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)
