Product Description:
The SM 18/60-GC is an AC inverter assembled by Bosch Rexroth Indramat as part of the SM AC Inverters series. Within an automation cell, this unit converts fixed mains power into a variable-frequency, variable-voltage output so drives can modulate motor speed in real time. It slots directly into a modular rack and interfaces with the plant controller to execute torque, speed, and position commands for conveyors, pumps, or processing lines.
The drive’s switching transistors operate at a carrier frequency of 5 kHz, a rate that affects output waveform resolution and audible noise. When fan cooling is applied, it can deliver a continuous output current of 18 A, enabling sustained operation of medium-frame induction motors. For short acceleration bursts, the inverter tolerates a peak of 60 A for five seconds, giving extra torque during machine startup. A stabilized DC link of 325 V DC is maintained by the rectifier stage, and this voltage supplies the internal IGBTs while setting the maximum motor voltage. The housing carries an enclosure rating of IP 20, so installation must occur inside a cabinet where accidental contact with live parts is prevented.
Additional parameters describe how the module fits into control cabinets and the surrounding environment. Thermal dissipation is limited to 13 W, allowing dense rack layouts without intensive cooling hardware. Reliable operation up to 1000 m above sea level is permitted, and the device is specified for climate class 3K3, meaning it can handle moderate humidity and temperature fluctuations common on factory floors. Field communication occurs over a CAN interface, while two back-plane slots are reserved for the unit to support orderly rack integration. A mass of 3.5 kg keeps handling manageable during panel assembly and minimizes mechanical load on card guides.
