If this operation generates an error message (example Error code 1), check the connections of the power and control circuits (see Step 1 - Connections),

check motor data settings (see Step 2 – Motor data setting) and then repeat the Autotune procedure (or, alternatively, select a different type of procedure

(Rotation or Still)

STARTUP WIZARD

Run autotune rot ?

Step 3A - Self-tuning with rotating motor (Autotune rotation)

Use this procedure when the motor is not coupled or the transmission does not represent more than 5% of the load.

This procedure obtains the most accurate data.

Note !

Autotuning can be cancelled at any time by pressing

At the end of the self-tuning procedure there is a request to open the Enable contact (terminals 7 – S3); the Take tune parameters command (menu 16 MO-

TOR DATA, PAR: 2078) is automatically executed.

The calculated parameters are saved in a RAM memory to enable the drive to perform the necessary calculations. These data are lost if the device is

switched off. To save the motor data follow the procedure described in Step 6.

When the Enable contact is opened the drive proposes Step 4 to proceed with the wizard.

rated speed of the motor; this value must reflect the speed of the fully loaded motor at rated frequency. If slip is indicated on the motor data

plate, set the Rated speed parameter as follows: Rated speed = Synchronous speed - Slip (e.g. for a 4-pole motor Rated speed = 1500 - 70

= 1430).

rated frequency of the motor, as shown on the data plate.

Number of motor pole pairs. The number of motor pole pairs is calculated using the plate data and the following formula:

P = 60 [s] x f [Hz] / nN [rpm]

Where:

P = motor pole pairs, f = motor rated frequency (e.g. 50); nN = motor rated speed (e.g. 1450)
