• 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: 244 0 244.
