Product Description:
The S7480A-2CF2-S4 is a servo drive produced by Kollmorgen within the S700 Servo Drives series. It conditions three-phase mains power and feeds precision motors with regulated voltage and current. This allows motion controllers to command accurate speed, torque, and position in automated packaging, assembly, and material-handling machines. The unit is intended for axis control where repeatable motor response is needed during synchronized machine motion and routine speed changes.
Nominal operation is based on a continuous output of 48 Arms, while short bursts can reach 96 Arms to cover acceleration peaks. The drive accepts mains supplies up to 35 kVA in a voltage range of 208 to 480 V, enabling installation on a wide range of industrial power systems. This input range allows the same drive platform to serve different facility standards without changing the basic control behavior. An output current form factor of 1.01 indicates nearly sinusoidal motor excitation, which helps limit additional I²R heating in the motor windings. Cleaner current delivery can also support smooth torque production at the motor shaft. The power stage introduces a residual 6 V drop, and with the thermal dissipation circuit disabled, only 24 W is lost as heat. Dual-channel STO inputs provide safe torque off without contactors, and a plug-in fan-controller card can supplement the standard cold-plate cooling arrangement when higher cabinet temperatures require forced air. Coated printed circuit boards inside the unit resist moisture and dust migration.
The drive is housed in a IP20 open-frame enclosure intended for mounting inside protected electrical cabinets. Because the enclosure is open frame, it is meant to be integrated into a cabinet rather than used as a standalone field-mounted unit. Its overall size of 505 × 190 × 285 mm helps with panel layout along the aluminum cold plate, and the assembly weight of 10.4 kg supports practical handling during installation. Maximum acoustic output is capped at 62 dB(A), which keeps operating noise within a typical industrial range. The cold-plate and coated PCB option combines conductive heat removal with added protection against airborne contamination.
