RMC70/150 and RMCTools User Manual
Note: It is possible to add more analog inputs than can be assigned to axes. However, it is
still possible to view the voltage of the extra analog inputs using the Analog Input Registers.
Inputs that are unassigned to axes can have no status bits, error bits, scaling, filtering, etc.
7.2.5.2. Adding an Expansion Module to a Controller
To add an expansion module to an RMC70 controller:
1. Disconnect power to the RMC70.
2. Remove the 4 screws on the far right side of the top and bottom surfaces of the
controller.
3. Plug the expansion module into the right side of the controller.
4. Install the 4 screws into the same holes they were removed from in step 2.
5. Apply power to the RMC70.
6. Open RMCTools and open your project. If you do not have a previous project, start a
new project and do not continue this procedure.
7. Go online with the controller. If the Controller Hardware/Firmware Differences dialog
opens, click Go Online. Save the project. On the controller menu, click Update Flash
to save the RMC70 settings to Flash memory.
If you are not able to go online with the controller, you can configure your project in
RMCTools to include the expansion module as follows:
• Right-click the controller and click Properties.
• Click Add Module, select the module you just added, and click OK.
• Click OK, download the settings to the controller, and go online with the
controller.
7.2.5.3. A2 Expansion Module
The 2-input Analog expansion module (A2) is one of the optional expansion modules available
for the RMC70 series motion controller. This module provides two analog inputs with 16-bit
resolution.
The A2 should not be confused with the AP2, which provides analog input with support for
pressure control. If you do not require position-pressure/force or control, you do not need the
AP2.
Note: Using the A2 module, it is possible to add more analog inputs on the RMC70 than can
be assigned to axes. However, it is still possible to view the voltage of the extra analog inputs
using the Analog Input Registers. Inputs that are unassigned to axes can have no status bits,
error bits, scaling, filtering, etc.
Features
• Two 16-bit voltage or current inputs - each individually selectable
