General connection examples

WARNING

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.

Note

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!

Connection types

The Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.

Note

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)!

Documentation for stepper motors from Beckhoff

These two examples show the connection of the bipolar Beckhoff motors AS1010, AS1020, AS1030, AS1050 or AS1060. Further information on stepper motors from Beckhoff can be found in the associated documentation available for download from our website at http://www.beckhoff.com.

Bipolar control of a unipolar motor

Only one half of each winding is controlled.
