“H” Group: Motor Constants Functions
Introduction
The “H” Group parameters configure the
inverter for the motor characteristics. You
must manually set H003 and H004 values
to match the motor. Most of the remaining
parameters are related to vector control, and
are in use only when function A044 is set
for one of the vector control modes as
shown in the diagram. The procedure
in
“Auto-tuning of Motor Constants” on
page 4–71
automatically sets all the param-
eters related to vector control. If you
configure the inverter to use vector control,
we highly recommend letting the auto-
tuning procedure derive the values for you.
If you want to reset the parameters to the
factory default settings, use the procedure
in
“Restoring Factory Default Settings” on
page 6–16
.
NOTE:
The auto-tuning procedure and related warning messages are in
“Auto-tuning of Motor
Constants” on page 4–71
. Please read these before trying to auto-tune the motor parameters.
