Product Description:

The S7480F-EIF2-S4 servo drive manufactured by Kollmorgen belongs to the S700 Servo Drives series. Designed for high-performance motion axes, the unit converts three-phase mains power into regulated output for synchronous or induction motors in automated machinery. Within an automation cell, it acts as the power stage and safety interface, integrating safe torque-off channels and field-level I/O so controllers can command speed, torque, and position with millisecond accuracy.

Its continuous motor supply capacity is 48 Arms, a level chosen to match mid-frame servomotors without derating across the specified mains window of 208 to 480 V. During acceleration or rapid deceleration, the drive can deliver up to 96 Arms for several seconds, allowing the axis to overcome inertial peaks. The drive uses a bus converter rated at 35 kVA and switching devices that commutate at 8 kHz. Idle losses are limited to 24 W while acoustic output stays at 62 dB(A). Dual-channel STO disables gate signals in less than a millisecond for category-compatible safety stops, and an integral fan controller expansion card adjusts airflow once the internal temperature crosses set thresholds. The drive accepts three-phase supplies through coated power boards, and conformal coating resists condensation in humid production zones.

For machine control, the front terminal block exposes 14 digital inputs and 8 digital outputs. Each input senses 24 V at 7 mA, and every output can source 24 V at 500 mA to solenoids, relays, or sensor power rails. Boards are offered in standard or coated form, with the delivered unit marked as coated to increase resistance to flux residues. The aluminum housing measures 386 × 190 × 244 mm without connectors and weighs 13 kg, enabling panel mounting beside other S700 units while respecting the allowable noise envelope. At idle, the internal thermal dissipation of 24 W is removed by the speed-controlled fan described above, keeping semiconductor junctions below their rated limits.
