4.2.4
Identifying the motor data and optimizing the closed-loop control
The inverter has several techniques to automatically identify the motor data and optimize the
speed control.
To start the motor data identification routine, you must switch-on the motor via the terminal
strip, fieldbus or from the operator panel.
WARNING
Risk of death due to machine motion while motor data identification is active
For the stationary measurement, the motor can make several rotations. The rotating
measurement accelerates the motor up to its rated speed. Secure dangerous machine
parts before starting motor data identification:
• Before switching on, ensure that nobody is working on the machine or located within its
working area.
• Secure the machine's work area against unintended access.
• Lower hanging/suspended loads to the floor.

Preconditions
● You selected a method of motor data identification during quick commissioning, e.g.
measuring motor data while the motor is stationary.
When quick commissioning is complete, the inverter issues alarm A07991.
● The motor has cooled down to the ambient temperature.
An excessively high motor temperature falsifies the motor data identification results.
Procedure when using the BOP-2 operator panel
To start the motor data identification, proceed as follows:
Press the HAND/AUTO key.
The BOP-2 displays the symbol indicating manual operation.
Switch on the motor.
During motor data identification, "MOT-ID" flashes on the BOP-2.
If the inverter again outputs alarm A07991, then it waits for a new ON command to start the
rotating measurement.
If the inverter does not output alarm A07991, switch off the motor as described below, and
switch over the inverter control from HAND to AUTO.
Switch on the motor to start the rotating measurement.
During motor data identification, "MOT-ID" flashes on the BOP-2.
The motor data identification can take up to 2 minutes depending on the rated motor power.
Depending on the setting, after motor data identification has been completed, the inverter
switches off the motor - or it accelerates it to the setpoint.
If required, switch off the motor.
Switch the inverter control from HAND to AUTO.
You have completed the motor data identification.

Connecting the inverter to the fieldbus
Where can I find instructions for the fieldbus connection of the inverter?
Instructions for connecting to a fieldbus can be downloaded from the Internet:
● Application examples (http://support.automation.siemens.com/WW/view/en/60733299)
● Operating Instructions: CU240B/E-2 operating instructions

● "Fieldbuses" function manual: Manuals for the Control Unit
(http://support.automation.siemens.com/WW/view/en/30563628/133300)
Description files for fieldbuses
The description files are electronic device data sheets which contain all the required
information of a higher-level controller. You can configure and operate the inverter on a
fieldbus with the appropriate description file.
Generic Station Description for PROFIBUS: GSD
(http://support.automation.siemens.com/WW/view/en/23450835)
GSD Markup Language for PROFINET: GSDML
(http://support.automation.siemens.com/WW/view/en/26641490)
Ethernet/IP: EDS (http://support.automation.siemens.com/WW/view/en/78026217)
Alternative for the download for GSD and GSDML
GSD and GSDML are saved in the inverter. If you set p0804 = 12, then the inverter writes
the GSD or the GSDML to the memory card that has been inserted. For instance, you can
transfer the file to a PC from the memory card.
