Product Description:

The S7480F-DNF2-S4 belongs to the Kollmorgen S700 Servo Drives series and serves as a three-phase AC drive for precision motion control in automated machinery. By converting the incoming mains voltage into programmable pulse patterns, it modulates torque and speed on matched servo motors for packaging stations, material-handling gantries, and robotics. It is intended for coordinated axes that require repeatable speed regulation and accurate positioning during changing load conditions.

This drive accepts a line supply of 208…480 V and is rated for 35 kVA input power, enabling operation on common industrial networks without an autotransformer. Under continuous load it supplies 48 Arms, and for dynamic peaks it can discharge up to 96 Arms, giving additional headroom for acceleration cycles. A carrier switching frequency of 8 kHz balances motor smoothness against device heating, while a residual voltage drop of 6 V helps maintain regulation accuracy when bus voltage sags occur. Dual-channel STO provides hardware-level torque removal, and a DeviceNet module occupies Slot 1 for real-time fieldbus integration. A removable fan-controller expansion card drives the internal blower, while standby thermal loss is limited to 24 W. The boards are available in standard and coated finishes, and the coated PCBs include a varnish layer that improves resistance to humidity and airborne contaminants.

With the shielding plate installed, the unit stands 505 mm high, spans 190 mm in width, and projects 285 mm in depth when connectors are fitted, allowing door-mount or back-panel layouts in 600 mm cabinets. The mass is 13 kg, which should be taken into account during panel mounting and support selection. Full-load switching produces 635 W of heat that must be removed by forced air, and acoustic output remains below 62 dB(A) so the drive can operate on a production floor without separate acoustic shielding. These dimensions also leave room for cable routing and airflow clearance in compact enclosures.
