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

specify the rotation direction that matches the actual rotation direction of the machinery.
When under “V/f control (00

2)” or “Common Dynamic Torque Vector Control (00
．
42 = 1)”,it is
adopted to drive general motor and the wiring between the motor and inverter is too long or reactor is
connected, it requires configuring the basic function parameters or implement auto-tuning for motor
controlling before starting operation. set the function parameters data in the following table according
to the motor ratings on the motor's nameplate.

Machinery design values
Note: For a test-driving of the motor,
increase values so that they are longer
than your machinery design values. If
the specified time is short, the inverter
may not run the motor properly

stopped.Tuning the
no-load current and
magnetic saturation
factor, with the motor
running at 50% of the
base frequency. Tuning
the rated slip frequency,
with the motor stopped.
Under no-load status
(motor idling, not
connect to the
mechanical
transmission part)
Tuning with load
applied decreases the
tuning accuracy.
