“H” Group: Sensorless Vector Functions
The “H” group parameters configure the
inverter for the motor characteristics. You
must manually set H03 and H04 values to
match the motor. The remaining parame-
ters are related to sensorless vector control
(SLV), and are in use only when function
A44 is set for SLV as shown in the
diagram. The auto-tuning procedure on
page 4–30 automatically sets all the
parameters related to SLV. If you config-
ure the inverter to use SLV, 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 factory default initialization
procedure on page 6–8.
NOTE: The auto-tuning procedure and related warning messages are on page 4–30.
Please read these before trying to auto-tune the motor parameters.
