Product Description:

The S7480A-NANA-PM is manufactured by Kollmorgen as part of the S700 Servo Drives series and functions as the power interface between a control system and a three-phase motor in industrial automation. By converting the incoming AC supply into controlled output waveforms, the drive supplies both continuous and transient currents needed for coordinated motion tasks while its dual-channel STO circuit provides a certified means of removing torque during safety events.

This model accepts mains within the range of 208...480 V and draws up to 35 kVA under rated load. Continuous motor excitation is supported by a phase current of 48 Arms, while acceleration and recovery cycles can reach a peak of 96 Arms for short intervals. The gate drivers manage switching so that the DC-link to phase transition rises at 4.8 kV/µs, keeping motor voltage distortion low when coupled with windings that have a minimum inductance of 0.88 mH at 480 V. Internal losses appear as heat equal to 685 W at full rating, and the residual voltage drop across the power stage remains limited to 6 V, helping maintain efficiency. EtherCAT and CANopen communications are provided on the base board, so no expansion card is required for real-time fieldbus control.

Mechanical integration is simplified by a footprint 190 mm wide, a depth of 285 mm with connectors, and an overall height of 505 mm. The coldplate cooling method transfers those 685 W into a machine frame or external chiller; this option is paired with coated PCBs to guard against moisture and conductive dust. The assembly weighs only 10.4 kg, easing cabinet mounting, and its maximum sound pressure level of 62 dB(A) keeps enclosure noise moderate. A voltage rise tolerant design, dual STO, and a residual thermal dissipation path confirm suitability for multi-axis cells where drives share a common coldplate and safety network.
