Calculating The Motor And Control Data - Siemens SINAMICS CU240S DP-F Operating Instructions Manual

Next to "Quick Commissioning"
Next to "Quick Commissioning" the motor data should be calculated. This can be done
automatically via "Motor Data Identification" or manually via setting the parameters P0340 ...
P0360.
Additionally in case of vector mode (P1300 = 20/21) the "Speed Control Optimization" should
be performed.
Note
"Motor Data Identification" and "Speed Control Optimization" need an ON command to start.

Calculating the Motor and Control Data

Automatic Calculation via Motor Data Identification
The motor data identification routine MUST not be used for loads which are potentially
hazardous (for example, suspended loads for crane applications). Before the motor data
identification routine is started, the potentially hazardous load must be carefully secured (for
example, by lowering the load to the floor or by clamping the load using the motor holding
brake).
Parameter Description
P0625 = ... Ambient motor temperature (entered in °C)
The motor ambient temperature is entered at the instant that motor data is being determined (factory
setting: 20 °C).
The difference between the motor temperature and the motor ambient temperature P0625 must lie in the
tolerance range of approx. ± 5 °C.
If not the motor must be allowed to cool down.
P0010 = 0 Commissioning parameter filter*
Check if P0010 = 0 (Ready)
P1900 = 3 Select motor data identification*
0: Disabled (default)
2: Identification of all parameters in standstill.
3: Identification of all parameters in standstill including saturation curve
ON command Start motor data identification
Once P1900 ≠ 0, alarm A0541 is generated that states, the next ON command will initiate the motor data
identification. When the ON Command is given, current flows through the motor and the rotor aligns itself.
Note: When motor data identification is complete A0541 will be cleared and P1900 will be set to zero.
OFF1 In order to set the inverter into a defined state, an OFF1 command must be issued before the next step.
With the OFF1 command the motor data identification is finished.
