Description: Sets the configuration for the motor data identification.
Bit field: Bit Signal name
00 Stator inductance estimate no measure-
ment
02 Rotor time constant estimate no measure-
ment
03 Leakage inductance estimate no measure-
ment
05 Determine Tr and Lsig evaluation in the time
range
06 Activate vibration damping
07 De-activate vibration detection
11 De-activate pulse measurement Lq Ld
12 De-activate rotor resistance Rr measure-
ment
14 De-activate valve interlocking time mea-
surement
15 Determine only stator resistance, valve volt-
age fault, dead time
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.
