Product Description:
The S7480C-SEF2-S4 is a digital servo drive from Kollmorgen in the S700 Servo Drives series. It converts incoming three-phase AC power into regulated output for a permanent-magnet servo motor, allowing closed-loop control of speed and position in packaging lines, pick-and-place robots, and material handling axes. Acting as the power stage between a motion controller and the motor, it manages acceleration, deceleration, and stall limits while returning status information to the automation network. This arrangement helps the axis respond predictably during repeated starts, stops, and direction changes.
The drive accepts mains supplies from 208 to 480 V, so it can be connected to both low-voltage and standard industrial distribution systems. Its continuous output capacity is 48 Arms, which provides substantial phase current for medium-frame servo motors during steady operation. Heat is removed through a cold plate base, so the chassis can transfer losses into a cooled mounting surface instead of relying only on internal airflow. Functional safety is implemented with dual-channel STO, which disables torque production through two independent shutdown paths. An optional fan controller expansion card can switch external blowers according to inverter temperature, which is useful when the surrounding cabinet includes other heat-producing equipment.
In multi-axis machines, the drive uses a command structure that fits coordinated motion systems and supports consistent behavior across several servo axes. Built-in safety diagnostics verify that the power stage is isolated before motion is allowed to resume, which reduces the need for separate external checking circuits. Cable sizes and protective devices still need to match the electrical load of the connected axis, and the external heat sink must be sized to carry away the thermal losses produced during continuous duty. Because cooling is transferred into the mounting surface, cabinet air can remain available for contactors, controllers, and other nearby devices that still depend on airflow.
