If H40 [Control mode select] is set to 3, Sensorless vector control will become active.
CAUTION
Motor parameters should be measured for high performance. 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 Sensorless
vector 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 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 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 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.
