6 PARAMETER
For simple variable-speed operation of the inverter, the initial setting of the parameters may be used as they are. Set the
necessary parameters to meet the load and operational specifications. Parameter setting, change and check can be made
from the operation panel. For details of parameters, refer to the instruction manual.
In the initial setting, all parameters are displayed. Set
Pr. 160 Extended function display selection
as required.
