SM 1.5/3-TCT by Bosch Rexroth Indramat

The SM 1.5/3-TCT from Bosch Rexroth Indramat fulfills demanding industrial automation requirements as a high-performance member of the SM AC Inverters series. This rack-mountable Servo Module delivers a Rated Current of 1.5 A continuous and a Peak Current of 3 A, operating on a 560 V DC link voltage nominal (460 V nominal, up to 700 V maximum). Constructed with robust Transistor construction, the module weighs approximately 0.8 kg and supports both vertical and horizontal installation via integrated flange mounts. Its compact metallic casing features ventilation slots, providing EMI shielding and a compact footprint for space-constrained drive cabinets.

Technical excellence is evident through a broad range of integrated specifications. The unit employs Forced ventilation with an axial blower to maintain optimal thermal dissipation, complemented by a passive heatsink that obviates the need for active cooling elements. Its Protection Standard IP00 rating, per DIN 40050 and IEC 144, ensures safe operation in controlled indoor environments, while the Humidity Class F (DIN 40040 compliant) construction sustains performance in varying ambient moisture conditions. Diagnostic features include LED Indicators for fault conditions, enabling rapid troubleshooting. The drive module sustains reliable operation between 0 °C to 55 °C and up to 1000 m AMSL, with a Current Reduction of 1.2% per °K above 45 °C ambient to protect internal components under elevated temperatures.

Operational benefits stem from dependable performance in precise motion control scenarios. The integrated DB9 connector facilitates encoder or serial communication interfaces, while screw-type terminal blocks secure I/O and signal wiring against vibration and mechanical stress. With a Speed Regulation Range greater than 1:10,000, this drive module delivers fine resolution in velocity control, ensuring smooth acceleration and deceleration profiles. Internal capacitor discharge to <50 V within five minutes enhances safety during maintenance, and the module’s Power Loss of 30 W maximum reduces energy waste and heat generation. These features collectively enable reliable, long-term operation in single-axis automation tasks without unplanned downtime.

Integration into complex automation systems is straightforward thanks to the module’s universal DC link compatibility and standardized form factor. The Module Type: Servo Module design seamlessly interfaces with external DC link supplies and central control units, supporting interoperability across drive trains. Its minimal Weight and compact dimensions allow easy retrofitting into existing cabinets, while built-in EMI shielding and robust construction simplify compliance with industrial electrical standards. Ideal for robotics, packaging machinery, and general motion control applications, the SM 1.5/3-TCT provides a versatile, high-precision solution for engineers seeking a reliable inverter in the SM series.
