MPG through binary inputs
Main window: Basic functions:
Mpg/Encoder throught binary inputs
- To activate the MPG, it is necessary to check the box next to the MPG number:
- MPG - designed for manual control of the CNC without resorting to controlling the system from the operator panel. With the help of the control panel, the operator of the CNC machine can change the position of the axes, change the feedrate, adjust the spindle operation, set “0” and perform other operations while in close proximity to the workpiece.
- MPG examples are shown below:
- After activation, you can select the operating input numbers for the MPG on the controller - input1 and input2
input1: input2:
- Timing diagram for the MPG signals:

- It is also necessary to select the MPG function:
Functions | Discriptions |
---|---|
MPG wheel | Direct control of the MPG |
THC/Z axis offset | Controlling the tracking (torch height control) while cutting with the help of an MPG |
Spindle Sync | Spindle control, via the analog output to control the spindle speed. |
- If necessary, select the coordinate axis, which will be controlled by the MPG
- Next we select the length of displacements with the help of an MPG. Number of movements in mm per pulse MPG:
- We set the resolving power of the MPG - the number of pulses per one revolution of the MPG
NOTE: The ET7 controller has two encoder slot reserved for the ET7 keyboard panel. These are permanently assigned to inputs #16, 17, 18, and 19, and cannot be changed despite editing the Config window (the preset cannot be overridden). If encoder input slots are to be used on the ET7 board, the latter two slots (2 and 3) should be used. This preset is not present on the ET6/ET10/ET15 boards where encoder slots 0-3 can all be used.
Mpg/Encoder ET10 throught binary inputs
If you use the ET10 controller https://shop.pv-automation.com/et10/9-mycnc-et10.html, you can utilize not only the MPG function, but also the dedicated encoder inputs, to monitor the current position of any of the machine axes. In this way, it is not necessary to specify two binary inputs but rather one specific encoder input.
- To activate the MPG or Encoder, it is necessary to check the box next to required MPG/encoder number:
- After activation, you can select the encoder number on the controller for to specify which encoder will be operated
- It is also necessary to select the MPG function (MPG wheel/THC/Spindle Sync):
Functions | Discriptions |
---|---|
MPG wheel | Direct control of MPG |
THC/Z axis offset | Controlling the tracking (THC) while cutting with the help of an MPG |
Spindle Sync | Spindle control, via the analog output to control the spindle speed. |
- If necessary, select the coordinate axis which will be controlled by MPG
- Next we select the length of displacements with the help of MPG. Number of movements in mm per pulse MPG:
- We set the resolving power of the PGM - the number of pulses per one revolution of PGM
