Schneider inverters support two main operation methods for speed adjustment: acceleration and deceleration. Here's a detailed breakdown of each method: 1. **Button Click Operation Method**: This approach requires two logic inputs to control the speed reference. For example, you can assign LI5 as the acceleration function and LI6 as the deceleration function. When LI5 is activated, the speed reference increases. Conversely, when LI6 is triggered, the speed reference decreases. This allows for direct and intuitive speed control during operation. 2. **Double-Click Button Operation Method**: In this mode, only one logic input needs to be assigned to the “+speed” function, such as LI5. Using a double-click on the button enables you to increase or decrease the speed. For instance, if the inverter is running in the forward direction (LI1 is active), pressing the “+speed” button (e.g., LI5) once will increase the speed reference. If you release LI5 while keeping LI1 active, the speed value remains stable. However, if you disconnect LI1 for a moment and then reconnect it, both the speed reference and actual speed will drop. Refer to Table 1 for more details.

These operation methods provide flexibility depending on the user’s preference and application requirements. Whether using a single-button double-click or dual-button control, the system ensures smooth and accurate speed adjustments, making it ideal for various industrial automation scenarios.
