“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.
NOTE: If you are using automatic torque boost (A041/A241 = 01) and the output
current is unstable in the low frequency range, be sure to adjust A042/A242 and
A043/A243 with H006/H206 in order to decrease the boost voltage as an addition to the
standard V/f curve.
