EL7031 - General connection examples

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.

Notice

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!

Notice

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 EL7031 Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.
