Product Description:

The S7480F-SEF2-S3 is a servo drive from Kollmorgen that belongs to the S700 Servo Drives series. It regulates torque, speed, and position for synchronous or induction servomotors in automated cells, packing lines, and material-handling axes. The housing measures 190 mm in width, 244 mm in depth, and 386 mm in height without connectors, so it fits a standard 300 mm cabinet frame without overhang. This layout helps the drive fit control cabinets where depth and side clearance must be managed carefully. It is intended for motion systems that need repeatable axis control, stable speed regulation, and coordinated response from the connected motor.

During continuous operation, the drive delivers 48 Arms of output current and supports peak bursts up to 96 Arms during rapid acceleration. It operates from a supply range of 208 to 480 V, and the output stage switches at 8 kHz to support motor control with manageable switching losses. The power stage is rated at 35 kVA, and the stated output current form factor of 1.01 indicates a waveform that remains close to sinusoidal. A residual 6 V drop appears across the output transistors, which is useful when estimating motor terminal voltage. The slot 1 interface uses SERCOS II for cyclic position data exchange with the controller. This current capacity allows the unit to support demanding motion profiles without immediately reaching its continuous limit during short bursts.

At 400 V, the heat sink must dissipate 635 W, and the integrated fan controller expansion card adjusts airflow to support that thermal load while keeping noise to 62 dB(A). The drive weighs 13 kg, which makes panel handling easier while still giving the unit a solid installed presence. Safety functions include a dual-channel STO circuit and an S1-2 safety card in slot 3 for encoder monitoring. In this version, the printed circuit boards are coated to help resist moisture. The coated boards help protect internal electronics in areas where airborne moisture may be present.
