Product Description:

The S74802-EIF2-S3 servo drive is produced by Kollmorgen as part of the S700 Servo Drives series. Designed for closed-loop control of rotary synchronous motors on factory lines, it converts three-phase mains power into regulated current and maintains precise velocity and torque feedback for positioning tables, pick-and-place axes, and similar automation tasks. The unit belongs to the S700 Servo Drive product type, giving a matched controller for high-performance motion while retaining footprint compatibility with other modules in the series.

Within an S700 rack, the drive exchanges setpoint data every 4 ms, allowing high-speed interpolation between axes. Its microcontroller updates output transistors in 10 ms, so commanded torque steps appear at the motor terminals without noticeable lag. A carrier frequency of 8 kHz minimizes current ripple and audible noise, and the power stage can continuously deliver 48 Arms to a connected rotary synchronous motor supplied from mains in the 208 to 480 V range. Fourteen digital inputs accept 24 V logic, eight digital outputs return status at 24 V/500 mA, and a 24 V / 7 mA control input provides enable signaling. Dual-channel STO circuitry removes drive energy for safe stop functions, while an optional fan-controller expansion card supervises thermal accessories. External protection is implemented with a 4 AT fuse to isolate faults, and the unit uses standard PCBs for general industrial environments.

The housing measures 190 mm in width, 244 mm in depth, and 386 mm in height, enabling direct panel mounting beside breakers and contactors. Internal airflow starts when the heat sink reaches 65 °C, and the optional fan controller can regulate auxiliary blowers for extended duty. The drive draws up to 35 kVA under rated load, while its standard PCB construction supports operation in clean electrical cabinets.
