 Parameters
Precautions for Correct Use
• The constants of standard induction motor (IE3 motor) are used as default in the factory set-
ting. If you use standard induction motor, expected characteristics will be achieved without
offline auto-tuning in most cases.
• Smooth tuning could be done if the offline auto-tuning is first performed for the factory-set
parameters.
• If you use a synchronous motor SM (or permanent magnet motor PMM), perform the Control
mode selection, 1st-motor [AA121] is set to 11 (SM/PMM: Synchronous activation) or 12
(SM/PMM: IVMS activation).
• If expected characteristics cannot be achieved, adjust the parameters and motor constants.
• Perform the offline auto-tuning before using the online auto-tuning function.
• The motor constants are for a single phase of Y-connection.
• The offline auto-tuning is performed only when the operation can be made.
• If no-load current is not known, check the current in the operation at the base frequency with
the V/f control by using an electric current monitor and enter the value to [Hb116] before the
auto-tuning.
• Even if 01 (non-revolving) is chosen for [HA-01], the motor could make a half-turn at the max-
imum.
• The offline auto-tuning automatically overwrites the parameters with acquired data. The
online auto-tuning does not overwrite the parameters with the data as it corrects internal
data.
