Siemens 6SE9213-6CA40 | Siemens | MICROMASTER MM75/2 Frequency Converter

The 6SE9213-6CA40 is a MICROMASTER MM75/2 series frequency converter, engineered to provide reliable speed and torque control for AC induction motors in industrial applications. Designed for versatile power input compatibility, this unit operates on either single-phase or three-phase 208-240V AC supplies. It delivers a constant torque output of 0.75 kW and features a robust overload capability of 150% for 60 seconds, making it well-suited for applications requiring sustained performance under variable load conditions. Note that this specific model is currently designated as obsolete, with the 6SE6420-2UC17-5AA1 serving as its official successor.

Features

• Power Flexibility: Supports 1AC/3AC 208-240V input voltage for diverse industrial power configurations.
• Overload Capacity: Robust design allowing for 150% overload for up to 60 seconds.
• Compact Footprint: Dimensions of 175 x 73 x 141 mm (HxWxD) enable installation in space-constrained control panels.
• Environmental Protection: IP20 rated for protection against solid foreign objects, suitable for climate-controlled indoor environments.
• Operating Range: Reliable operation in ambient temperatures ranging from 0 to 50 degC.

Applications

• Small-scale industrial automation and assembly lines.
• Control of pumps, fans, and small conveyor systems.
• General-purpose motor speed regulation in HVAC or manufacturing equipment.
• Replacement or maintenance of legacy MICROMASTER drive systems.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the unit is installed vertically on a flat, non-combustible surface to promote proper airflow. Maintain minimum clearance requirements above and below the device.
• Wiring: Keep power lines separate from control signal cables to prevent electromagnetic interference.
• Ventilation: As the unit operates in temperatures up to 50 degC, ensure the control cabinet is properly ventilated to prevent thermal throttling.
• Successor Migration: When migrating to the successor model (6SE6420-2UC17-5AA1), verify terminal mapping and parameter settings, as the interface and programming structure may differ.
