Product Description:

The S74802-PNF2-PA belongs to the S700 Servo Drives series produced by Kollmorgen. This unit is a servo drive intended to regulate torque, speed, and position of synchronous or induction servomotors in automated machinery. The product type is listed as an S700 Servo Drive, and by converting incoming three-phase power into a controlled output it provides the closed-loop actuation needed for precise motion sequences on packaging lines, gantries, and processing stations.

The drive accepts a rated input power of 35 kVA, operates within a permissible mains range of 208 to 480 V, and delivers a continuous phase current of 48 Arms to the connected motor. For short accelerations, the inverter can source a peak output of 96 Arms, and its IGBT bridge commutates at 8 kHz to minimize current ripple. Command signals enter through an analog ±10 V interface, while dual RJ45 Profinet ports form the real-time fieldbus backbone. A fan controller expansion card manages airflow across the standard PCBs, helping the 13 kg enclosure dissipate heat generated at full load. Physical installation requires 190 mm of width, 386 mm of height, and 244 mm of depth, dimensions that suit multi-axis cabinets fed from a common three-phase AC bus.

Operation is synchronized with supply grids running at 50/60 Hz, and overload bursts are limited to 5 s to protect power devices. Functional safety is supported by a dual channel STO circuit that removes gate drive energy without mechanical contactors. The housing carries an IP20 rating, so it is intended for mounting inside a protected electrical panel where its standard PCBs remain free of conductive debris. Additional safeguards include temperature monitoring tied to the fan controller and compliance with the ±10 V analog range, supporting predictable behavior when paired with Kollmorgen motors over the Profinet link.
