Configuring Signals
To set up and wire 24V limit/home switches, follow the steps outlined below.
- On the menu bar at the top of the screen select Configure->Control. Select the Input Signals
- Scroll down through the list until you find the different motor sections (Home, -- , and ++). The example image below shows the inputs scrolled down to the motor home section. Further down is ++ and --.
Figure 24 Input Signals - Enable the limit and home switches by clicking the red [X] (in the Mapping Enabled column) by the signal to make it a green check.
- Note: Each motor has three signals, the max travel (motor ++), the min travel (motor --), and the home (motor home). All three must be enabled and set to the correct device and input name for everything to work correctly using the wiring description above.
- Set the device and input name to the desired input.
- Set up the active low checkbox to a green check for a normally closed switch.
- Note: Under the active low column the active state can be changed by clicking on the [X] or check mark. If the limit switches are normally open the red X should be used. However, this is not recommended as it is not as safe.
- When the limit and home switches for each motor are completely configured, press [Apply] and then [OK].
In the example above, motor 0, 1, and 2 home switches are enabled. All of them are wired normally closed. The device and input name for motor 0 is HiCON [P11] Input1 (X1). Since the switches for each motor are wired in series, the motor ++ and motor -- signals lower down in the list would also have the same corresponding device and input names. Manually trigger each limit switch and make sure they disable Mach before continuing.
