Product Description:

The S7480C-DNF2-S4 is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. It regulates torque, speed, and position for synchronous and induction motors used in automated machinery, packaging lines, and material-handling cells. By converting three-phase mains power into controlled output to the motor, the unit serves as the intermediary between motion commands from a controller and the mechanical work carried out by the axis. This arrangement lets the drive respond quickly to changing load and motion demands during operation.

The drive accepts a line supply of 208–480 V and draws a maximum of 35 kVA under rated conditions. It can deliver a continuous phase current of 48 Arms and withstand transients up to 96 Arms during acceleration or rapid load changes. Command signals are processed through an analog input window of ±10 V, while digital control lines load the opto-isolated inputs at 15 mA and source peripheral devices with 100 mA from the outputs. A residual voltage drop of 6 V appears between the DC bus and motor terminals, which is useful when calculating thermal margins in the motor windings. The drive uses DeviceNet for fieldbus communication, allowing node addressing and cyclic data exchange with higher-level PLCs. When the power stage is inhibited, internal losses fall to 24 W, reducing cabinet heat load during standby.

Cabinet layout benefits from a depth of 244 mm, a height of 386 mm, and a width of 190 mm, all measured without plug-in connectors. Forced convection is provided by a controlled fan that is monitored by a dedicated fan-controller expansion card, and a cold plate option enables conduction cooling when airflow is restricted. Acoustic output does not exceed 62 dB(A) at full load. The drive includes dual-channel STO, so motion can be safely inhibited without removing mains power.
