Product Description:

The S7480A-PNF2-S4 is a servo drive manufactured by Kollmorgen within the S700 Servo Drives series. Classified under the product type of an S700 servo drive, it is installed between the motion controller and the motor to regulate phase voltage, speed, and position in automated machinery. Communication is achieved through the integrated PROFINET fieldbus interface, allowing cyclic data exchange with PLCs. The drive body is prepared for cabinet mounting and employs a controlled fan assembly managed by a dedicated expansion card to maintain airflow across its internal power electronics.

Electrically, the drive is specified for a three-phase supply of 208 to 480 V, delivering up to 48 Arms of continuous output to the motor windings. The internal converter switches at 8 kHz, a frequency that balances dynamic response with manageable electromagnetic emissions. Under rated conditions, the unit can process 35 kVA of apparent input power, and its conduction path has a residual voltage drop of 6 V from the DC bus to the motor terminals. Disabled thermal loss is limited to 24 W, reducing standby cabinet heating, while an output current form factor of 1.01 indicates that the waveform remains nearly sinusoidal and helps minimize motor heating from harmonic content.

From a mechanical and safety perspective, the S7480A-PNF2-S4 attaches to a chilled mounting plate that forms the cold-plate cooling path, and the same option package provides coated PCBs for enhanced moisture resistance. Overall height without connectors is 386 mm, width is 190 mm, and the cold-plate version weighs 10.4 kg, facilitating installation in medium-sized control enclosures. Acoustic output does not exceed 62 dB(A) at full load, helping reduce noise in the surrounding area. Functional safety is addressed by a dual-channel STO circuit that removes drive energy in milliseconds, and the thermal design supports stable operation during normal use.
