The power connection terminals for the ENC are located on the controller as shown in the figure below. The ENC requires a 24V DC power supply with an output current of at least 1A. The voltage must not exceed 24V or fall below 24V.
Once the power is connected, the ENC will immediately power on.
⭐ Important Note: For the 24V power supply to the controller, do not connect any other high-power load devices. This is to achieve optimal anti-interference performance and stable operation.
This is particularly crucial if users attempt to use a single 24V power supply to power both the controller and stepper motors/drivers simultaneously.
In such a scenario, the isolation effect provided by the optocouplers in your stepper driver will be rendered ineffective!!
Although the controller itself utilizes an internal isolated power supply module (meaning users do not need a separate dual power supply for the controller’s core functions), and its input/output signals are isolated using optocouplers, you must still ensure that the signals, even after this opto-isolation, are not subjected to interference from high-power or inductive devices.
In other words, the 24V power supply provided to the controller should be exclusively used for control signals and for connecting low-power devices such as proximity switches, tool setters, and similar components.
⭐: Can I use my 24V 10A power supply? Yes, you can. The amperage rating on the power supply indicates the maximum amount it can output (load capacity). Since the ENC requires at least 2A and 10A > 2A, it is perfectly suitable!
