Types of Enter Commands
The drive supports the two Enter commands shown in
An Enter command is enabled by writing 0 to register number 0900 (Hex.) or 0910
(Hex.).
These registers can be written to only.
An error will occur if the user attempts to read from these registers.
Table 7.4 Types of Enter Commands
Register Number
(Hex.)
Description
0900
When you write parameter data to the EEPROM, you will enable the data on the RAM at
the same time.
Parameter changes remain even if the power supply is cycled.
0910
This updates the data on the RAM, but does not write data to the EEPROM.
Parameter changes are lost when the drive is shut off.
Note:
•
You can write the EEPROM to the drive a maximum of 100,000 times. Do not frequently execute the Enter
command (0900 (Hex.)) that is written to EEPROM. When the command data or broadcast message is
transmitted to the drive, the Enter command is not necessary.
•
Parameter data cannot be written to EEPROM during undervoltage, even using 0900 (Hex.).
•
If undervoltage occurs when a making several parameter changes issued with a single ENTER command, the
writing process may be aborted before all of the new changes have been written. Because all of the data has
not yet been written, the EEPROM data error
CPF06
will be displayed the next time power to the drive is
cycled. To prevent
CPF06
, wait approximately 5 seconds after issuing the ENTER command before shutting
off drive power.
