2 = - Identification with motor rotating

Shaft is rotated during identification.

This identification must be run without load on motor shaft. U/f settings and

magnetization current are identified. This identification should be run regardless of the

final operation mode (closed loop or open loop) to get the best performance from the

motor. When identification with motor rotation is successfully finished the drive starts to

use internal slip estimator to compensate the motor temperature changed.

Example of behaviour

3 = - Encoder identification run

The motor shaft is rotated during identification.

IM: If performed for induction motor encoder pulse number and direction are identified.

Can be used if the is no encoder information available, correct result can be achieved

only when motor in unloaded.

PMSM: This selection is used for PMS motor if automatic angle identification is not

suitable for used motor (angle is identified automatically in every start if PMSM Shaft

Position parameter is zero).

This identification run will update PMSM Shaft Position parameter based on absolute

position of the encoder or Z pulse position of incremental type encoder.

Note: Identification needs to be remade if encoder position related to motor is changed

e.g. due maintenance.

4 = - Identified All

Shaft is rotated during identification.

All the above identification selections are made in sequence.

5 Enc.ABS.Lock Absolute encoder when locked rotor

Absolute encoder zero position identification when rotor is locked while using permanent

magnet motor.
