1. परिचय
The Emiif ZK-SMC02 is a dedicated operation control module designed for single-axis stepper motors. This versatile module integrates both controller and driver functionalities, eliminating the need for a separate driver in many applications. It features a variety of built-in fixed operating modes, allowing users to quickly select the appropriate motion path for their needs. Key parameters such as distance, speed, delay, and cycle count can be stored and adjusted, even after power-off. The ZK-SMC02 can operate independently or be integrated into larger systems. It is suitable for general industrial control applications but should not be used in critical areas such as medical treatment, fire protection, or life-critical systems.
