• You can simultaneously download splines to all spline-capable axes at one time.
• It is important that you avoid trying to download a spline from RMCWin’s curve tool while
downloading through the Spline Download Area.
5.9.3 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
