RS-485 Communication Features
• 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. When setting parameters via
communication, ensure that a parameter save is completed prior to shutting the inverter
down.
• Set parameters very 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:
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.
