Setting Motor Constants for Vector Control
Operations
and Monitoring
4–66
The inverter has three separate motor constant sets named 1st, 2nd, and 3rd. The 1st motor
constant set is the default, while the SET and SET2 intelligent inputs select the 2nd and 3rd
constant sets, respectively. The torque control methods are valid to use only if a particular
motor constant set includes parameters for the selected control method. The following table
lists the vector control methods and shows the ones that are valid for each motor constant set.:
The motor data selection is available only to the 1st motor constant set, selected by function
H004. By default, the 2nd and 3rd motor constants sets only store standard motor parameters.
The table below shows this arrangement.
When motor constant values are available from the motor manufacturer, you can enter them
directly. The available motor constant parameters (storage locations) depend on the motor
constant set (1st, 2nd, or 3rd) according to the following table.
