Product Description:

The S7480F-DNF2-S3 servo drive is manufactured by Kollmorgen as part of the S700 Servo Drives series. This S700 servo drive converts three-phase mains power into precisely regulated output currents for servo motors used on packaging, pick-and-place, and material-handling axes. By integrating torque, velocity, and position loops internally, it reduces cabinet wiring and supports precise motion control where repeatable axis response is required. The design suits medium-to-high power machines that need coordinated servo performance in industrial automation.

The drive handles a continuous input power of 35 kVA and accepts line voltages from 208 to 480 V, allowing direct connection to common industrial feeders. It provides a continuous motor phase current of 48 Arms and can supply 96 Arms for 5 seconds during acceleration peaks. The output current is switched at 8 kHz, which supports responsive control while limiting switching losses. A residual DC-bus voltage drop of 6 V helps reduce regenerative stress on upstream equipment. The dedicated fan-controller expansion card removes heat at these current levels, and the DeviceNet interface installed in slot 1 exchanges command and status data with the host PLC.

Functional safety is provided by a dual-channel STO circuit, which removes torque-producing power when the safety channel is activated. The S1-2 safety card adds motion interlock capability for the drive. Maximum acoustic output is limited to 62 dB(A), and the unit dissipates only 24 W at idle, which helps keep enclosure temperatures manageable. The housing measures 190 mm wide, 386 mm high, and 244 mm deep, and it weighs 13 kg for panel-mounted installation.
