The SM AC Inverters series is a modular servo inverter platform within the Bosch Servodyn system, designed to operate with a separate supply module and one or more servo modules in a shared installation.
These units are intended for brushless Bosch servo motors and regulate torque and speed through a closed-loop control structure that combines rotor position recognition, tacho feedback, and current regulation. The series includes multiple current classes with defined continuous and peak current ratings, a 460 V DC link, forced-air cooling, and operation over a wide speed regulation range. The control section supports differential command inputs, enable and torque-reduction functions, motor feedback connections, ready contacts, analog monitoring outputs, and optional diagnostics for faults such as supply errors, module faults, commutation faults, tacho faults, excess temperature, blocked motor, and speed monitoring. Overall, the SM series is intended for modular servo drive systems that require coordinated supply architecture, adjustable control behavior, and fault-monitoring capability for industrial motion applications.
