Product Description:

The S7480C-SEF2-S3 is a servo drive produced by Kollmorgen within the S700 Servo Drives series. This unit regulates three-phase servomotors in industrial automation cells, converting the incoming AC supply into controlled output current while coordinating position and velocity loops. The drive is supplied in a coldplate configuration, allowing direct mounting to a cooled surface for optimized heat removal, and it includes an integrated fan-controller expansion card for local blower management.

Electrical performance centers on the wide input range of 208 to 480 V, letting a single part number serve both low-line and high-line facilities. Under nominal conditions, the power section accepts 35 kVA and can deliver 48 Arms continuously, allowing high-torque motors to operate without pushing the inverter near its limit. Modulation occurs at 8 kHz, a switching frequency that balances motor acoustics with semiconductor dissipation, while the safety system provides dual-channel STO, removing power to the motor within the reaction time required for Category 3/4 architectures. A residual voltage drop of 6 V on the DC bus keeps the control electronics active during coastdown, and thermal loss in the disabled state is 24 W, reducing cabinet heat when the axis is idle.

Physical data help size enclosures for the drive. With connectors installed, the unit stands 505 mm tall, spans 190 mm in width, and projects 285 mm in depth. The coldplate itself weighs 10.4 kg, contributing to the overall mass and acting as the primary thermal interface. During motion, the inverter’s cooling fans keep workplace sound pressure at 62 dB(A), a value suited to plant floors with occupational noise limits. At a DC link of 400 V, the unit rejects 635 W through the baseplate, so a chilled plate or liquid-cooled panel is needed to keep the remaining electronics within the temperature limits of the fan-controller option card.
