The image shows an overview of all connections of the CNC530.

The board is powered by 24V. We recommend using at least a 1A power supply. Although the board does not use much power, its power depends on things connected to it.

The relay outputs are Normally Open, Normally Closed, and Common, which means you can wire them as you please.

We have also added an extra option. An external power supply can be connected to 'Relay COM'.

This setting can be made for the relevant relay outputs, and it makes it more convenient to make, for example, 5V or 24V outputs of the relay outputs.

Placing the Jumper on + -> Corresponding Relay 'COM' connected to 'Relay power'. Placing the Jumper on - -> Corresponding Relay 'COM' connected to 'Relay ground'. Not placing a jumper -> Corresponding 'COM' is floating and can be used as desired. An external power source can be used.

The CNC530 controller can simultaneously provide a PWM signal and an analog 0-10V signal. Both signals have the same source and can not be controlled individually.



The PWM output is the default so-called open-collector output. This means an external resistor is needed for the signal to be high. If you need a 5V or 12V PWM output signal, you can use a jumper to select either of the built-in resistors. The image below illustrates this.



The CNC530 features 3 ways to connect a motor (driver) to the controller:

Our controller features three important signals.

Step: This output will generate a pulse for the stepper motor input

Direction: This signal indicates whether a motor driver needs to rotate the motor Clock-Wise (CW) or counter-clockwise (CCW)

Enable: This signal indicates when the motor driver needs to power the motor. Typically, if the driver does not have an enable signal with the correct level, you can move or rotate a motor by hand, but this is not possible when the motor is enabled.

The CNC530 features 3 ways of connecting the controller to a motor driver:

This way, you can use the connection that you prefer.

The following outputs are potential-free, due to the use of a relay output:

Each output consists of three pins:

The relays can be connected to a secondary power supply.

As seen in the picture above, the relay output voltage can be controlled by using jumpers. You can use the relay if you don't use a jumper as needed.

The G-code M3 controls the tool output. It switches a tool on. This output is often connected to the input for switching the spindle on through the VFD. The actual speed of the spindle is most of the time controlled by a 0-10V signal.

The G-code M controls the flood output. it switches this output on.

The G-code M controls the flood output. it switches this output on.

The AUX output can be used for any purpose. It's controlled through G-code M5?.

The E-stop output is an extra output that will automatically be activated when the E-stop input is activated. It can trigger other devices, e.g., to control a power relay for switching power to the motor drivers. It can not be manually controlled.



The brake output is an output that is automatically activated when the motor drivers are disabled.



The status output offers the possibility of connecting the external status PCB.

The E-STOP input indicates an emergency. The input signal needs to switch to ground to use E-STOP, as shown in the image below.

The status of the E-Stop input is shown in the software I/O tab:

A RED indicator on the controller also indicates an E-STOP:



When the RESET button is pressed, it will also indicate this on the controller by showing a green light.

The HOME inputs are required for the machine to detect the ‘home’ position.



There are multiple different types of homing switches. They can be PNP or NPN and either Normally Open (NO) or Normally Closed (NC). The CNC530 supports only NPN, both NO and NC.

NPN means that the signal gets switched to the ground if the switch is activated. When using a regular switch, connect one terminal to the ground and the other to the corresponding home input.

NPN means that the signal gets switched to the ground if the switch is activated. When using a regular switch, connect one terminal to the ground and the other to the corresponding home input.

The probe input has two uses. It can measure the length of a tool or probe an object. If both tools are used, they can be connected together to this input. However, make sure that they both use the same output signal.

The AUX input is a dedicated input that can be used for numerous applications:
