Troubleshooting Overview

Tip:
USE THE EVENT LOG! If an error occurred, or something unexpected happens, open the Event Log to see if the command caused any errors.

How to Troubleshoot

RMCTools provides several tools that help you troubleshoot the RMC:

Tools	Description
Event Log	Logs most events that occur on the RMC, including commands, errors, and communications transactions. You can change the Event Log Filtering to log only certain events, or to add events, such as communication transactions.
Plots	Plot any register in the RMC. Track motion and see what happened at each point.
Status Bits	Provides an overview of the state of each axis.
Error Bits	Provides an overview of the errors that have occurred on the axis.

Tips

Use the Event Log Monitor to view the commands you have issued and any errors they may have caused.
Use the Event Log Filtering to log only certain events, or to add events, such as communication transactions.
Add the Status Bits register and Error Bits register to the plot data.

Plots

I can't trigger a plot:

Make sure the plot trigger is enabled. Use the Enable/Disable Plot Trigger (104) command.
Make sure the plot is rearmed. Use the Rearm Plot (103) command.

RUN Mode

The RMC unexpectedly exits RUN mode:

After the RMC exits RUN mode, look at the Event Log. It will likely tell you why it exited RUN mode. Possible reasons are:

A discrete output was set to put the RMC into and out of RUN mode. See the Programming Properties topic for details.
The RMC received a Fault Controller (8) command.
