Product Description:

The S7480C-PNF2-S3 is a Kollmorgen drive from the S700 Servo Drives series. It conditions three-phase mains power, generates controlled motor currents, and supervises feedback so that automated machinery can follow commanded torque, speed, or position profiles with tight accuracy. By integrating safety logic and thermal management, the unit functions as the main power stage for servomotors on packaging lines, material-handling gantries, and other motion axes that demand continuous regulation. This arrangement supports stable motion control in systems that require repeatable response during starting, running, and stopping.

Rated to accept line voltages from 208 to 480 V, the drive can draw up to 35 kVA of input power while supplying a continuous phase current of 48 Arms and momentary peaks of 96 Arms. An 8 kHz switching frequency shapes these currents and limits residual switching losses, and a 60 A AC supply fuse protects upstream conductors. With a residual voltage drop of 6 V, the drive maintains motor torque during bus sag events. Thermal dissipation is 24 W when the power stage is disabled, and cold-plate operation keeps the heat sink below 75 °C. Auxiliary fans switch on at 65 °C internally and 80 °C at the heat sink, while full-load thermal resistance remains 0.051 K/W when the mounting surface meets 25 µm/100 mm flatness.

Waste heat is removed through the base without forced airflow, and a fan-controller expansion card is included for added convection control when the installation calls for it. At a distance of one meter, sound output does not exceed 62 dB(A). The unit spans 190 mm in width and weighs 10.4 kg, which helps with cabinet spacing and mounting support. Dual-channel STO supports safety-related stop functions, and the aluminum housing helps maintain a stable thermal path to the mounting surface.
