• When setting parameters in the inverter memory control area, the values are
reflected to the inverter operation and saved. Parameters set in other areas via
communication are reflected to the inverter operation, but are not saved. All set
values are cleared following an inverter power cycle and revert back to its previous
values.
Therefore, make sure to save the parameter after setting the parameter of a
different area as communication and before turning off the inverter power. But it is
not necessary to save the parameter at the inverter memory control area and the
value will be saved to the inverter immediately once the setup is complete.
• Define the parameter carefully. After setting a parameter to 0 via communication,
set it to another value. If a parameter has been set to a value other than 0 and a
non-zero value is entered again, an error message is returned. The previously-set
value can be identified by reading the parameter when operating the inverter via
communication.
• The addresses 0h03E7 and 0h03E8 are parameters for entering the password.
When the password is entered, the condition will change from Lock to Unlock, and
vice versa. When the same parameter value is entered continuously, the
parameter is executed just once. Therefore, if the same value is entered again,
change it to another value first and then re-enter the previous value.
For example, if you want to enter 244 twice, enter it in the following order: 244 → 0
→ 244.
It may take longer to set the parameter values in the inverter memory control area
because all data is saved to the inverter. Be careful as communication may be lost during
parameter setup if parameter setup is continues for an extended period of time.
