Restoring Factory Default Settings
You can restore all inverter parameters to the original factory (default) settings according to
area of use. After initializing the inverter, use the powerup test in Chapter 2 to get the
motor running again. If operation mode (std. or high frequency) mode is changed, inverter
must be initialized to activate new mode. To initialize the inverter, follow the steps below.
(1) Select initialization mode in b084.
(2) If b084=02, 03 or 04, select initialization target data in b094.
(3) If b084=02, 03 or 04, select country code in b085.
(4) Set 01 in b180.
(5) The following display appears for a few seconds, and initialization is completed with
d001
displayed.
* Please change from"04 (Basic display)" to "00 (Full display)" in parameter
B037 (Function code display restriction), in case some parameters cannot be displayed.
