Troubleshooting and Maintenance

Restoring Factory Default Settings

You can restore all inverter parameters to the original factory (default) settings, for the intended country of use. After initializing the inverter, use the powerup test in Chapter 2 to get the motor running again. To initialize the inverter, follow the steps below.

1.First, check the value of function code B85. The initialization in step 2 will restore defaults for the country code programmed in function B85:

00 = Japan (do not set), 01 = Europe, 02 = United States

Please do not change this setting unless you are absolutely sure the power input voltage range and frequency match the country code setting.

2.Initialization - this uses function code B84. Follow the steps in the table below.
