“H” Group: Motor Constants Functions
The “H” Group parameters configure the
inverter for the motor characteristics. You must
manually set H003 and H004 values to match
the motor. Parameter H006 is factory-set. If you
want to reset the parameters to the factory
default settings, use the procedure in
“Restoring Factory Default Settings” on page 6-
8. Use A044 to select the torque control
algorithm as shown in the diagram.
