Product Description:

The S77202-SNF2-S3 is a Kollmorgen servo drive positioned within the S700 Servo Drives series. As an AC-powered amplifier, it interfaces between a motion controller and a three-phase motor to regulate torque, speed, and position in automated machinery. By converting commanded velocity profiles into accurate motor current, the unit supports applications such as packaging gantries, electronic assembly stations, and indexing tables where deterministic motion is essential.

During continuous operation, the drive supplies a nominal output current of 72 Arms, while momentary overloads can reach 140 Arms for brief acceleration bursts. Its input section accepts line voltages from 208 to 480 V and uses an 8 kHz output stage frequency to reduce current ripple. Peak current can be sustained for 5 s before thermal foldback limits engage. The housing has an IP20 protection rating, which means it is finger-safe but intended for cabinet mounting. For dynamic loads, the rated 50 kVA input power provides headroom, and SynqNet fieldbus connectivity supports deterministic network control alongside dual-loop feedback. The internal design uses the Standard PCBs option, which keeps component layouts consistent across the platform.

Mechanical integration is supported by a depth of 244 mm, along with a width of 190 mm and a height of 386 mm, allowing side-by-side stacking on 300 mm deep panels. Cooling is forced by the F2 fan controller, and a matching fan unit at the expansion card slot helps maintain airflow when neighboring drives raise the ambient temperature. A dual-channel STO circuit provides redundant torque shutoff paths without mechanical contactors. Start-stop duty is limited to 30 cycles per hour to reduce inrush stress. The aluminum chassis weighs 13 kg, which keeps panel mass manageable.
