Product Description:

The EL6851-0010 terminal utilizes compact drive technology to facilitate direct motor connection and feedback for stepper motors. It is a Beckhoff terminal that is suited for applications requiring precise control and reliable performance in motion systems. The terminal supports two inputs for end position detection and one input for an encoder, providing essential feedback for effective motor control. It is designed to operate with 2-phase stepper motors, ensuring versatility in various applications. It features a single output channel dedicated to controlling one stepper motor. This streamlined design allows for focused and efficient control of mid-power range stepper motors.

The terminal allows for a configurable step frequency of up to 8000 full steps per second. This high frequency enables precise and rapid control of the stepper motor, allowing for smooth and accurate positioning in various applications. It provides a 64-fold microstepping capability, which divides each full step into smaller increments. This feature enhances the motor's resolution, resulting in finer control and smoother motion. This terminal operates with a supply voltage of24 V DC delivered through power contacts. This ensures stable performance and communication with connected components. It can accept an external power supply voltage range of 8 to 48 V DC. This flexibility allows users to connect a variety of power sources, accommodating different system requirements.

The EL6851-0010 supports a maximum output current of 5.0 A, making it suitable for driving mid-range stepper motors. The terminal complies with EMC immunity and emission standards, specifically EN 61000-6-2 for immunity and EN 61000-6-4 for emission. It is suited for 0 to +55°C operating temperatures and also boasts moderate ingress protection with a rating of IP 20.
