Product Description:

The S7480A-PNF2-F2 belongs to the S700 Servo Drives series from Kollmorgen and functions as an AC servo drive that supplies regulated power to matched servomotors in multi-axis automation. By converting the three-phase line supply into controlled output waveforms, it provides velocity and torque regulation for positioning tasks, material handling, and coordinated motion lines. Its control stage helps the connected motor maintain stable motion when load conditions change during axis movement.

This drive accepts a line range of 208–480 V and is rated to handle 35 kVA of input power while delivering a continuous output of 48 Arms. For brief acceleration or shock loads, it can supply up to 96 Arms, and the internal IGBT bridge switches at an 8 kHz output-stage frequency so current ripple remains low; the output current form factor is 1.01. A residual DC-link drop of 6 V helps maintain motor voltage when the line sags, and dual-channel STO is provided for immediate torque removal without opening the main contactor. When the drive is disabled, it dissipates only 24 W, whereas normal operation generates substantial heat that must be removed with the coldplate option and a dedicated fan-controller expansion card. Mounting surfaces must stay within 25 µm per 100 mm to avoid mechanical stress on the power modules.

The coldplate assembly weighs 10.4 kg and attaches to panels that are at least 190 mm wide. The overall housing measures 386 mm high without connectors and carries an IP20 protection rating suited for enclosed cabinets. Acoustic emission does not exceed 62 dB(A) at full load, which helps limit noise in the surrounding work area. Coated PCBs resist conductive dust, and total thermal loss at 400 V is 635 W, so cabinet airflow must be sized accordingly to keep semiconductor junctions within limits while the forced-air path is guided by the optional fan controller.
