Control restrictions
• When the extension parameter storage setting has been set to "CPU", the module data initialization can be performed only
while the CPU module status is STOP. Use "[Cd.2] Module data initialization request" for the module data initialization.
• When the extension parameter storage setting has been set to "CPU", the initialized parameters become valid only after
turning the power to the CPU module off and on again or by performing a reset. The CPU module cannot transition to the
RUN state until the power to the CPU module is turned off and on again or a reset is performed.
• The module data initialization processing takes about 10 to 30 seconds. Do not turn on and off the power or reset the CPU
module during the module data initialization processing. Doing so cancels the flash ROM write and the backed up data will
be lost.
Module initialization method
The parameter initialization can be performed by writing the data shown in the table below into the positioning module buffer
memory using the MOV instruction. The parameter initialization is executed at the timing when the data is written into the
positioning module buffer memory.

The module initialization can also be performed by using the GP.PINIT instruction of the dedicated instructions. For details on
the dedicated instructions, refer to the following.
