If H40[Control mode Selection] is set to “3”, Sensorless vector control will become active.

!

ATTENTION:Motor parameters should be measured for optimal performance. It is highly recommended H41 [Auto tuning] be done prior to operating via Sensorless vector control.

Ensure that the following parameters are entered correctly for optimal performance in Sensorless vector control.

P30: Select motor type connected to inverter output.

H32: Enter rated slip frequency based on motor nameplate RPM and rated frequency (See 10-6).

P32: Enter motor nameplate rated current.

H34: After removing the load, set H40[Control mode Selection] to “0” [V/F control] and run the motor at 60Hz. Enter the current displayed in Cur-[Output current] as motor no load current. If it is difficult to remove the load from the motor shaft, enter a value equal to 40 to 50% of H33[Motor rated current] or the factory default.

H42, H44: Enter the value of the parameter measured during H41[Auto tuning] or the factory default.

F14: This parameter accelerates the motor after pre-exciting the motor for the set time. The amount 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.
