SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 01/2011

Description: Sets the configuration for the motor data identification.

Note: The following applies to permanent-magnet synchronous motors:

Without de-selection in bit 11, in the closed-loop control mode, the direct inductance LD and the quadrature induc-

tance Lq are measured at a low current.

When de-selecting with bit 11 or in the U/f mode, the stator inductance is measured at half the rated motor current.

If the stator is inductance is not measured but is to be estimated, then bit 0 should be set and bit 11 should be de-

selected.
