9.2.4 Changing Parameter Values: General Procedure
For working with parameters, you can use the general commands (p. 232) and the commands
for quick access (p. 232).
For simpler access to parameters, PIMikroMove is used in the following, so you do not have to
deal with the corresponding commands.
Unsuitable parameter settings!
The values in the nonvolatile memory are loaded to the volatile memory as default values
when switching on or rebooting the C-863.12 and take effect immediately. Unsuitable
parameter settings can cause damage to the connected mechanics.
➢ Change parameter values only after careful consideration.
➢ Save the current parameter values to the PC (p. 233) before you make changes in the
nonvolatile memory.
The following procedure is generally recommended for changing parameter values:
1. Change the parameter values in the volatile memory.
2. Check whether the C-863.12 works correctly with the changed parameter values.
If so:
➢ Write the changed parameter values into the nonvolatile memory.
If not:
➢ Change and check the parameter values in the volatile memory again.
The write access for the parameters of the C-863.12 is defined by command levels. After the
controller is switched on or rebooted, the active command level is always 0. On command
levels > 1, write access is only available to PI service personnel.
➢ Contact the customer service department if there seem to be problems with parameters of
command level 2 or higher (p. 259).
