5 Operation
5.1 Permanent magnet synchronous machine (PMSM)
– Configuration 806
5.1.1 Operation without encoder
5.1.1.1 Start
In order to prevent the machine from tilting, PMSM will always be started with current impression.
5.1.1.2 Isd current
For operation in the basic speed range, impression of a small positive Isd current (10% of rated cur-
rent) in the machine is recommended. Thus, current will be flowing, even in open-circuit state.
The SETUP will set Parameters Ref. Isd Upper Limit 743 and Ref. Isd Lower Limit 744
automatically to 10% of the rated current (Parameter
371).
In the case of PMSM, the value entered in Parameter Isd Reference Value 743.
