Product Description:

The S7480F-PNF2-S3 servo drive is manufactured by Kollmorgen and belongs to the S700 Servo Drives series. Acting as an intermediate converter, it receives three-phase mains power and delivers conditioned current to synchronous servomotors, letting machines control torque, speed, and position with millisecond precision. The unit integrates signal processing, power electronics, and built-in safety features so motion axes can be packaged compactly inside modern automation cells. It is suited for coordinated motion tasks in packaging, indexing, and material-handling equipment where repeatable axis response is required.

The electrical stage is sized for a continuous output of 48 Arms, while transient surges can reach 96 Arms. A supply range of 208 to 480 V and an input capacity of 35 kVA suit medium-power applications fed from standard plant distribution. Internal IGBTs switch at 8 kHz, keeping motor current ripple low, and when the drive is disabled, heat loss falls to 24 W. Regenerative energy is diverted to an 8 kW brake resistor matched to 15 Ω, which helps prevent DC-link overvoltage during rapid deceleration. Cooling is handled by a controlled fan that is monitored by a dedicated expansion card, and printed circuit boards can be supplied in standard or coated form for environments with airborne contaminants.

The housing stands 386 mm high, 190 mm wide, and 244 mm deep yet weighs only 13 kg, which helps reduce cabinet loading. Conductive-path design limits residual bus drop to 6 V, supporting power sharing among stacked drives. A dual-channel STO function interrupts gate signals with leakage not exceeding 100 mA, providing fail-safe torque removal without external contactors. Fan-regulated airflow keeps operational noise below 62 dB(A). The compact enclosure also supports dense cabinet layouts where multiple servo axes are mounted close together.
