電動驅動器已成為工廠和過程自動化領域不可或缺的裝置。其優勢顯而易見：這些設備不僅在運作方面特別經濟，而且可輕鬆進行控制和配置。當然，這些優勢也適用於 Festo 電動阻擋缸，這可使輸送的物品停止，因此實現物料流的自動化。
Festo 開發的 EFSD 電動阻擋缸專為傳送系統設計而成，可協助該系統將物體從一個加工站運送到另一個加工站。這可僅憑兩顆螺絲直接固定到傳送系統的型材上，此外輸入和輸出訊號也各需要一個電氣螺紋連接。除了易於安裝，這款電動阻擋缸的另一個亮點是可調節的阻尼，並且透過數位 I/O 進行控制，透過 PLC 可編程邏輯控制器輸出感測器訊號，甚至直接接收指令，因此進行減震和停止。
The electric stopper EFSD has an integrated motor controller and a combined interface to the power supply. This allows it to be connected directly to the digital I/O of a PLC, and it only has a single energy source, so it does not require compressed air. The power supply, communication and logic processing functions are all integrated in the device itself. The EFSD uses LEDs for status indication and for status and error messages, while the sensor and actuator signals are transmitted via M12 plugs.
The EFSD enables conveyed goods from 0.25 to 100 kg to be gently stopped. It is our attractive solution for quickly and easily equipping transfer systems, completely without compressed air, and is available in three different sizes.
The electric stopper EFSD has three positions. In position 1, the initial position, the stop of the stopper cylinder is extended and ready to stop the conveyed goods. In this position, the LED status message is "Closed" and the input signal is 0.
In position 2, the holding position, the conveyed goods have been cushioned and slowed down by the cushioning built into the electric stopper and are then held in position for a certain period of time. In this position, the LED status message is also "Closed" and the input signal is 0.
Only in position 3, the release position, does the LED status message change to "Open" and the input signal to 1. In this position, the stop of the electric stopper is retracted and the conveyed goods are released.
