When this parameter is changed, parameters P3.1.4.2 and P3.1.4.3 will be automatically ini-
tialized according to the selected motor type.
See Table 110 for the initialization values:

The automatic motor identification calculates or measures the motor parameters that are
needed for optimum motor and speed control.
Identification Run is a part of tuning the motor and the drive specific parameters. It is a tool for
commissioning and service of the drive with the aim to find as good parameter values as pos-
sible for most drives.
NOTE: Motor nameplate parameters have to be set before executing the identification run.

The automatic identification is activated by setting this parameter to desired value and giving
a start command in the requested direction. The start command to the drive has to be given
within 20 s. If no start command is given within this time the identification run is cancelled, the
parameter will be reset to its default setting and an
The identification run can be stopped at any time with normal stop command and the parame-
ter is reset to its default setting. An
run has failed.

No action No identification requested.
Identification at The drive is run without speed to identify the motor parameters.
standstill The motor is supplied with current and voltage but with zero fre-
quency. U/f ratio is identified.
Identification with The drive is run with speed to identify the motor parameters. U/f
motor rotating ratio and magnetization current are identified.
NOTE:
