D.10 Enter Command

When writing parameters to the bypass from the PLC using MEMOBUS/Modbus communication, parameters become active

immediately. If it is desired to save the parameter value to non-volatile memory, then a separate Enter command must be given.

This section describes the Enter command.

The bypass supports the Enter command as shown in Table C.10. An Enter command is enabled by writing 0 to register number

0900H. It is only possible to write to this register; attempting to read from this register will cause an error.

Table D.6 Enter Command

0900H

Simultaneously writes data into the EEPROM (non-volatile memory) of the bypass and enables the data in RAM. Parameter

changes remain after cycling power.

Note: The EEPROM can only be written to 100,000 times, so it is recommended to limit the number of times writing to the EEPROM. The Enter

command register is write-only and if this register is read, the register address will be invalid (Error code: 02H). An Enter command is not

required when reference or broadcast data are sent to the drive.

Enter Command Behavior

An enter command is not required when writing registers 0000H to 001FH and 8400H to 83FFH. Changes to those registers

cannot be saved to non-volatile memory.

Enter Conditions Behavior

How parameter settings are enabled As soon as the value is changed.

Upper/lower limit check Checks only the upper/lower limits of the parameters that were changed.

Default value of related parameters Default settings of related parameters are changed automatically.

Error handling when setting multiple parameters Error occurs if only one setting is invalid. All data that was sent are discarded.
