“H” Group: Motor Constants Functions
Introduction
The “H” Group parameters configure the
inverter for the motor characteristics. You
must manually set H_03 and H_04 values to
match the motor. The remaining parameters
are related to sensorless vector control (SLV),
and are in use only when function A_44 is set
for SLV as shown in the diagram. The proce-
dure in “
Auto-tuning for Sensorless Vector
Control” on page 4–35 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 procedure in “
Restoring Factory Default Settings” on page 6–8.
NOTE: The auto-tuning procedure and related warning messages are in “Auto-tuning
for Sensorless Vector Control” on page 4–35. Please read these before trying to auto-
tune the motor parameters.
