N700E INSTRUCTION MANUAL
5.6
Sensorless Vector Control
Function description
The N700E inverter has a built-in auto-tuning algorithm.
The N700E inverter can be possible to do high-starting torque and high-precision operation.
The required torque characteristic or speed control characteristic may not be maintained in case
that the inverter capacity is more than twice the capacity of the motor in use .
Function setting method
Select the parameter A31 to 2 (sensorless vector control).
Parameter H03 and H04 select motor capacity and poles (example 4 for 4-poles).
Parameter H02 selects which data(standard data, auto-tuning data) of motor constants you want
the inverter to use.
※ N700E-1600HF/2000HFP ~N7000E-3500HF/3800HFP do not support Sensorless Vector Control
