Product Description:

The S77202-PNF2-S3 is manufactured by Kollmorgen and belongs to the S700 Servo Drives series. Acting as the intermediary between a three-phase mains supply and a matched servo motor, it regulates the power delivered to the axis during operation. It produces the commanded torque, speed, and position profiles required for automated packaging, material-handling, or assembly axes within industrial automation cells.

The drive accepts an input range of 208 to 480 V and delivers a continuous output of 72 Arms. When rapid acceleration is needed, it can produce 140 Arms for up to 5 seconds, which supports short overload periods during demanding motion changes. Pulse-width modulation at 8 kHz helps limit motor current ripple, while an onboard fan controller governs the cooling hardware. Two motion-network connections are provided through 2 x RJ45 PROFINET ports that operate on the 100BaseTX Ethernet standard, allowing daisy-chained installation without an external switch. Functional safety is built in, and the dual-channel STO circuit meets SIL CL3. The option set uses standard PCBs, and an expansion slot can hold a dedicated fan-controller card that activates heat-sink cooling above 80 °C or internal cooling above 65 °C.

The housing draws 50 A of apparent power at a rated load of 50 kVA and keeps acoustic output to 68 dB(A). Safety architecture is also supported by a performance rating of PLe, which suits machine designs that require a high safety category for drive shutdown. The enclosure measures 386 mm in height, 190 mm in width, and 244 mm in depth, with a shipping weight of 13 kg, so it fits within standard 600 mm deep control cabinets. High-temperature thresholds for the heat sink and internal air are monitored by the fan controller, allowing cooling response to follow internal operating conditions without manual adjustment.
