Product Description:
The S7480F-PNF2-NA is a servo drive manufactured by Kollmorgen and supplied within the S700 Servo Drives series. It is intended for closed-loop motion control of brushless AC motors, where it regulates speed, torque, and position through high-speed field-oriented algorithms. By combining power electronics with integrated Profinet connectivity, the drive links actuators to PLC-based systems for coordinated multi-axis tasks on packaging lines, material-handling gantries, and process equipment. This arrangement supports synchronized motion where several axes must respond to the same control system without separate network hardware.
The unit is built into a steel enclosure rated at IP20, suitable for mounting inside a control cabinet. It delivers a continuous motor phase current of 48 Arms and can reach 96 Arms during acceleration or shock loads. Continuous brake power is 8 kW, and regenerated energy is dissipated through an external 15 ohm brake resistor connected to the DC link during deceleration. A switching frequency of 8 kHz balances current ripple with thermal stress on the IGBTs, while cooling airflow is supervised by an expansion card that functions as a dedicated fan controller. Standard and coated PCBs are available, and the coated option helps protect conductive traces from moisture. The housing measures 505 mm high, 285 mm deep, and 190 mm wide, and the 13 kg mass supports straightforward panel mounting.
The power stage accepts a three-phase supply from 208–480 V and is rated for 35 kVA of apparent input power, making it suitable for a wide range of industrial power systems. Network communication is handled through the Slot 1 PROFINET interface, which supports cyclic data exchange at 100 MBit/s for command, status, and diagnostic traffic between the drive and the controller. Functional safety is implemented through a dual-channel STO circuit that removes gate-drive energy in less than 10 ms, allowing compliance with EN 61800-5-2 stop requirements without external contactors. This safety function helps the drive transition quickly to a no-torque state when the stop input is activated.
