1

Measures the electrical characteristic of Both Induction and Permanent Magnet motors.

Following completion of the auto-tune, the parameter automatically returns to 0.

This Auto-tune measures and populates the following parameters: P4-24 (Stator R), P4-25 (Rotor R), P4-26 (Stator Ind 1), P4-28 (Mag Current), P4-27 (Stator Ind 2).

IM / PM

2

Measures the Encoder Offset of Permanent Magnet Motors using Signal Injection and is required in addition to Auto-tune 1.

The encoder offset uses the Encoder to measure the angular position (Encoder Offset) of the magnetic flux in order to accurately control the motor torque.

This Auto-tune measures the Encoder Offset and populates the following parameters: P6-09 (Encoder Offset)

If the drive trips on AtF-06 it means that the motor has surface mount magnets and the alternative Encoder Offset measurement is required (P4-08=4)

PM

3

Performs Auto-tune 1 and then Auto-tune 2.

PM

4

Measures the Encoder Offset of Permanent Magnet Motors using Current Pulses and is an alternative to Auto-tune 2, this method should be used for Surface-Mount Magnet type motors or if the drive has tripped AtF-06.

This Auto-tune measures the Encoder Offset and populates the following parameters: P6-09 (Encoder Offset)
