing it to deliver the rated output under normal ventilation. The unit accepts incoming mains from 208 to 480 V and switches at 8 kHz, a carrier frequency that balances heat dissipation with current ripple. Nominal phase current reaches 48 Arms, and conduction losses are held to a residual voltage drop of 6 V. Protection against accidental contact is provided by the IP20 housing, while the enclosure measures 190 mm in width, 244 mm in depth, and 386 mm in height without connectors. An output current form factor of 1.01 indicates the sinusoidal quality of the motor current, and these dimensions suit 300 mm-deep cabinets.
For dynamic demands, the inverter supplies a peak of 96 Arms for 5 seconds, after which thermal limits return it to the rated value. Safe torque interruption is handled by the integrated dual-channel STO circuit, so external contactors are not required. Motion commands and diagnostic data are exchanged through the Slot 1 interface, which uses the real-time SERCOS II bus. Acoustic emission is limited to 62 dB(A) at full load, and cooling air is directed by an expansion card fan controller. The unit is fitted with coated circuit boards and weighs 13 kg.
