“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.
