Initial Setup¶

Avid CNC Plug and Play Spindle Connections¶

Refer to the appropriate setup instructions for your Spindle/VFD package:

• Plug and Play Spindle / VFD System: CRP800 VFD Setup Guide

Avid PRO CNC Plasma System Connections¶

Refer to the PRO CNC Plasma setup instructions: PRO CNC Plasma Instructions

Relay 1 Output Connections¶

Relay 1 is rated for 250VAC and 15A^† AC. The relay requires external AC power to be plugged in to "Relay 1 In" on the CNC controller. This output is commonly used in two ways:

• Control a router: When Avid CNC's version of Mach4 is configured with a router cutting tool, the router should be plugged into "Relay 1 Out". By default it is controlled by either the Router toggle button in Mach4 or by G-code with M03 (spindle ON) and M05 (spindle OFF) commands.

• Control a dust collector, coolant system, or general AC load: When Avid CNC's version of Mach4 is configured with a spindle or plasma cutting tool, relay 1 can be controlled either manually or using G-code. To manually operate the relay, use the relay 1 toggle button. Using G-code, M08 will turn relay 1 on and M09 will turn BOTH relay 1 and relay 2 off.

^† The C13 type relay power plugs/sockets are rated for 15A in North America and 10A in most international regions.

Relay 2 Output Connections¶

Relay 2 is rated for 250VAC and 15A^† AC. The relay requires external AC power to be plugged in to "Relay 2 In" on the CNC controller.

This output is commonly used for dust collection or coolant systems, but can be used for many general AC loads. Relay 2 can be controlled manually in Mach4 with the relay 2 toggle button. The use of G-code to operate relay 2 will depend on your Mach4 configuration.

• Router cutting tool: Use M08 to turn relay 2 on and M09 to turn relay 2 off.
• Spindle or plasma cutting tool: Use M07 to turn relay 2 on and M09 to turn BOTH relay 1 and relay 2 off.

^† The C13 type relay power plugs/sockets are rated for 15A in North America and 10A in most international regions.

3rd Party Spindle/VFD or non-Hypertherm Plasma Torch Connections¶

Use the information below to adapt external equipment to the 14-pin control cable supplied with the Avid CNC Plug and Play controller. The 14-pin female connector is pre-wired into the Plug and Play controller with these functions. Note: "Plasma" wires are only connected in plasma-enabled Plug and Play systems.

14-Pin Control Cable Pinout

Pin 1/2, Fault Signal/Fault Ground: This input is used to read a fault from an external VFD, typically from thermal overload or a disconnected spindle power cable.

Pin 3/4, Torch ON: This output is from a small dry contact relay on the TMC3in1 used to trigger a CNC controllable plasma torch ON/OFF.

Pin 5/6, Voltage Divider: This input is the Tip Voltage used for Torch Height Control (THC). It is critical that the (+)(-) polarity of this signal is correct, as well as the voltage divider ratio. The ratio must be 50:1 (used by Hypertherm and preset in the Avid CNC Mach4 profile), 40:1, 30:1, 20:1, 16.67:1, or 15:1. Note: Do not connect raw tip voltage, this will damage the TMC3in1.

Pin 7/8, Spindle Relay: This output is from a small dry contact relay on the CRP850 breakout board and is used for sending an on/off signal to an external VFD, typically for a forward/stop command.

Pin 8/9, Spindle Analog Signal: This output is a 0-10V analog signal used to control VFD frequency/spindle RPM.

Pin 11, 10V Reference: Unused in most systems, this pin can provide a 10V reference if required by the VFD.

Pin 12/14, Arc Okay: This input signals to the CNC controller that the plasma arc has successfully transferred to the material and the cut program can continue motion. Typically the plasma power supply will close a dry contact relay to control this signal.

Custom M12 Inputs Connections¶

For custom machine applications, the M12 sensor inputs on the CRP860-00E breakout board can be used for purposes other than limits and probes. The inputs are Normally Open, rated for 12V, and follow a standard M12 A-coded pinout. See the Schematics section for more details on pin assignments in Mach4.
