Product Description:

The S7480A-2CF2-PA is a Kollmorgen drive from the S700 Servo Drives series. Designed for cabinet installation, the unit converts three-phase mains power into the controlled, pulse-width-modulated output required by modern servo motors. By managing phase current, monitoring feedback, and coordinating fieldbus commands, it forms the interface between a machine controller and the mechanical axis. The drive supports responsive torque, accurate velocity, and repeatable positioning in packaging, material handling, and process equipment.

The power section accepts line voltages from 208 to 480 V, enabling deployment on low or high line supplies without transformer adaptation. Under continuous operation, it can deliver 48 Arms to the motor phases before thermal derating begins. Command accuracy is supported by an analog input resistance of 20 kOhm, which minimizes loading on external sensors. The analog output stage resolves changes as small as 0.38 mV within a full-scale range of ±10 V, and real-time communication to the controller is handled through the integrated CANopen interface with a default speed of 500 kBaud.

Bus integrity is supported by the drive’s onboard termination of 120 Ohms, eliminating the need for an external resistor at the end of a short CAN segment. Thermal management is automated, and an embedded fan controller starts the ambient fan at 65 °C before energizing the heat sink blower when the case temperature reaches 75 °C; auxiliary airflow also cools the brake resistor at 45 W. Safety is provided through dual-channel STO, allowing the control system to remove torque-producing power through two independent circuits. The cold plate option and coated PCBs improve heat transfer and increase resistance to contamination and moisture when the unit is mounted directly on machine frames.
