.

Parameter values can be read by pressing the center of the setting
dial (the default setting is :V/F constant).

Rotate the setting dial to the right, and change the parameter to 

.
 
Press the center of the setting dial to save the changed parameter.
 and parameter set value “” are displayed alternately.
Caution:
When the V/F control mode selection  is set to : Automatic torque boost control, : Vector control,
or : Energy-saving, be sure to set the following parameters according to the motor's name plate.
 : Base frequency 1 (rated frequency)
 : Base frequency voltage 1 (rated voltage) 
 : Motor rated capacity 
 : Motor rated current
 : Motor rated speed
Set the other motor constants as necessary
1) Constant torque characteristics
Setting of V/F control mode selection  to  (V/F constant)
This is applied to loads with equipment like conveyors and cranes that require the same torque at low
speeds as at rated speeds.
