The exception response has the field configuration shown in the following table.
The detailed field configuration is shown below. The function code of the exception response is the
value of the query function code to which 80h is added. The exception code shows the cause of
exception response.
To Save the Change to the Holding Register (Enter Command)
Even if using the command to write into the holding register (06h) or into the consecutive holding
registers (10h), no change can be saved in the Inverter's memory element. If the Inverter power
shuts off without saving any changes, the holding register returns to the status before the changes
were made. To save the holding register changes in the Inverter's memory element, the "Enter
Command" must be issued according to the following procedure.
To issue the Enter command:
Write into all memory write (holding register number 0900h) using the writing command into the
holding register (06h). In this case, a random value can be written into the holding register.
Notes:
• The Enter command needs considerable time. Monitor the data writing signal (coil number 001Ah)
to check whether the data is being written.
• Since the Inverter's memory element has a limit on the number of rewrites (approx. 100,000 times),
the Inverter life may be shortened if enter commands are frequently used.
