Product Description:

The S74802-SNF2-NA is a modular servo drive manufactured by Kollmorgen and assigned to the S700 Servo Drives series. It forms the regulated power interface between a three-phase supply and a brushless servo motor, shaping current and monitoring feedback for closed-loop motion in packaging machines, material-handling gantries, and other automated equipment. Native fieldbus slots allow direct connection to machine controllers so that position, velocity, or torque commands reach the motor without external converters.

The drive sustains a continuous output of 48 Arms, which is the current it can deliver indefinitely without surpassing its thermal limit. Transient demands are covered by a peak capability of 96 Arms, enabling fast acceleration of high-inertia loads. Mains compatibility spans 208–480 V AC, and the internal rectifier charges the DC bus up to 900 VDC for efficient energy transfer to the inverter stage. Line-side loading tops out at 35 kVA, which is used when sizing circuit protection and cabling. Motors connected to the unit must have at least 0.88 mH of phase inductance so that switching ripple remains within design limits. The power section contributes only a 6 V residual voltage drop, helping maintain speed under heavy load. With a width of 190 mm and a mass of 13 kg, the housing fits into multi-axis cabinets while leaving space for additional automation components.

When idle, the electronics dissipate just 24 W, which reduces standby power draw and cabinet heating. Acoustic output is limited to 62 dB(A), aided by a temperature-controlled fan driven by the integrated fan-controller expansion card. Safety is addressed through a dual-channel STO circuit that removes drive power without affecting fieldbus communication. EtherCAT and CANopen are available on the controller board for standard motion profiles, while Slot 1 accepts a SynqNet card with two RJ45 ports for distributed synchronization. Standard PCBs are used throughout to simplify service procedures.
