H" Group: Motor Constants Functions - Hitachi L2002 Instruction Manual

"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.
