Product Description:

The EtherCAT terminal EL7031-0030 showcases an ability to interface directly with a stepper motor and process analog inputs within EtherCAT-based control architectures. It is manufactured by Beckhoff and it uses durable designs to enhance the operational effectiveness of machines.

The terminal EL7031-0030 provides high-class drive technology for precise control of stepper motors in industrial automation systems. It has a direct motor connection and integrates two analog inputs each operating within a range of 0 to 10 V and a resolution of 12 bits which allows for external controlling signals such as speed or position references. It is suitable for controlling a 2-phase stepper motor which aids in supporting both unipolar and bipolar configurations. It works on a single channel and includes one output specifically motor control purpose. The output current capacity is 2.8 A by making it suitable for small to medium motor loads. It functions with a configurable step frequency of up to 8000 full steps per second by allowing for smooth control. Its 64-fold micro-stepping pattern enhances precision by reducing vibration and improving motion fluidity especially at lower speeds.

The EL7031-0030 terminal’s current controller processes at approximate cycles of 25 kilo Hertz by providing efficient current regulation to the motor coils. With a resolution of approximately 5000 positions per revolution, it allows detailed positioning tasks and smooth movement transitions. It includes distributed clocks functionality which ensures synchronization across multiple terminals within an EtherCAT network by improving timing accuracy. It also includes travel distance control which supports domains requiring predefined movement ranges. The 2-consistent inputs further expand the terminal’s application range by enabling sensor feedback or manual control integration.
