Product Description:

The S7480A-FBF2-NA is a digital servo drive manufactured by Kollmorgen as part of the S700 Servo Drives series. Installed between a motion controller and a brushless servo motor, the unit regulates current, velocity, and position so automated axes follow commanded profiles accurately in material handling, packaging, and general machinery. This allows the connected axis to accelerate, hold speed, and stop with repeatable control during synchronized machine cycles. Its control section is suited to closed-loop servo applications where the drive must respond quickly to changing load demands. EtherCAT and CANopen interfaces are included on the base board, and an expansion card acts as a fan controller for auxiliary blowers.

The drive operates from a three-phase input supply of 208 to 480 V, with its IGBT bridge switching at 8 kHz. It can supply a continuous motor phase current of 48 Arms and draw up to 35 kVA from the supply. That input range allows the drive to work with common industrial power systems. The minimum motor inductance is 0.88 mH at the 480 V limit so that current ripple stays within controller assumptions. The residual voltage drop across the power stage is 6 V, leaving most of the bus voltage available for motor back EMF generation. Thermal energy is extracted through a coldplate base, which supports direct mounting to a shared chilled plate.

The drive has a dv/dt capability of 4.8 kV/µs, supporting fast vector transitions while observing motor insulation limits. For safety-related stops, it provides Dual channel STO, which can be used in Category 3 or 4 circuits without external contactors. The enclosure is 386 mm tall, 244 mm deep, and 190 mm wide, while the unit weighs 10.4 kg. The narrow housing helps conserve panel width in multi-axis cabinets. The coated PCB finish helps resist condensation in humid process areas. The onboard fan-controller card can supervise external blowers without additional PLC logic.
