4.1.5 The basic function parameters of V/f control with speed sensor/ dynamic
torque vector control with speed sensor to set and auto-tuning. <3>
Under V/f control with speed sensor 00.42* = 3) or dynamic torque vector control with speed sensor
(00.42* = 4), any of the following cases requires configuring the basic function parameters given
below and auto-tuning. set the Function parameters data in the following table according to the
motor ratings on the motor's nameplate.

Auto-tuning procedure
(1) Selection of auto-tuning type
Select “tuning with the motor stopped (03
.
04* = 1)” or “tuning with the motor running (03
.
04* = 2)”.
For the latter tuning, set appropriate acceleration and deceleration (00
