• Click OK.
• Click Update RMC.
• The Update Module Configuration dialog box will be displayed to indicate the progress. If the
module could not be reset automatically, you may be prompted to reset the module manually.
4. Wire, Test, and Tune the System
Wiring and testing should follow your design. Tuning the system is described in the RMCWin online
help. Be sure to save your tuning parameters both in the RMC Flash memory and on disk from
RMCWin.
Sample Application
The customer needs a single axis to move between two positions. The first position is the
retracted position for the cylinder and is fixed; this position is defined at 0 inches. The second
position is calculated by the PLC and may be anywhere from 10 to 20 inches, depending on the
measured size of the raw materials coming down a production line.
We will assume that the customer decided 5 inches per second was the maximum safe extension
speed, and that 10 inches per second was the maximum safe retracting speed.
1. Design the System
The RMC controls based on the transducer or encoder counts received. However, counts rarely
correspond to meaningful engineering units. Therefore, the RMC allows the user to convert counts
into meaningful position units by using Scale and Offset parameters. Refer to RMCWins online
documentation for details. In this application, the position units used will be thousandths of an inch.
Therefore, speeds will be given in thousandths of an inch per second.
Because only one axis of MDT feedback is needed, the smallest RMC module availablean
RMC100-M1-DI/O modulewill be used.
2. Program the Profile Table
Because two speeds are required, two motion profiles will be used. As shown in the charts for
selecting profiles and axes above, profiles 0, 2, 4, and 6 are available for axis 0. Therefore, profiles
0 and 2 will be used. The following profile table entries defines the speeds required by the
customer for each move (remember that profile 1 is unused in this example):
Once this Profile table and the desired configuration parameters are stored in the RMC Flash
