It is highly recommended H41 –[Auto tuning] be done prior to proceeding operation via Sensorless vector control. Ensure that the following parameters are entered correctly for high performance in Sensorlessvector control. H30: Select motor type connected to inverter output. H32: Enter rated slip frequency based on motor nameplate RPM and rated frequency (See 8-8). H33: Enter motor nameplate rated current. H34: After removing the load, select H40 – [Control mode select] to 0 {V/F control} and run themotor at 60Hz. Enter the current displayed in Cur-[Output current] as motor no load current. If itis difficult to remove the load from the motor shaft, enter the value either 40 to 50% of the H33– [Motor rated current] or the factory default. In case that occur torque riffle while high speed driving, lower H34-[No load current] to 30%. H42, H44: Enter the value of the parameter measured during H41 – [Auto tuning] or the factorydefault. F14: This parameter accelerates the motor after pre-exciting the motor for the set time. Theamount of the pre-exciting current is set in H34- [Motor no load current]. Directly enter the motor nameplate value except motor rating when 0.2kW is used.8-14
