Product Description:

The S77202-EIF2-S3 is a Kollmorgen servo drive in the S700 Servo Drives series. It converts three-phase mains power into regulated motor output for coordinated axis control, so it can manage acceleration, deceleration, and holding functions during continuous machine operation. Integrated position-loop processing and fieldbus connectivity let the drive respond quickly to changing commands while maintaining stable torque delivery. This makes it suitable for packaging systems, palletizers, and multi-robot cells that require fast motion changes, repeatable positioning, and consistent control across several synchronized axes.

This drive operates directly from a three-phase supply of 208 to 480 V, allowing one unit to fit a wide range of industrial power systems. Under rated conditions, it delivers 72 Arms to the motor windings, and it can sustain overload demand for up to 5 s during short dynamic events such as acceleration or abrupt load changes. A built-in dual-channel STO function removes power from the output stage without the use of contactors, adding a direct safety measure at the drive level. Command logic is handled through a control input rated at 24 V / 7 mA, which keeps signal demand low, while status and interlock functions can be supplied at up to 24 V / 500 mA for external relays, lamps, or similar control devices.

The drive includes 14 additional digital inputs and 8 digital outputs, which support direct connection of switches, sensors, clamps, and other machine signals without depending on a separate I/O block for basic functions. Cooling is managed by a controlled fan, and fan operation is handled through an onboard expansion card so airflow is applied when internal heat load requires it. The housing measures 190 mm wide, 386 mm high, and 244 mm deep, which helps the unit fit into densely populated control cabinets alongside other power components and wiring channels. Its installation weight is 13 kg, giving the drive a solid form factor without making panel mounting unusually difficult for standard enclosure layouts.
