Product Description:

The S7480A-PNF2-S3 is a servo drive produced by Kollmorgen within the S700 Servo Drives series. It is designed to modulate voltage and current for precise control of servo motors. This supports coordinated motion tasks such as positioning, tensioning, and synchronized axis movement in automated machinery and production lines.

This model accepts a three-phase supply between 208–480 V, giving it compatibility with common factory power grids. A continuous output capability of 48 Arms supports medium-to-high torque motors without derating. Thermal energy is extracted through a coldplate interface, so the unit must be fastened to a heat-sinking surface rather than relying on internal airflow. When the motor is idle, the drive dissipates only 24 W, reducing cabinet heat load during standby periods. Integrated safety technology identified as dual-channel STO removes drive power at the gate level to meet functional safety stop requirements. A residual DC-bus drop of 6 V remains available for low-level control electronics, while a 100BaseTX Ethernet port allows real-time parameter access. The optional fan-controller expansion card can command auxiliary blowers when the application requires forced convection.

A power requirement of 35 kVA sets the maximum upstream breaker and cable gauge for this drive. The housing is 505 mm high, 190 mm wide, and 285 mm deep, which helps fit the unit into standard cabinet layouts. The installation weight is 10.4 kg, which helps reduce lifting effort during mounting. At full load, the unit produces 62 dB(A) of acoustic noise, a value that can be used when planning enclosure sound control. Conformal coating on all PCBs shields sensitive traces from humidity and conductive dust, and the coldplate and coated PCB option confirms that this protection is included.
