CHV180 series frequency inverter special for elevator Detailed function description
.36.
leakage inductance of motor can be detected and the mutual inductance and current
without load will not be detected by static autotuning.If needed, user should input
suitable value according to experience.
For synchronous motor, the self-learning current (P4.10) is set to get the magnetic pole
initial position (P4.03).
Note:
Correct the zero-bias value of encoder (P4.08 and P4.09) which is displayed
by Pb.06 and Pb.07 when it is not connected to the encoder.
The direction of encoder (P4.02) must be right.When the inverter is
forwarding, the motor is counterclockwise rotation seen from motor shaft
side, and the direction of encoder is set to be forward.
When autotuning, the actual current (Pb.03) should be between 80.0% and
110%, or adjust P4.10.
Continuous autotuning for 3 times, if the deviation of each magnetic pole
position is less than 10 degrees, it shows the autotuning is right, otherwise if
the magnetic pole is more than 10 degrees, it must be reautotuned.
Static autotuning is valid for SIN/COS encoder, and rotation autotuning is
suitable for UVW encoder.
