Section 7: Motor and Sensor Connections¶
Axis Nomenclature Update (April 2021)
The nomenclature used to describe the dual-driven Y axis changed in April 2021 to "Y1" axis and "Y2" axis. If you purchased your Plug and Play CNC Control System prior to this, refer to the Plug and Play CNC Control System Previous Revision notes throughout this section. These will provide instructions that match the motor and sensor labels on your control box.
7.1 Motor and Sensor Locations¶
7.1.1¶
7.1.2¶
Plug and Play CNC Control System Previous Revision
Plug and Play CNC Control Systems purchased prior to April 2021 use the nomenclature shown below for proximity limit switches.
7.1.3¶
Plug and Play CNC Control System Previous Revision
Plug and Play CNC Control Systems purchased prior to April 2021 use the nomenclature shown below for motors.
7.2 Cable Routing¶
7.2.1¶
| Motor/Sensor | Cable Routing Path |
|---|---|
| Y1- Switch | Directly to control box |
| Y2+ Switch | Directly to control box |
| Y2- Switch | Directly to control box |
| Y1 Motor | Directly to control box |
| X- Switch | Through table cable track |
| X+ Switch | Across gantry and through table cable track |
| X Motor | Through table cable track |
| Z Motor | Through table cable track and gantry cable track |
| Z+ Switch | Through table cable track and gantry cable track |
| Y2 Motor | Directly to control box |
Plug and Play CNC Control System Previous Revision
Plug and Play CNC Control Systems purchased prior to April 2021 use the following cable routing paths.
| Motor/Sensor | Cable Routing Path |
|---|---|
| Y- Switch | Directly to control box |
| Y+ Switch | Directly to control box |
| Slaved Switch | Directly to control box |
| Y Motor | Directly to control box |
| X- Switch | Through table cable track |
| X+ Switch | Across gantry and through table cable track |
| X Motor | Through table cable track |
| Z Motor | Through table cable track and gantry cable track |
| Z+ Switch | Through table cable track and gantry cable track |
| Slaved Motor | Directly to control box |
7.2.2¶
- Route the indicated motor cables as shown. The remaining two motor cables can be routed directly to your control box without going through cable track.
Cables
| Axis | Color | Cable |
|---|---|---|
| X Motor | Red | 12' |
| Z Motor | Blue | 20' |
7.2.3¶
- Route the indicated sensor cables as shown (see table on next page). The remaining three sensor cables can be routed directly to your control box without going through cable track.
Assembly Note
The X+ sensor cable is routed on top of the gantry, but not inside the gantry cable track.
Assembly Note
If using an Avid CNC Plug and Play CNC Control System purchased after October 2019, you will plug the X+ sensor cable into the "A" sensor port on the control box.
Cables
| Axis | Color | Cable |
|---|---|---|
| X- Sensor | Red | 12' |
| X+ Sensor | Pink | 20' |
| Z Sensor | Blue | 20' |
7.2.4¶
- To route cables through the cable track, use a screwdriver to lift open the individual cable track sections as indicated.
7.3 Sensor Installation¶
Parts and Tools Required¶
| QTY | Part/Description | Packaged In |
|---|---|---|
| 1 | Proximity Sensor Kit | Electronics |
| (6) Cylindrical Proximity Sensors | ||
| Proximity Cables (See table in Step 7.2.2Step 7.2.2 for lengths) |
- Required Tools:
- Adjustable Wrench
