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

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
