AKT2G-SM-L50 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.
-
-
Connect the motor strands correctly!
Connect the windings of a motor strand only to the terminal points of the same output driver of the stepper motor terminal, e.g.:
- one motor strand to terminal points A1 and A2,
- the other motor strand to terminal points B1 and B2.
Connecting a motor strand to the terminal points of different output drivers (e.g. to A1 and B1) can lead to destruction of the output drivers of stepper motor terminal!

-
Use a brake chopper terminal (Global search and replace: AKT2G-BRC-000-000) for short deceleration ramps!
Very short deceleration ramps may lead to temporarily increased feedback. In this case the terminal would report an error. In order to avoid this, a brake chopper terminal AKT2G-BRC-000-000 should be connected in parallel to the power supply for the motor so that any energy being fed back is absorbed.

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)!
Connection types
The AKT2G-SM-L50 Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.

Encoder
Connecting an encoder (24 V)
