Product Description:

The SM 6.5/30-GC inverter module is produced by Bosch Rexroth Indramat within the SM AC Inverters series. It serves as the power stage that converts a stabilized DC link into a variable-frequency, variable-voltage three-phase output for driving motors in automated production lines, conveyor sections, or positioning axes. By fitting into a modular rack system, the unit allows axis count to be scaled while maintaining a common bus architecture for energy sharing and coordinated control.

The power electronics inside switch at 5 kHz. This pulse-width modulation rate shapes output waveform resolution and affects acoustic noise. Under natural convection, the module supplies a continuous current of 6.5 A, while forced ventilation raises the continuous limit to 15 A, providing additional thermal margin when cabinet airflow is available. For rapid acceleration or transient overloads, it can deliver a peak of 30 A for five seconds without exceeding its semiconductor stress limits. The DC bus feeding the stage is nominally 325 V DC, so the inverter can generate line-to-line voltages suited to standard 230 V class motors. Command and diagnostic data move over a CAN interface, allowing integration with distributed motion controllers. The housing carries an IP20 rating that blocks direct access to live parts.

A climate class of 3K3 means the module is intended for clean, temperate industrial halls without condensation or conductive dust. Heat produced by the switching devices amounts to 13 W, so cabinet cooling requirements remain low. The aluminum frame measures 262.1 mm in height, 60.36 mm in width, and 232.19 mm in depth, filling one rack slot and occupying 12 TE across the backplane. With a mass of 2.4 kg, the module can be inserted or removed without additional lifting aids. The single-slot design also preserves space for future axis expansion.
