Write mode
RAM write mode
Note: When the auto/manual mode is switched with an operation
command through communications and the Controller is in RAM
write mode, the auto/manual status is not stored in EEPROM.
Consequently, if the Controller is restarted by performing a
software reset or turning the power OFF and ON again, the auto/
manual mode is set to the last saved status.
◆ Switching to Manual Mode during Auto-tuning
If the mode is switched during auto-tuning (AT), the AT will be
cancelled and the Controller will be switched to manual mode.
● Parameter Initialization
The present settings are returned to the default values and written to
EEPROM. This command can be accepted in setup area 1 only. When
this command is issued in setup area 0, an "operation error" will be
generated.

00 Default set values (See SECTION 3 Communications Data for
CompoWay/F and SYSWAY for details.) (These settings are the
same as the ones used when "FACT" is selected for the setting
data's set value initialization.)
● Alarm Latch Cancel
The applicable alarm latch can be cleared with the related information
setting. The setting can be accepted in both setup area 0 and setup
area 1. An operation error will occur if communications writing is
disabled or if an EEPROM error occurs.
● Invert Direct/Reverse Operation
Inverting or not inverting direct/reverse operation can be selected with
the related information setting. The setting can be accepted in both
setup area 0 and setup area 1. The related information specifications
are written to EEPROM according to the write mode settings. An
operation error will occur in the following situations:
• When AT is being executed.
• When inverting direct/reverse operation is set for an event input.
• When executed in manual mode.

Description
When the auto/manual mode is switched by commu-
nications, the auto/manual status is not written to
EEPROM. The status can be written with the Con-
troller key operations.
