Product Description:
The S77202-NANA-F2 servo drive is produced by Kollmorgen within the S700 Servo Drives series. Designed for cabinet installation, the unit conditions three-phase power and provides closed-loop current, velocity, and position regulation for synchronous or induction servomotors used in material handling, packaging, and processing cells. The drive forms the interface between the incoming AC supply and the motor windings, coordinating torque commands from a motion controller and supporting the safety functions used in modern industrial automation.
The drive accepts a nominal supply of 208 to 480 V, and its power section is rated at 50 kVA, supporting continuous motor current up to 72 Arms. For rapid accelerations, the output can reach 140 A rms for five seconds before returning to its thermal limit. Pulse-width modulation operates at 8 kHz, and the inverter is permitted to switch 30 times per hour to reduce stress on the IGBTs. A residual DC-link drop of 6 V supports predictable braking, and a 10 Ω external resistor can be connected for additional energy dissipation. There is no expansion card slot, while EtherCAT and CANopen masters are integrated into the base unit, and standard PCBs are used for stable signal handling.
An internal fan activates at 65 °C, and together with an idle dissipation of 24 W, it helps keep the power section within its operating range while the drive can absorb 8 kW of continuous brake power into the DC link. The safety architecture includes dual-channel STO, allowing immediate torque removal when requested by the control system. The housing weighs 13 kg and measures 386 mm in height, 190 mm in width, and 244 mm in depth, which suits cabinet layouts that need a compact but high-output drive. Airborne noise remains below 68 dB(A), helping the unit fit enclosed machine installations where controlled heat removal and consistent motion response are important.
