Product Description

The SERVOSTAR 446M-C is a discontinued digital servo drive belonging to Kollmorgen SERVOSTAR 400 series (Danaher Motion). This unit is designed for 230 V AC single‑phase or three‑phase power supply, delivering 6 A continuous RMS output current with 12 A short‑time peak overload capacity.

The suffix‑C stands for integrated on‑board CANopen fieldbus interface, alongside standard RS232 service port. An expansion slot is available for optional fieldbus add‑on cards including PROFIBUS‑DP, SERCOS or DeviceNet. It supports resolver, TTL/HTL incremental, EnDat, Hiperface, Sin‑Cos and hall sensor feedback types. Control functions cover torque, speed, position operation, electronic gearing and cam profiling.

Equipped with analog and digital I/O terminals for machine logic connection, it is widely used as spare replacement component for old packaging machines, handling systems and custom automation equipment. Original manufacturing has been terminated; available stock consists of tested used or refurbished surplus units.
