Product Description:

The S7480F-2CF2-S4 servo drive is manufactured by Kollmorgen within the S700 Servo Drives series. It serves as the power conversion and control element between a three-phase 208–480 V supply and brushless servo motors used in positioning, packaging, and material-handling machinery. By modulating current and voltage, the unit delivers precise torque and speed commands required for closed-loop industrial automation. This operating role lets the drive manage acceleration, deceleration, and steady-state speed while the connected feedback system allows the motor to follow commanded motion accurately. Its application range fits equipment where repeatable axis response is needed during frequent starts, stops, and directional changes.

It accepts a line voltage range of 208–480 V and operates with a rated phase current of 48 Arms, while transient demands can be met with a peak output of 96 Arms. The internal IGBT bridge switches at an output stage frequency of 8 kHz, which helps limit motor ripple and audible noise during operation. Dual-channel safe torque off protection, shown as Dual channel STO, removes torque-producing power at the hardware level when an emergency stop is triggered. The permitted 30 switch cycles per hour help prevent thermal overstress of the power section, and the residual voltage drop is 6 V to support low-speed motor control. A dedicated fan-controller expansion card regulates airflow across the heat sink so internal temperatures remain controlled during continuous load periods.

In continuous service, the drive draws up to 35 kVA from the mains and releases approximately 635 W of heat at 400 V, so enclosure ventilation should be sized for that load. Mechanical dimensions without connectors measure 190 mm in width, 244 mm in depth, and 386 mm in height, which helps support dense cabinet layouts in control cabinets with limited depth. Even with its cooling fans, the unit’s acoustic output remains below 62 dB(A), which helps keep nearby work areas quieter during operation. The aluminum chassis weighs 13 kg, which helps reduce handling load during panel mounting and makes the drive easier to position inside compact enclosures.
