5.8.3 Motor parameters (object descriptions)
0x2C01 | 0x3401 - Motor: Common parameters
Note!
In the objects 0x2C01 and 0x2C02, parameters of a motor in star connection are
described. If you want to use a motor in delta connection, the data of a winding (e.g.
from the associated data sheet of the motor) has to be converted into the equivalent
values of the star connection.
The stator resistance (object 0x2C01:2
or 0x34E0:2 for axis B) for the motor in delta
connection, for instance, is calculated as follows:
