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
