1.Command Codes and Related Information
2.Operation Commands and Precautions
• RUN/STOP
Command code 01 is used to start and stop operation. It is also used to clear errors when an
error has occurred or a protective function has operated. RUN/STOP can be used only in setup
area 0.
• Frequency References 1 to 4
Command code 02 is used to switch between four frequency references that are set in ad-
vance. All four frequency references can be recorded in the Inverter. Frequency References 1
to 4 can be used only in setup area 0.
• Forward/Reverse Operation
Command code 03 is used to change the direction of motor rotation and can be used regard-
less of the RUN/STOP status. The direction will return to forward rotation whenever the power
supply is turned ON or setup area 1 is entered. An operation error will occur if reverse opera-
tion is set in the related information when reverse operation is prohibited. The Forward/Re-
verse Operation can be used only in setup area 0.
• Write Mode
Command code 04 is used to set the mode for writing frequency references using communi-
cations. The Write Mode can be used only in setup area 0. (The default setting for the write
mode is Backup Mode.)
• Backup Mode: The frequency reference is written to EEPROM using communications.
• RAM Mode: The frequency reference cannot be written to EEPROM using communications. Chang-
es to the frequency reference made with key operations are written each time to EEPROM. When
frequently changing the frequency reference, use RAM Mode.
• Save RAM Data
Command code 05 is used to write the frequency reference to
EEPROM using communications.
RAM data can be saved in setup area 0 or 1. The write mode will not be changed.
• Parameter Initialization
Command code 06 is used to initialize all parameters except for the Accumulate Operating
Time to their default values. Parameters can be initialized only in setup area 1.
