Parameter Setting Range
Parameters are used to allocate user memory area or the use range of the
functions.
The parameter data is stored in the first 3K bytes in the user memory area.
(1) Default values
Each parameter has a default value as indicated in Table 4.9.
It is not necessary to change parameter data; programs can be run with
default settings.
(2)
Changing parameter setting
Parameter settings can be changed in the range as indicated in Table
4.9 to meet specific operation needs. A peripheral device should be
used to change the setting.
See the Operation Manual for the peripheral device to be used for the
procedure to set the parameter data.

(2) When comment capacity is set with a peripheral device, 1K byte area is automatically taken
in addition to the setting; the comment capacity displayed is, therefore, 1K byte larger than
the set value.
