Product Description:

The S7480C-SNF2-S3 belongs to the S700 Servo Drives series produced by Kollmorgen. This servo drive forms the interface between the plant power bus and a synchronous servomotor, delivering controlled current and voltage so that position loops executed by a motion controller translate into repeatable mechanical motion. Dual-channel STO is integrated for functional safety, while three rear slots—SynqNet in slot 1, a fan-control board in slot 2, and an S1-2 safety card in slot 3—provide network, cooling, and safe-torque-off expansion without external enclosures.

The drive supplies a continuous phase current of 48 Arms, and it can surge to 96 Arms for short acceleration peaks without leaving its thermal operating range. Line power up to 35 kVA is accepted across a mains voltage range of 208–480 V, allowing the same model to be used on both mid-voltage and high-voltage factory feeders. Internal semiconductor design limits residual DC drop to 6 V, which helps the connected motor develop rated torque under weak-grid conditions. In safety-related shutdowns, the power stage reaches its disabled state within 4 ms, aligning with Category 3 stop requirements. The housing measures 190 mm wide, 285 mm deep with connectors, and 505 mm high, which keeps the unit within standard 600 mm cabinet frames while still allowing clearance for cable bends and airflow.

A cold-plate base extracts heat directly to the panel wall, so only 635 W of convection heat must be removed at 400 Vac. The aluminum plate and power electronics bring the assembly mass to 10.4 kg, which supports stable cabinet mounting and helps damp vibration. Acoustic output does not exceed 62 dB(A) when the auxiliary fan controller cycles at the specified 30 switch-on events per hour, helping keep enclosure noise within typical production-floor limits while maintaining normal component temperature.
