NOTE:
Before running the identification process, information from the motor nameplate must be set in the drive.

ID with run
To perform this function, go to P3.1.2.16 and give a Start command within 20 seconds. If the Start command is not
given on time, the P3.1.2.16 identification will not be performed, the values will not be tuned, settings will remain
unchanged, and an alarm will be triggered.
To interrupt the identification process, press the stop button. The process will be aborted, settings changes will not
be considered, and an alarm will be triggered
NOTE: When the identification process has ended, a Start command is needed to run the motor.
P3.1.2.17 MID FREQUENCY U/f (ID 604)
You can use this parameter to set the U/f for the power supplied to the motor.
NOTE:
In order to be able to set the mid frequency, the U/f ratio P3.1.2.7 must be programmable.
P3.1.2.17 MID VOLTAGE U/f (ID 605)
You can use this parameter to set the midpoint voltage of the U/f curve.
NOTE:
In order to be able to set the mid frequency; the U/f ratio P3.1.2.7 must be programmable.
P3.1.2.19 MOTOR PREHEAT (ID 1045)
You can use this parameter to control the motor temperature before the start.
Description
Identification will not be performed.
The identification process performs without running the motor. The motor is supplied
with voltage and current but always at frequency zero.
The identification process performs and the motor will run. The U/f ratio and
magnetization are identified.
To obtain precise results, use this function with no load connected to the motor.
