Automatic motor identification (energized)

The automatic identification of the motor results in the best possible parameter settings. If the application enables you to energise the system during the optimization, carry out this optimization.

Conditions

The motor must be cold and at a standstill.

–

All rated motor data are known and set in the inverter, either by selecting the motor from the motor catalog or manually:

–

Select motor from motor catalog

–

Manual setting of the motor data

–

In 0x2C00 (P300.00), the motor control type required is suitable for the motor selected.

–

In 0x6060 (P301.00), the operating mode "MS: Velocity mode [-2]" or "CiA: Velocity mode (vl) [2]" is set.

–

DC-bus voltage is available.

–

The inverter is error-free and in the "Ready to switch on" or "Switched on" device state.

–

The motor is stopped (no start enable).

–

No inverter disable is active.

–

No quick stop is active.

–

No other axis command is active.

General information on the identification

–

The automatic identification can take from some seconds to minutes.

–

The procedure can be aborted any time by inverter disable or cancellation of the start enable without settings being changed.

–

During calibration and after the calibration has been completed successfully, the blue LED display is constantly on. As soon as the identification has been executed and the device is deactivated, the LED changes to a blinking mode.

–

After completion, a renewed start command is required to start the motor.

Required steps

Optimization with engineering tool (e. g. »EASY Starter«):

1.

Go to the "Settings" tab and navigate to the parameterization dialog "Advanced motor setting".

2.

Press the Energized button under "motor calibration".

3.

Follow the instructions of the engineering tool.

Optimization with keypad:

1.

Request automatic identification: Set 0x2822:004 (P327.04) = "1".

2.

Issue the start command to start the procedure.

3.

The motor calibration is performed.

4.

After completion, issue the start command again.

In order to achieve the most optimum behavior for the user, the parameters listed below can be used to influence the motor identification.

Parameter

Address	Name / setting range / [default setting]		Information
0x2822:004 (P327.04)	Identify motor data (energized) (Identify mot.) 0 ... [0] ... 1		1 = start automatic identification of the motor data. – Inverter characteristics, motor equivalent circuit diagram data and controller settings are identified and set automatically. – During the procedure, the motor is energised!
0x2DE0:009	Service settings: Motor identification settings 0 ... [0] ... 65535 – Setting can only be changed if the inverter is disabled. – From version 05.03		Setting for motor identification.
0x2DE0:009	Bit 0	Activate switching frequency (0x2939)	Bit 0 = 0: the identification algorithm uses the 4 kHz switching frequency (standard). Bit 0 = 1: the identification algorithm uses the switching frequency configured in the parameter 0x2939 (P305.00).

Optimization process

As soon as the process has been started, the following steps are initiated:

1.

The inverter characteristic is automatically identified by the inverter.

2.

The motor equivalent circuit diagram data are automatically identified by the inverter.

3.

The motor controller settings are automatically calculated.

4.

The speed controller settings are automatically calculated.
