The MD3xxx series frequency inverters enable the operation of asynchronous motors in the MX-System and are part of a multi-axis system whose DC link is fed from a DC link module (MD6xxx). The motor is connected via a B17 hybrid connector, which includes brake control and temperature measurement of the motor windings via RTDs. ? In addition, the frequency inverters have integrated STO/SS1 functionality and TwinSAFE Logic.
