Product Description:

The S77202-FBF2-S4 servo amplifier is produced by Kollmorgen within the S700 Servo Drives series. This unit is an S700 servo drive that converts three-phase AC from the mains into controlled motor currents so a motion controller can execute precise speed and position loops. In automated packaging, robotics, or material-handling stations, the drive supplies dynamic torque while also monitoring feedback devices and safety channels to keep axes synchronized with plant commands.

Its continuous output capacity reaches 72 Arms, giving sufficient phase current for medium-inertia servomotors operating under constant load. For acceleration bursts, the power stage can deliver up to 140 ARMS per phase for 5 s, enabling machinery to overcome friction and startup torque without oversizing the entire system. A wide input window of 208 to 480 V allows the same model to run on North American or European distribution networks. When the axis is idle, the control section dissipates only 24 W, which helps limit cabinet heat. An integrated CE line filter attenuates conducted emissions, so additional external filtering is rarely required.

Overcurrent protection is handled by an 80 A AC supply fuse that opens the circuit if internal faults drive input current above safe limits. The drive chassis measures 244 mm deep, 190 mm wide, and 386 mm high, allowing dense stacking inside machine panels, and it carries an IP20 protection rating, so it must be installed in a shielded enclosure. At 13 kg, the unit remains manageable for cabinet installation and service access. A plug-in fan-controller expansion card governs airflow across the heat sink, dual-channel STO provides safe torque off, and the standard PCB option together with a three-phase AC input completes the hardware package used for the S700 platform.
