WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminals system into a safe, de-energized state before starting mounting,
disassembly or wiring of the Bus Terminals.
Attention
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!
Attention
Use a buffer capacitor terminal (EL9570) for short deceleration ramps.
Very short deceleration ramps may lead to temporarily increased feedback. In this case the
terminal would report an error. To prevent this, one should connect a buffer capacitor ter-
minal (EL9570) with a suitable ballast resistance (e.g. 10 Ohm) in parallel with the power
supply of the motor in order to absorb energy being fed back.
Connection types
The EL7041 Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.

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
