Product Description:

The S77202-2CF2-PM is a servo drive built by Kollmorgen and placed in the S700 Servo Drives series. It functions as a power and control interface between a three-phase mains supply and synchronous or induction motors used in positioning, packaging, and material-handling cells. By modulating its output stage, the unit converts fixed-frequency line power into variable motor power so the automation controller can command speed, torque, and direction with millisecond precision. This operating role makes it suitable for coordinated axes that need repeatable starts, stops, and speed changes during automated cycles.

The drive is protected to IP20, so it must be installed inside an electrical cabinet where accidental contact and contamination are already limited. Its mains terminals accept line voltages from 208...480 V, allowing one hardware model to cover both 230 V and 460 V plant networks. This voltage range supports machine platforms that may be installed in facilities with different utility standards. Continuous motor current is limited to 72 Arms, while the power section supports a maximum apparent input of 50 kVA. The output stage switches at 8 kHz, which helps reduce audible noise and supports stable current control. For short acceleration bursts, the current regulator can supply up to 140 Arms, giving the axis additional torque during rapid speed changes.

Functional safety is handled through a built-in dual-channel STO circuit that removes motor energy within the required reaction time while maintaining encoder feedback integrity. This arrangement supports machine functions that need a controlled stop response without immediately interrupting feedback signals to the control system. During nominal cycling at 400 V, the power electronics release 1005 W as heat, so forced airflow from the optional fan controller card is recommended to keep heat-sink temperature within limits. The unit weighs 13 kg and measures 190 mm wide by 285 mm deep and 505 mm high with connectors. That size allows the drive to fit beside other S700 models on a common mounting plate without exceeding typical 600 mm cabinet depths.
