A1.2 Setting and Change of Basic Parameters
This section describes procedures to set and change the parameters for each block. Obtaining
access to each parameter differs depending on the configuration system used. For details, refer
to the instruction manual for each configuration system.
(1) Access the block mode (MODE_BLK) of each block.
(2) Set the block mode (MODE_BLK) target
(note 1)
to Auto, Man or O/S
(note 2)
in accordance with
the Write Mode of the parameter to be set or changed.
(3) Access the parameter to set or change.
(4) Make setting or change in accordance with each parameter.
(5) Set the Target of block mode (MODE_BLK) to Auto
(note 2)
.
IMPORTANT
Do not turn the power OFF immediately after setting parameters. To improve the reliability of the
device, processing to store data to EEPROM is duplexing. If the power is turned OFF within 30
seconds after setting of parameters, changed parameters are not saved and may return to their
original values.
Note 1: Block mode consists of the following four modes that are controlled by the universal parameter
that displays the operating condition of each block.
Target (target mode) : Sets the operating condition of the block.
Actual (actual mode) : Indicates the current block operating condition.
Permit (permit mode) : Indicates the operating condition that the block is allowed to take.
Normal (normal mode) : Indicate the operating condition that the block will usually take.
Note 2: The operating conditions which the individual blocks can take are as shown below for each block.

NOTE
For various setting changes, there is a mode which allows each parameter to be written.
If a parameter cannot be rewritten, check for write mode columns in parameter lists in Chapter 6.
