N700E INSTRUCTION MANUAL
5-30
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 bemaintained 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 motorconstants you want
the inverter to use.
