Parameter Error Values

The Parameter Error bit in each axis’s Status word is used to indicate a wide range of problems. This bit indicates that, either directly or indirectly, a command given to the RMC by the user cannot be executed as requested. However, it is not always obvious as to exactly what was wrong with the issued command. Therefore, the RMC has Last Parameter Error registers that hold an integer value for each axis. This integer value latches to the value of the last parameter error received. Therefore, it will not be cleared even if the Parameter Error bit itself clears.

RMCWin reads these registers when it detects the Parameter Error bit on an axis and it reports a text message corresponding to that error number. By using the Windows | Parameter Error List, the user can review the last parameter errors on each axis and receive error-specific help.

It is also possible to read the Last Parameter Error Registers from your PLC when using the RMC’s Ethernet, Modbus Plus, or PROFIBUS (in Message Mode) communication modules. See the appropriate RMC Register Map topic for the addresses of these registers.

The purpose of this topic is to list the possible values you may receive from these registers, list a short description of each, and provide a link to a more detailed discussion on the problem. Click on the description text to jump to the topic with details on the error.
