AKT2G-SM-L15 General Connection Examples


  • Risk of injury through electric shock and damage to the device!

    Bring the Bus Terminal system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals.

Connection types

The AKT2G-SM-L15 Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.


  • Fuse protection of the supply voltage

    The electrical protection of the load voltage must be selected in such a way that the maximum flowing current is limited to 3 times the rated current (max. 1 second)!
