6SE9213-6BA40 is Siemens MICROMASTER 3 (MM75) compact variable frequency drive, rated power 0.75kW, single-phase AC208~240V input, three-phase motor output, equipped with integrated Class A EMC filter. It adopts V/F control mode to adjust motor speed and torque, widely applied on conveyor belts, fans, pumps and small automated machinery. It is an end-of-life spare part for legacy Siemens MICROMASTER3 variable speed control systems.

This wall-mounted inverter has IP20 protection class and is installed inside control cabinets. Rated output current reaches 3.9A, supporting 150% overload for 60 seconds under constant torque load. Output frequency range is 0~400Hz. Front panel integrated keypad and digital display support local parameter setting, jog operation and fault code reading. Standard analog and digital I/O terminals accept external PLC control signals, and serial interface is available for communication connection. Compact dimension 175 ×73 ×141mm fits limited cabinet space.

Multiple LED status indicators display power, running state and fault alarms for rapid on-site troubleshooting. Built-in protection functions include overcurrent, overload, overvoltage, undervoltage, overheat and motor stall protection to prevent equipment damage under abnormal load. The operating temperature range is 0~50℃, suitable for continuous operation in general industrial workshop environments. Parameter backup and commissioning can be realized via operator panel.

6SE9213-6BA40 is obsolete Siemens inverter spare part. Many legacy production machines still use MICROMASTER3 drive platforms. When the original inverter fails, replacement with identical 6SE9213-6BA40 can reuse mounting holes, power and motor cables as well as saved parameter settings. Technicians install the inverter, set motor parameters and test run and speed regulation functions, so motor variable speed control system resumes operation and reduces production downtime.

Before shipment, every 6SE9213-6BA40 undergoes comprehensive functional inspection including power-on self-test, output waveform detection, I/O terminal test and insulation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter configuration and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, 6SE9213-6BA40 is reliable spare VFD for legacy Siemens MICROMASTER3 drive systems. It restores AC motor variable speed regulation, maintains equipment operation stability, extends service life of automation assets and avoids whole machine renovation.
