Parameter
P3.1.4.2 (Field Weakening Point Frequency)
P3.1.4.3 (Voltage at Field Weakening Point)
11.3.2.2 (ID 601) Switching Frequency
Location in the menu: P3.1.2.3
Use this parameter to set the switching frequency of the AC drive.
If the switching frequency is increased, the capacity of the AC drive reduces. To reduce capacitive currents in the motor cable, when
the cable is long, we recommend using a low switching frequency. To reduce the motor noise, use a high switching frequency.
11.3.2.3 (ID 631) Identification
Location in the menu: P3.1.2.4
Use this parameter to find the parameter values that are optimal for the operation of the drive.
The identification run calculates or measures the motor parameters that are necessary for a good control of the motor and speed.
The identification run helps to adjust the motor-specific and the drive-specific parameters. It is a tool for the commissioning and the
servicing of the drive.
Before the identification run, set the motor nameplate parameters.

To activate the Identification function, set the parameter P3.1.2.4 and give a start command. The start command must be given in
20 s. If there is no start command in that time, the identification run does not start. The parameter P3.1.2.4 is reset to the default
value and an identification alarm shows.
To stop the identification run before it is completed, give a stop command. This resets the parameter to the default value. If the
identification run is not completed, an identification alarm shows.
To start the drive after the identification, a new start command is necessary.
11.3.2.4 (ID 612) Magnetizing Current
Location in the menu: P3.1.2.5
Use this parameter to set the magnetizing current of the motor.
The magnetizing current (no-load current) of the motor identifies the values of the U/f parameters when they are given before the
identification run. If the value is set to 0, the magnetizing current is calculated internally.
11.3.2.5 (ID 653) Motor Switch
Location in the menu: P3.1.2.6
Use this parameter to enable the Motor Switch function. Use the Motor Switch function, if the cable that connects the motor and
the drive has a motor switch. The operation of the motor switch makes sure that the motor is isolated from the voltage source and
does not start during the servicing.

Description
No identification requested.
The drive operates without speed when doing the identification run for the motor parame-
ters. The motor receives current and voltage, but the frequency is zero. The U/f ratio and start
magnetization parameters are identified.
The drive operates with speed when doing the identification run for the motor parameters.
The U/f ratio, the magnetization current and start magnetization parameters are identified.
To get accurate results, do this identification run with no load on the motor shaft.
